Eriospermum cervicorne

82. Eriospermum cervicorne Marloth, S. Afr. Gard 19: 327(1929); Duthie, Ann. Univ. Stellenb. 18(A2): 52(1940). Type: South Africa, Cape Province, Springbok, Meyer sub Marloth 6983 (PRE: holotype).

Plants with hysteranthous leaves, solitary, inflorescence up to 120 mm high.

Tuber simple, pyriform to oblong or irregular in shape, up to 70 mm long and 40 mm wide; skin brown, interior pink becoming maroon red in the older part; growing point lateral to basal.

Old leaf sheaths up to 100 mm long and 5 mm diameter widening to 18 mm at ground level, light brown, membranous.

Leaf solitary, sub-erect or spreading horizontally; contemporary leaf sheath exserted up to 40 mm, up to 4 mm diameter, maroon red, glabrous or covered with curly, white hairs; lamina narrowly to broadly ovate-cordate, acute, up to 20 mm long and 15 mm wide, apex often recurved, abaxial surface reddish-green, sparsely hairy, adaxial surface dark green, producing few to numerous branched enations, more or less terete, up to 45 mm long and 3 mm wide, dark green, fleshy, sparsely to densely covered with curly white hairs.

Peduncular bract barely exserted or up to 5 mm, upper 3 mm non-sheathing, ovate, apex acute, retrorse, green with red streaking, glabrous; margin red.

Peduncle 35-60 mm long, 1.0-1.5 mm diameter, glaucous with red striations, glabrous.

Raceme cylindrical with a pointed apex, up to 70 mm long, 25 mm wide at the base, with up to 21 flowers.

Bracts triangular, sometimes somewhat cymbiform or spurred, 1.0-1.5 mm long with acuminate apex, membranous, transparent with a reddish-brown midnerve.

Pedicels erecto-patent, arcuate, lower up to 10 mm long, upper slightly shorter.

Flowers triangular, spreading, up to 14 mm diameter.

Tepals dimorphic, connate for 1.5 mm at the base, white with a dark green midnerve overlaid with faint red striations; outer tepals spreading with a recurved sometimes slightly twisted apex, narrowly elliptic to linear, attenuate, 7-8 mm long and 2 mm wide, inner suberect, spathulate with a crisped, connivent apex, 6-7 mm long and 2 mm wide.

Filaments forming a ring round the ovary with anthers touching, subequal, outer adnate about 1 mm up the tepals, triangular, 2 mm long and 1.0-1.3 mm wide at the base, white with purple blotches; inner adnate nearly 2 mm up the tepals, 1.8 mm long and 1 mm wide at the base, white.

Ovary subglobose, 1.8 mm long and wide, dark green, spotted red between the locules.

Style cylindrical, 1.8 mm long, white.

Flowering time: March to April.

Leafing period: April to October.

Distribution and habitat: E.cervicorne is comparatively rare, centred in northern Namaqualand, where it has been found in loamy soil amongst granite rocks. It has outlying localities in the south near Bitterfontein and in the Tanqua Karoo (Figure 146).














Diagnostic features: E.cervicorne appears to be closest to E.multifidum and may be separated from that species by the less numerous, slightly broader and shorter enations which are sparsely to densely covered with curly white hairs, as opposed to the narrower, bright green, glabrous enations of E.multifidum. The inflorescence in E.cervicorne is less dense and the pedicels somewhat longer. The type specimen quoted by Marloth, no. 6983, was collected by Rev.G.Meyer near Steinkopf according to Marloth's description. However, the label on the Pretoria specimen records that it was from Springbok. A second specimen on the same sheet, no. 13416 is from Steinkopf. Although Marloth described the leaf and enations as glabrous, the usual long white hairs are clearly visible on the type specimen. The material at Stellenbosch was apparently produced from tubers cultivated over a number of years.

Peduncular bract barely exserted, ovate attenuate, apex retrorse, white, membranous, pinkish-red.

Peduncle up to 220 mm long and 1 mm diameter, green with red streaking especially at the base.

Raceme lax, up to 90 mm long, 35 mm wide, with up to 26 flowers.

Bracts triangular attenuate, 1.0-1.5 mm long, membranous, white with a thin brown midnerve.

Pedicels 25 mm long, pale green, arcuate, with flowers facing upwards.

Flowers campanulate, becoming spreading with a triangular outline when fully open, 12 mm diameter.

Tepals dimorphic, white with a dark green midnerve, overlaid with red streaking; outer tepals spreading, elliptic attenuate, apex recurved, 5 mm long and 2 mm wide, inner erect, broadly spathulate, with a crisped connivent apex. 5 mm long and 3 mm wide.

Filaments dimorphic, white, outer 1.3 mm long and wide, inner adnate 1 mm up the tepals, 1 mm long and 0.8 mm wide.

Ovary globose, 1.5 mm long and wide, green.

Style cylindrical, 1.5-2.0 mm long, white.

Flowering time: February to March.

Leafing period: April to October.

Distribution and habitat: E.proliferum has a wide distribution in the winter rainfall area of the Cape. It appears to be concentrated in the south west corner of the Province but that may be due to higher collecting activity as much as to actual distribution. It is usually found in rocky, shady places on well-drained clayey or sandy soils amongst Karoo or Fynbos vegetation (Figure 103).














Diagnostic features: This is a distinctive species in the leafing stage when plants are fully developed. The hairines of the leaf sheath and the long, thin hairy enations are unlike those in any other species. The rather few-flowered, dainty inflorescence helps to separate E.proliferum from similar species with dimorphic tepals (Figure 104).

Flowering time: April to May.

Leafing period: May to October.

Distribution and habitat: E.paradoxum is distributed widely in the winter rainfail area of the Cape Province, from the Richtersveld in the north-west to near Grahamstown in the south-east. It is found on sandy flats amongst Fynbos vegetation or on clayey soils amongst karroid shrubs (Figure 62).




















Diagnostic features: The compact inflorescence of comparatively large, scented white flowers is so distinctive that E.paradoxum cannot be confused with any other species of Eriospermum. The much-branched enation on the leaf is also very distinctive (Figure 63).















According to Duthie (1940) the type material was probably collected by Boos & Scholl and grown at Schonbrun. It was figured and described by Jacquin in 1796 under the name Ornithogalum paradoxum.

Ovary globose, 1.5 mm long and wide, green.

Style cylindrical, 1.3 mm long, white.

Flowering time: March to April.

Leafing period: April to October.

Distribution and habitat: E.flabellatum appears to have a limited distribution in an area from the vicinity of Laingsburg to Barrydale in the southern part of the Great Karoo. It grows in dry stony areas among succulents and karroid bushes (Figure 138).




Diagnostic features: The leaf enations and small inflorescence make E.flabellatum clearly distinguishable from all other species with the exception of E.bowieanum. However the contemporary leaf sheath in E.flabellatum is longer, more wiry and light brown in colour in comparison to the thicker, white sheath of E.bowieanum. The leaf enations are more consistent in length, more slender and a dark, shiny green in E.flabellatum, not dull, glaucous green as in E.bowieanum. The inflorescence is spicate in E.bowieanum with small globose-like flowers wheras E.flabellatum has distinct pedicels and spreading flowers (Figure 140).

Distribution and habitat: E.armianum is so far known only from one collection from the vicinity of Springbok, where an extensive population was found on talus on a cliff edge, partially shaded by shrubs (Figure 138).














Distinguishing features: In leaf this species is difficult to separate from E.bowieanum but the distributions of the two species are quite distinct. They are clearly separated in the flowering stage as E.bowieanum has a very small inflorescence with tiny almost globose flowers whereas those of E.armianum are larger (12-13 mm diameter) with spreading tepals (Figure 139).




















E.armianum is named after the collector, A.R. Mitchell, whose thorough field work in Namaqualand and Bushmanland has brought to light a number of previously unknown species.

Ovary ovoid to globose, 2mm long and wide, green with maroon streaking.

Style cylindrical, 2.5mm long, white.

Flowering time: January to April.

Leafing period: April to October.

Distriblition and habitat: E.alcicorne has a wide distribution in the arid parts of the Cape winter rainfall area, extending from northern Namaqualand to the Worcester district in the south and eastwards to the Willowmore district. It occurs on both clayey and sandy soils (Figure147).














Diagnostic features: The small, ovate, glaucous, leaf with flat, branched or unbranched enations makes E.alcicorne easy to recognize in the vegetative stage (Figure148).




















Duthie's(1940) suggestion that a specimen which Dinter found north of the Orange River with enations might be E.alcicorne remains to be confirmed. This specimen was presumably lost during World War 2 and no other records exist for Eriospermum species with enations in Namibia.

Tepals dimorphic, connate at the base only, white with a green midnerve overlaid with red stippling especially on the outer tepals; outer tepals lanceolate, 5 mm long and 1.8 mm wide, inner spathulate with slightly irregular, denticulate apical margins, 4 mm long and 2.3 mm wide.

Filaments adnate to the base of the tepals, broadly lanceolate, 1.3 mm long, outer slightly broader than the inner, white; anthers yellow.

Ovary globose, 1.3 mm long and wide, pale green sometimes with pale purplish spotting.

Style cylindrical, 1.5 mm long, white.

Flowering time: February to March.

Leafing period: April to September.

Distribution and habitat: E.bowieanum is restricted to the Worcester/Robertson area where it grows on clayey soils amongst low karroid bushes (Figure 141).














Diagnostic features: E.bowieanum may be distinguished by the small glaucous green leaf with enations which are terete and glabrous. Another species with similar enations, E.armianum, has a separate distribution in Namaqualand. Although very similar in the leafing stage the two species are quite distinct in flower, E.bowieanum having a stunted peduncle and compact inflorescence only about 55 mm long in total, with small globose flowers, whereas in E.armianum the peduncle and inflorescence are 105 mm long and the largish flowers are triangular in outline and spreading (Figure 142)
