Acampe pachyglossa

 

  • Acampe pachyglossa by Lourens Grobler

Description

Acampe pachyglossa is a robust epiphytic plant, sometimes forming small clumps of four to five plants growing together. The stems are stiff and quite woody, while the roots are 6-8 millimetres in diameter. The succulent leaves are placed in two opposite rows along the stem and measure up to 250 millimetres long by 15-25 millimetres wide. The leaves are deeply folded and appear ‘vee-shaped’ in cross-section, with unequally bilobed tips. The flowers are fleshy, with pale yellow sepals and petals that have reddish-purple bands. The lip is white or yellow-white, with a few small purplish spots.

 

Eulophia streptopetala

  • Eulophia streptopetala by Duncan McFarlane

 

Description

Robust terrestrial with flowering stems that can grow up to 2.5m tall. The pseudobulb grows partially above the ground (much like a Cymbidium) and is up to 40 mm in diameter. The new growths develop from the base of the previous seasons matured pseudobulbs and the leaves are partially to fully developed when flowering. Leaves number between 4 and 9 and have a distinct ribbing appearance. The inflorescences, which grow next to the new growth with the developing pseudobulb, carries between 10 and 40 flowers. These are borne sequentially. Sepals are olive-green to green and are suffused with a reddish-brown. The petals are a chrome-yellow colour. No fragrance has been detected. The spur is 2mm in length.

 

Margelliantha caffra

 

  • Margelliantha caffra by Lourens Grobler

Description

Miniature epiphyte with stems up to 20mm. Leaves few or occasionally absent, linear to strap-shaped and unequally bilobed. Inflorescence lateral, one to several, hanging from below the leaves, up to 45 mm long. 5-15 flowers close to each other, which are white with a green anther cap. Previously allocated top the genus Mystacidium and Diaphananthe, before being recognised under the current genus name. 

 

Neobolusia tysonii

 

  • Neobolusia tysonii by Gerrit van Ede

Description

Slender terrestrial up to 400mm in height. Stem has a raised ridge along it's length. Leaves 2 basal, spreading, narrowly elliptic to oblong up to 155mm long, a few small sheathing leaves higher up. Inflorescence lax, up to 150mm long, with 2-12 flowers which have brownish green sepals, off white petals, white lip with pink markings at the base. Spur is absent.

 

Platylepis glandulosa

 

Description

Creeping terrestrial becoming erect, up to 500mm tall. Leaves evident only on the bottom half of the erect section, stalked with conspicuous veins, egg shaped, up to 50mm long. Inflorescence congested, ovoid, conspicuously hairy, up to 100mm tall. Flowers green to greenish brown and white, lip white. Median sepal forms a hood with the petals. This genus has only one species.   

Stenoglottis fimbriata

 

  • Stenoglottis fimbriata by Lourens Grobler

Description

Slender epiphyte, lithophyte, or terrestrial, which can grow up to 400mm tall. Leaves 6-10 in a basal rosette, strap-shaped to narrowly spear-shaped, spotted, with wavy fringes. Inflorescences lax, 5-30 flowers, which are lilac with darker spots. Sepals  similar and up to 8mm long, petals are shorter and enclose the column. Spur absent. A very variable species in size and colouration. The fleshy, hairy roots attach themselves onto quite steep rock faces, preventing excess water and debris accumulating. Colony forming. 

 

Stenoglottis longifolia

 

Description 

Fairly robust lithophyte or epiphyte, up to 600mm tall. Leaves 6-10 in a basal rosette, strap-shaped to narrowly elliptic, uniformly green, margins slightly wavy. Inflorescence lax to dense, up to 80 flowers that are lilac to white with darker spots all over. Sepals similar, up to 10mm long. Petals shorter than sepals, enclosing the column. Lip 5-lobed. Spur absent. 

 

Stenoglottis woodii

 

  • Disperis woodii by Martin Rautenbach

Description

Slender terrestrial or lithophyte, up to 200mm tall. Leaves 5-20 in a basal rosette, narrowly elliptic to egg-shaped, uniformly coloured. Inflorescence lax, 4-20 flowers, white to pink, often with purple spots at the base. Sepals similar, up to 5mm long. Petals erect, 3,5mm long.

 

Stenoglottis zambesiaca

 

  • Stenoglottis zambesiaca by Lourens Grobler

Description

Very slender lithophyte, or rarely an epiphyte, up to 350mm tall. Leaves 6-12 in a basal rosette, strap to narrowly spear-shaped, uniformly covered or sometimes spotted, or slightly wavy. Inflorescsence lax, flowers lax, pale lilac or pink, lip darker and spotted. Column enclosed by petals. Spur absent. 

 

Tridactyle bicaudata subsp. bicaudata.

 

Description

Slender to robust epiphyte or lithophyte, stems stout, usually erect, up to 350mm long and 4-6mm in diameter, roots separated from leaves by a length of bare stem. Leaves in 2 opposite rows, leathery, linear to strap-shaped, rounded, unequally bilobed. Inflorescences  dense, appearing from the axils of the leaves, 30-80mm long, 6-20 flowers, upward facing, palish yellow to brown. Also see subs. rupestris.
