A glabrous erect herb, |-1 foot or more in height ; stera 

 straight or occasionally flexuous, loosely and distantly leafy; 

 radical leaf spreading ovate or oblong acute, 6-10 cm. long, the 

 upper more erect smaller, passing gradually into bract-like 

 sheaths; spike cylindrical many-fl., bracts lanceolate deflexed, 

 flowers about 1'2 cm. long, 8 mill, wide ; side sepals spreading 

 ovate acute or subobtuse ; odd sepal oblong very obtuse ; petals 

 subtriangular, the upper margins folded over downward; limb 

 of the lip broadly triangular-hastate acute, with a spreading 

 tooth-like fold on either side near the base, appendage about 

 equally long erect cup-shaped, with an oblique marghi entire or 

 emarginate or dentate in front; connective of the anther as- 

 cending incurved somewhat half-ring-shaped, the cells inverted, 

 glands inferior; arms of the rostellum adnate to the connective 

 of the anther ; stigmas 2, placed one on either side of the 

 appendage of the lip, at its base. 



Described and drawn from a living plant gathered near Cape 

 Town ; and I have seen many others from other stations. 

 Colour of the flowers sulphur yellow, the whole plant drying 

 pale. Lindley separated this plant from Pterygodium because, 

 as he said, of " its anther being perfectly erect." Bentham, 

 however, in Genera Plantanun, replaced it in Pterygodium, 

 calling the anther suberect, and I agree in this view. The 

 position of the anther is not widely different from that of 

 Pt. carnosum, Lindley, as shown in my Orchids of the Cape 

 Peninsula, t. 12, f. 7. In this species the connective of the 

 anther is differentiated from the rostellum, although they are 

 partially adnate. In other species these bodies seem to coalesce 

 into one.
