An erect very slender herb, 20-35 cm. high ; radical leaves 2-5, 

 withered during the flowering period, erect rigid narrow-linear, 

 7-20 cm. long ; scape flexuous rigid, clothed with 8-6 membranous, 

 closely appressed, setaceo-acuminate sheaths ; spike very slender, 

 densely or laxly many-flowered, the flowers ascending ; bracts 

 membranous lanceolate-ovate setaceo-acuminate, longer or 

 shorter than the flowers ; lateral sepals spreading oblong obtuse, 

 mucronulate below the apex, the mucro more or less elongated, 

 0'4-0'7 cm. long ; odd sepal ascending or erect, galeate-concave 

 obtuse, more or less elongate-mucronulate below the apex, as long as 

 the lateral sepals, the spur short, spreading or ascending, conical 

 obtuse ; petals erect, incurved at the apex, oblong obtuse, serrulate 

 on the anterior margin, 0*2-0'3 cm. long ; lip porrect or deflexed, 

 linear or oblong, very obtuse or acute, the margin entire or serru- 

 late, 0"2-0"3 cm. long ; rostellum short, entire at the apex ; anther 

 horizontal, the gland solitary, almost quadrate ; stigma depressed 

 marginate ; ovary 0'4-0*6 cm. long. 



Described from several dried and living specimens. The 

 drawings of tab. 71 were made from specimens collected on the 

 Cape Peninsula ; that figured under A having been brought by 

 Mr. Bodkin (Bolus, 4874), and that under B by Mr. R. du Toit 

 (Bolus, 13509) : those figured under tab. 72 were both specimens 

 collected by the former at Houw Hoek. 



The colour of the flowers (of the form collected on the Penin- 

 sula) is greenish with occasional purple spots, while that of those 

 from Houw Hoek is pale purple or rosy. At the latter place was 

 found another form, with a very long and distantly flowered 

 spike and greenish flowers. The tuber is irregular in shape and 

 sometimes large, resembling those of the section Herschelia.
