bracts ; side sepals oblong obtuse apiculate, somewhat twisted, 

 1-2 cm. long ; odd sepal posticous galeate oblong obtuse, spur 

 from a funnel-shaped base filiform, a little shorter than the 

 limb ; petals half exserted beyond the galea erect falcate-oblong 

 obtuse apiculate, 6-10 mill, long ; lip spreading linear widened 

 and thickened towards the apex, a little longer than the sepals ; 

 rostellum short; ovary slender straight, l"5-2"8 cm. long. 



Described from numerous living and dried specimens ; the 

 drawing from a living plant sent by Dr. Schoenland, gathered 

 near Grahamstown early in December, 1889. Colour of the 

 flowers clear rose-pink, with or without darker spots, or lilac 

 with purple spots. This is a very variable species, especially as 

 to the size of the raceme, the size and colour of the flowers, and 

 the texture of the leaves. In some specimens the latter are 

 strongly nerved, but this may be, as is often the case, the result 

 of drying. Of the numerous living specimens I have seen all 

 were nerveless. It is impossible to find any valid distinctions 

 between Sonder's I), patula and the present species ; and I have 

 satisfied myself, after again finding a similar plant to that on 

 which my D. stenoglossa was founded, that it is only a de- 

 pauperated state of this species, with which I was, at the time 

 I described the former, but little acquainted. D. nervosa is most 

 nearly allied to IK pulchra, Sonder.
