exceeding the ovaries, flowers somewhat nodding ; side sepals 

 superior posticous approximate reflexed lanceolate concave, in- 

 flated at base, together with the odd sepal and petals about 

 8 mill, long ; odd sepal and petals reversed and hanging down 

 in front of the flower, the sepal lanceolate vaulted, the petals 

 oblong concave much larger than the sepals ; limb of the lip 

 superior ascending, transversely oblong, concave, crenulate 

 clawed, about 3 mill, long ; the appendix larger deflexed tongue- 

 shaped bilobed fleshy, about 5-6 mill, long ; cells of the anther 

 remote, situate at the ends of the arms of the rostellum ; ovary 

 cylindrical, twisted above. 



Described from several living specimens from Piquetberg, and 

 one from Hex E. Valley. Colour of the flowers greenish yellow, 

 with brown-purple stripes on the lij), and sometimes also on the 

 petals ; sepals and bracts green, or sometimes brown on the 

 upper portion. A very distinct species readily known from any 

 other except Pt. Flanagani, mihi, by the reversed position of its 

 flowers, "which is effected (as in Disa elegans, see Plate 35) by an 

 entire instead of a half twist in its ovary. It was first discovered 

 by Thunberg in 1774 near Piquetberg, where I also found it 

 tolerably abundant during a very pleasant botanical excursion, 

 with my friends Professors Guthrie and Bodkin, exactly 118 

 years later. Thunberg, like Drege at a later date, travelled 

 slowly northward by that route, and both gathered at the same 

 spot several very local plants which it was a great satisfaction to 

 us to obtain again in the same neighbourhood. Botanists will 

 always find the village of Piquetberg an excellent centre for 

 excursions.
