never verticillate, the long pedicels, the strongly-reflexed, distinctly 

 ciliate corolla-lobes, the different corona-scales, the large mem- 

 branous appendage of the anthers, and the somewhat different 

 pollinia. According to the collector, the flowers are lilac. This 

 species is only known to me from the above-mentioned locality. 



Harvey's figure of S. fasciculare (T/ies. Cap. i. t. 90) gives a 

 pretty good idea of the general appearance of that species, although 

 the details given besides are, as in many cases in this work, in- 

 correct.

Although agreeing in habit with other species of Schizoglossum, 

 I am still in doubt whether this plant really belongs to the genus, 

 as there are several differences which may justify its generic 

 separation. I possess two more species which are doubtless con- 

 generic with our plant, one from East Griqualand, collected by 

 Tyson, the other from the lofty summit of Mont aux Sources, 

 collected by Mr. J. Thode. In all three I note a most singular 

 structure of the pollinia ; their form is almost oblique-pyriform, but 

 the inner margin is suddenly thinned, so much so that the pollinia 

 appear there almost transparent. The two lamelhe on the inner 

 side of the corona-scales are hardly visible, and of a very thin 

 texture.
