PHANEROGAMS — PROFESSOR BAYLEY BALFOUR. 227 



specimens are entire, uniformly hairy, with gland-tipped hairs, whilst Kurz's 

 type plant has toothed bracts, often quite glabrous and not viscid. 



The Socotran species, it would appear, has 'also a tendency to variation. 

 We have another set of specimens from the island, representative ot a more 

 common plant than the one I have just referred to, which are merely miniatures 

 of it. Reduce all the parts of the species as I have described it except the 

 spikes by about one-half, and you have this second form. This may be regarded 

 as a distinct variety, of which the following is a diagnosis : —

The features, in addition to the smaller size, in which this variety differs from 

 the type are, the very long and narrow spike with internodes considerably 

 elongated, and the flowers and bracts not at all or less closely imbricated, whilst 

 the bracteoles are shorter than the calyx. 



13. DICLIPTERA. 



Dicliptera, Juss. in Ann. Mus. Par. ix. (1801), 267; Benth. et Hook. Gen. PI. ii. 1120. 



A considerable genus dispersed widely in the tropical and subtropical 

 regions of the whole world. Both the Socotran species are endemic.
