334 BOTANY OF SOCOTRA. 



half an inch. In colour, all the specimens are of a dark brown. Besides the 

 form gathered in Socotra, there is another in Kew Herbarium from the " Shores 

 of the Red Sea," * which was named S. rugifolia by Mr Wilson, at a time when 

 the species of the genus were supposed to be much fewer in number than is now 

 known to be the case. 



S. Balfonrii belongs to the same group of species as the African S. mntrosa, 

 C. Mull. (Synops. Muse. i. 756), and S. ferruginea, Brid. (Br. Univ. i. 743) ; 

 but it more nearly resembles the Indian S. Grevilleana, Mitt. (Linn. Soc. Jour, 

 i.) All these have the perichaetial leaves not obviously different in form or 

 length from those of the branches. 



7. PHILONOTIS. 

 PMlonotis, Brid. Br. Muse. ii. 15, t. 6. 



A genus frequently considered a section of Bartramia, widely spread in 

 tropical and temperate regions. 



P. pungens, Mitt. 



Bartramia (PMlonotis) pungens, Mitt, in Trans. Eoy. Soc. 168 (extra vol.), 390, t. 37, A. 



Socotra. On the slope of Haghier behind Tamaricla. B.C.S. nn. 1419 

 pro parte, 1427. 



Disteib. Rodriguez. 



Small barren stems which seem to be identical with this species. 



8. BRACHYMENIUM. 



Bracliymcnium, Hook, in Swsegr. Sp. Muse. Suppl. ii. 1, 131, 135. 



A considerable genus of tropical regions, now commonly included in Bryum. 



Brachymenium sp. 



A few barren stems growing on a small branch with Lejeunia and Frullania 

 (n. 1440), are just sufficient to indicate the presence of a species near to the 

 Indian B. nipalense, Hook, (in Swsegr. Sp. Muse. Suppl. ii. 1, 131, t. 135). 



9. BRYUM. 



B^im, Linn. Gen. n. 1194. 



A vast cosmopolitan genus. 



? B. dichotomum, Hedw. Sp. Muse. 183, t. 48, ff. 8-12; C. Mull. 

 Synops. Muse. i. 304. 



A few barren stems of a species near to this grow with PMlonotis pungens, 

 Mitt. 



* [It is possible this plant so marked may have been sent by Nimmo, and is therefore Socotran, but 

 there is no means of determining this. — B.B.]
