332 BOTANY OF SOCOTRA. 



A small moss, which at first sight might easily be passed over as a Weisia 

 allied to W. controversa (Hedw. Sp. Muse. 67, and Muse. Frond, iii. 12, t. 5, B) ; 

 in some of the specimens the stem is very short, in others which are taller it does 

 not exceed half an inch in height ; the resemblance and form of the leaves with 

 their thickened nerve is much more with W. rupestris, Hedw. (Sp. Muse. 72, t. 

 14, ff. Q-12 = Gymnostomum rupestre, Swsegr. Sp. Muse. Suppl. i. 1, 31, t. 11). 

 It is a little more robust than the species collected in Abyssinia by Schimper, 

 and distributed as Gymnostomum ocanthocarpum, var. gracilescens caps, minore, 

 Hook, (in herb. Schimp. Abyss, sect. ii. n. 480). 



2. W. (Hyophila) punctulata, Mitt. 



Humilis; folia patula spathulata acuta planiuscula nervo in mucronulo brevissimo excurrente 

 margine apicem versus minute serrulata cellulis minutissimis indistinctis quasi rninutissime 

 puuetatis baud opacis basalibus paucis quadratis pellucidis areolatis. 



Caulis 02-03- Folia viridia sicca involuta. 



Soeotra. On Haghier. B.C.S. 1451. 



Distrib. Endemic. 



Very nearly allied to the Indian W. (Hyophila) involuta, Hook. (Muse. Exot, 

 t. 154, Gymnostomum), but with leaves less rigid and more minutely serrulate. 

 W. (Hyophila) Potieri, Besch. from Nossi Comba, Nossi Be, and Reunion, 

 appears from the description to be a similar species, but the leaves are said to 

 be opaque and the basal cells hexagonal. 



4. TORTULA. 



Tortula, Hedw. Fundam. Muse. ii. 92. 



A vast genus of all regions of the globe. 



T. csespitosa, Schwaegr. Sp. Muse. Suppl. i. 1. 120, t. 31. 



Tortula Northiana, Grev. in Trans. Linn. Soc. xv. (1827), 42, t. 3, f. 4. 

 Barbula Northiana, C. Mull. Syuops. Muse. i. 602. 



Soeotra. On Haghier, at considerable elevation. B.C.S. 1454. 



Distrib. Mediterranean Europe, West Indies, and South America; 

 it appears also in south Africa, but has not yet been identified amongst Indian 

 mosses. 



A few barren stems appear to be this species. 



5. ANICTANGIUM. 



Anictangium, Hedw. Sp. Muse. 1, 40. 



The species of this genus all intimately resemble each other ; they are found 

 in all temperate regions, and are especially inhabitants of mountain rocks. 



A. Mariei, Besch. in Rev. Bryol. 1880, 18.
