BRYOPHYTA OF S. RHODESIA. 333 



sule very small, erect, elliptic, rather wide-mouthed when dry, 

 thin-walled, having the exothecium cells wide and isodiametric, 

 with very thin walls. Peristome teeth very highly lamellate, or 

 cristate, within. 



POTTIACEAE. 



Hymenostomum eurybasis sp. now Dixon. 



A speciebus africanis affinibus (H . socotranum, Weisia 

 viridula, etc.) differt foliis siccis /are incurvo-flexuosis, nee 

 fortiter incurvis, costa tenuiore, siccitate dorso Itaud nitida, apice 

 plerumque obtuso vel brevissime apiculato, marginibus late involu- 

 tes basi folii plus minusve distinct e, aliquando abrwpte dilatata, 

 hyalina. Seta circa 4 mm. alta, tenuis, flava, theca aurantiaca, 

 sicca sub ore leniter constricta; peristomium nullum, orificium 

 principio hymenio clausum. 



Habitat: On earth, Matopos, Mchelele Valley, alt. 4,700 feet 

 (Eyles, 940, 941); (v. supra). Hellet's Concession, Magude, alt. 

 500 feet (Sim, 8989). 



Stems rather taller than in most of the allied species, from 

 which it is not widely distinct, but the characters italicized above 

 make it difficult to unite it with any of those described. The apex 

 of the leaf is generally quite obtuse and subcucullate, with the 

 margins strongly incurved ; and the leaves not shining at back 

 and not strongly crisped when dry seem marked features, though 

 these characters are to some extent shared by //. socotranum 

 Mitt. 



Hyophila atrovirens (CM.) Jaeg. — On lime, Hellet's Con- 

 cession, Magude (Sim, 8991, 8992, 8994). 



Hyophila Zeyheri (Hampe) Jaeg. — Hellet's Concession, 

 Magude, on lime, alt, 500 feet (Sim, 8993). 



FUNARIACEAE. 



Micropoma niloticum (Del.) Lindb. — On soil, Antioka (Junod, 

 323). 



A most interesting discovery; the plant has, so far as I know, 

 not been recorded elsewhere than from its original gathering in 

 Lower Egypt early in the nineteenth century. The present plant 

 agrees exactly with the Egyptian specimens at Kew, except in 

 being a slightly smaller form. 



A second species, M. hukobense, has been described by 

 Brotherus from Central Africa, differing from J/, viloticum — - 

 apparently very slightly — in the form of the leaves. 



PJn/scomitrium spathulatum CM. — Shirindjen, at low alti- 

 tudes (junod, 332). 



General distribution : Cape Province, Natal, Transvaal, 

 Southern Rhodesia. 



I was at first inclined to separate this plant as P. poculiforme 

 Mitt. MS. in herb. Mitten's specimen from Port Natal agrees
