Hah. Usagara Mountains, Bishop Hannington. 



Statura adspectuque omnino G. Afzelii ; folia longitudine 

 latitudinem quinquies siiperant. 



In its leaves having no limb this species is distinct from the 

 other African species, and comes nearer to the wide-spread 

 C Dozyanum of the Indian Archipelago and Pacific Islands. 



Ststegium, Bruch et ScTiimp. 



S. UNauicuLATUM, sp. n. Caulis brevis simplex ramosusve ; 

 folia in comam disposita patentia sicca incurvata crispata elongate 

 lanceolata, perichsetialia paululum latiora omnia canaliculata 

 marginibus superioribus involutis, nervo latiusculo in mucronem 

 nnguicularem excurrente, cellulis minutis rotuudis inferioribus 

 oblongis; theca parva immersa ovali-globosa, calyptra stylo 

 elongato. 



Sah. Qua Chiropa. 



Caules in csespitibus laxis aggregati 1*50 mm. alti. Folia Ion- 

 giora 2 mm. longa luteo-viridia, nervo pallidiore ; theca pallide 

 aurantiaca, 0'25 mm. longa. 



Smaller than the European S. crispum, but corresponding 

 generally with it ; and nearly similar species seem to be found in 

 India and S. America. 



Htophila, G. MiilL 



H. PLTCATA, sp. n. (PL XV. figs. 13-16.) Monoiea, gregarie 

 cfiEJspitosa humilis ; caulis inferne foliis parvis sparsis apice rosu- 

 latim f oliatus ; folia patula obovata spathulata obtusissima inte- 

 gerrima, nervo ad apicem percurrente Isevi, cellulis superioribus 

 parvis rotundatis basalibus majoribus quadratis pallidioribus, 

 perichsetialia ovali-oblonga obtusa ; theca in pedunculo gracili 

 pa] lido erecta elongate ovali-cyhndracea acute octangulata, oper- 

 culo conico acuminato recto, peristomio brevi dentibus subulatis 

 solidis rubris Isevibus infra os insertis 16 annulo composite; 

 flos masculus foemineo similis.

In its manner of growth and foliage this resembles many 

 species of Mosses referred to Hyophila^ such as H.javanica and 

 H. involuta ; but the plicate capsule is peculiar, and the peristome 

 is rather that of a Weisia than of an incomplete Tortula,
