NO. 3 BRITISH EAST AFRICAN MOSSES DIXON 7 



pai'vis, valde irregularibus, inaequalibus, parietibus flexuosis instruc- 

 tum. Peristomii clentes fusco-aurantiaci, apicibus peracutis palHdis ; 

 opaci, plus minusve pallide marginati, dense lamellati, intus alte 

 trabeculati ; endostomii membrana sat alta, aurantiaca, processubus 

 brevibus, inpcrfectis, irregularibus. Spori 25-30 fx. 



Hab. : Moorland in crater, 13,000 ft.; Nos. 3399, 3421, 3768. 



The densely imbricate leaves, erect and little altered when dry, 

 little broader above and not narrowed to base, with broad border and 

 the long, narrow, subpendulous capsule, with very distinct collum, 

 distinguish this from the allied synoicous species, most of which have 

 the leaves twisted, or at least highly flexuose, when dry. B. abys- 

 sinicmn C. M. has the leaves much narrowed to base and entire above, 

 the capsule smaller, etc. 



I have figured the peristome, showing a process in the most perfect 

 condition, but they are mostly fragmentary and more or less adherent 

 to the outer teeth. 



ANOMOBRYUM ROBUSTUM Dixon, sp. nov. 



(PI. I. fig. 4.) 



E robustioribus generis. Stirps circa 2-2.5 cm. alta, pallide viridis, 

 subnitida. Caules julacei, foliis dense confcrtis ad i.2j iiiiii. loiigis, 

 suborbicularibiis, cochleariformibus, obtusis vel obtusissime apicu- 

 latis, marginibus superioribus indistincte sinuolatis ; costa apud basin 

 60-70 jx lata, rubella, medium folium versus multo tenuior, sed parum 

 angustata, circa tertiam quartam folii attingens. Areolatio superior 

 e cellulis angustissimis, vermicularibus, parietibus firmis nee incrassa- 

 tis instructa, inferior per tertiam partem folii laxissima. 



Seta circa 1.5 cm. alta; theca e collo longo, infra in setam sensim 

 angustato atque illic curvato, oblongo-elliptica, leniter curvata, infra 

 orificium paullo contracta, badia, operculo purpiireo, obfuso, nitido. 

 Peristomium externum e dentibus aurantiacis, dense trabeculatis, 

 externe striolatis instructum, internum membrana praealta, hyalina, 

 laevi, circa f-f dentium altitudinem aequante ; processubus brevibus, 

 inferne laiis, sitperne raptiiii angiistatis, Uliformibus, subintegris, vel 

 angtistissiine rimatis; ciliis plerumque binis, subaequilongis, articu- 

 lafis nee nodosis, siiperne tenerrime papulosis. Spori parvi. 



Hab. : Bamboo Zone, 9,000 ft., epiphytic ; No. 3764. 



The comparatively large densely crowded leaves give the stems a 

 robust appearance, and in this as well as in structural details it is a 

 markedly distinct species. A. promontorii (C. M.) Dixon has much 

 tiarrower, smaller leaves, a longer nerve, acute lid. etc.
