numerous ; for besides the two African species above named, 

 another was collected by Dr. Behmann near Cape Town ; 



A. Eehmanni, sp. n. (PL XV. figs. 5-8.) Monoicum, pul- 

 vinatum csespitosum ; folia patentia deltoideo-ovata, nervo per- 

 cursa, e cellulis breviter oblongis areolata, pericbsetialia e basi 

 orbiculari convoluta in subulam angustam producta patula ; 

 tbeca globosa ; sporis Isevibus (12); flore masculo gemmiformi 



stipitato. 



Stature that of ^. alternifolium ; stems short, with many short 



branches. 



All these African species agree generally with the oldest known 

 European species, and very similar ones are found in India and 

 Australia; but a great departure is presented by a species sent 

 from Monte Video by M. Gibert, No. 1249. 



A. GiBERTi, sp. n. Monoicum ; caules erecti in c^espites com- 

 pactos aggregati graciles humiles; folia subjulacea imbricata 

 erectiuscula subdeltoideo-ovata brevissime acuminata integer- 

 rima, nervo augusto percursa, cellulis minutis rotundis ubique 

 areolata, perichaetialia late ovata brevi apicnlata convolutacea ; 

 theca globosa tenera ; sporis magnis sublaevibus ; flore masculo 

 gemmiformi in apicibus ramorum. Caulis circiter centimetrum 

 altus cum foliis 0-25 mm. latus. Folia juniora subglauco-viridia, 

 Beniora pallide fusca. 



This, in its julaceous stems, is analogous to those species of 

 Pleicridium like the Australian P. tenuissimwn. 



Trematodon, Bich, 



T. LIOTJLATUS, Behmann^ 22. 

 B^ah, Usaorara Mountains. 



DiCRANUM, Kedio. 



D. (§ IIemicamptlus) dichotomum, Brid. 

 Hah, Kilimanjaro. 



Originally described from Bourbon specimens : it is found also 

 in Madagascar. 



D. (§ Eudtcr.\num) Joh^'stoni, sp. n. Caulis pallide fusco to- 

 mentosns; folia laxa patula apicalia falcata secunda liuearia 

 gensim loriformi-angustata, nervo dorso bicarinato infra summum 

 apicem latiusculum desinente marginibusque e medio ad apicem
