Specimens to all appearance the same come from Mauritius 

 and Madagascar; but as none have been seen in fruit except 

 those from the Cameroons it cannot be decided. The Abyssinian 

 jS. longe-aristatum^ C MiilL, does not appear to differ; B^ 

 capense, C. MiilL, Eehmann 267, seems to be i2. mucronatum^ 

 Beauv., it is found in Natal. Besides these there have been 

 described B, angusti-stipulaceum^ C MiilL, from Comoro ; B. 

 spelunccey ejusd., from Kalunga, Bongo; B. pectinatum, ejn^d,, 

 from Dar Pertit, with the preceding collected by Dr. Schweinfurth; 

 there is also the B. mauritianum, C. MiilL, B. angustifolium^ and 

 B^prcdlongmiiy Schimp., enumerated by Beseherelle from Bourbon, 

 Mauritius, and Comoro. A well-marked species was sent by 

 Dr. Ayres from Mauritius : 



R. Ateesii, sp. n, Caulis pinnatim ramosus sed ssepius 

 longe procerus parce tomentosus ; folia inter se remota pectinatim 

 distichacea ovali acuminata, nervo obscuriore in aristam dimidiam 

 folii Ion gitudinis sequalem excurrente Isevi, margine apicem 

 versus subintegerrima, in ramis denticulata, cellulis omnibus 

 moUibus ovalibus pellucidis areolatisj folia stipuliformia ovata, 

 nervo in subulam sequilougam Isevem excurrente. 



Hah. The Pouce Mountain. 



Dr. Ayres himself noticed that this differed from the other 

 species he had gathered (B. africanuni) in being without the 

 tomeutum. In its areolation it is quite distinct, but it may be 

 really one of the species before mentioned as already described, 

 in which the form of the cells is not stated.
