284 MOSSES (Gepp). [Schlotheimia 



calyptras flavescent, splittiflg at base into eight regular subtruncate 

 laciiiiae. On branches of XeropJtyta squarroaa Baker (Hb. Welw. 

 No. 1555), often entirely enveloping them, on elevated rocks of the 

 prEesidium, seldom bearing fr., but found with fr. at Barranco de 

 Catete ; April, May, 1857. No. 66. 



This species was previously known to occur in Brazil only ; and the 

 original plant was gathered by Swainson near Rio de Janeiro, according 

 to Hooker (Muse. Exot. t. 128). Hooker's Herbarium, however, 

 affords reason for the belief that the original locality was Bahia. The 

 African plant appears to differ from the Brazilian as redescribed by 

 C. Mueller (Synops. I. p. 761) in the lighter colour (yellowish brown), 

 more laciniate base and less rough (merely scab"ous) apex of the 

 calyptra.

PuNGO Andongo. — A blackish-green, densely csespitose moss, closely 

 enveloping the upper branches of Xerupliijta squarrosa Baker, Hb. 

 Welw. No. 1555 ; common, but very seldom producing fruit owing to 

 the exposed situation it occupies on unsheltered rocks in the fierce 

 heat of the sun ; Pedra de Causambe, within the praesidium ; with fr. 

 in very small quantity, 3 May 1857. No. 53 A few specimens 

 found on a half-dry branch which had fallen from an old tree in the 

 primitive wood called Mata de Pungo, within the praesidium ; with fr. 

 beginning of June 1857. No. 86.

HuiLLA. — Very common ; growing with Braunia arbusculd (No. 32) 

 on old trunks which are bearded with Usnea and Phyacia on the 

 summit of Serra da Xella, where Welwitsch often saw it bearing fruit 

 on a species of Tarchonunthas and other trees ; gathered in a very dry 

 and fragile state with fr. June 1860. No. 19. (The British Museum 

 specimen has no fruit). A very dry and brittle moss with a conical 

 straightly rostrate operculum and hardly any peristome except a very 

 short white membrane ; mingled in tufts of Brautiia arhnHcula (No. 32). 

 but much more slender than that plant ; in company with various 

 Lichens on branches of old trees on the highest parts of Serra da 

 Xella at an elevation of about 4000 ft. ; with fr. June 1860. No. 198. 



GOLUNGO Alto. — Growing with Eriitlirodontium on old trunks, 

 especially of Edicardia lurida, in rocky woody parts of Sobato de 

 Quilombo-Quiacatubia ; with fr. July 1856. No. 144.
