546 Mr. Miers on some new Brazilian Plants 
Plante (Bras. et Amer. Bor.) rhizocarpæ, radice fibrosd. Caulis erectus, sub- 
dichotomè ramosus, ramis subflexuosis. Folia pauca, sessilia, erecta, brac- 
teiformia, pallida. Inflorescentia terminalis, uniflora. Flores ceteris ma- 
Jores, erecti, ebracteati, purpurascentes. 
1. A. setacea, Nutt. 
On this species I need only remark, in justice to Mr. Nuttall, that he states 
all his materials to have been derived from dried specimens, and that he 
could not distinguish the nature of the stamens. Had he been able to observe 
the plant in its living state, he would no doubt have witnessed the curious 
development of those organs so peculiar to the genus. From all that he had 
noted and recorded of Apteria, there was sufficient ground for concluding 
that my Brazilian plant constituted a distinct genus, and accordingly I had 
named it Stemoptera from the peculiar character of the stamens, although I 
confess that its close approximation to Mr. Nuttall’s plant had forcibly struck 
me. While I was preparing these details, Mr. Brown examined a specimen 
of Apteria setacea in his possession from the original locality, and identified 
my plant with Mr. Nuttall’s genus, of which Mr. Bentham also examined 
another species collected by Hartweg in Mexico; these observations were 
kindly communicated to me, and I was favoured with the sight of a spe- 
cimen, when I could perceive by transmitted light the hollow sacs in the 
perianthium above described, and somewhat similar winglike expansions of 
the filaments. I did not hesitate, therefore, to suppress my generic name and 
substitute for it that of Apteria. 
2. A. lilacina, caule ramoso, foliis plurimis acutis erecto-patentibus, perianthio 
urceolato-tubuloso : laciniis exterioribus 3 lanceolatis acuminatis ; inte- 
rioribus 3 ovatis mucronulatis. Tas. XXXVIII. fig. 5. 
A native of the Serra dos Orgäos, near Rio de Janeiro. 
I have already observed, that in general habit and appearance this plant 
bears much resemblance to the figure Mr. Nuttall has given of his Apteria 
setacea: the singular expansion of the filaments and the swellings in the 
mouth of the perianthium give to Apteria a very distinct character from all 
the related genera. Its flowers are greatly larger than those of Dictyostega or
