BILLBERGIA Vittata. Linden Cat. 
This pretty plant came to us under the name of Bil/bergia 
vittata, trom Linden, in 1859. It is certainly not the plant of 
that name described by Beer in his review of the Order, nor is — 
it the B. Moreliana vera of Lemaire’s ‘Jardin Fleuriste,’ and 
Paxton’s ‘Flower Garden,’ both of which Beer quotes under 
vittata. It is evidently a near ally of Zil/andsia acaulis, Lindl. 
(Bot. Reg. t. 1157); but as the calyx is distinctly superior, it 
cannot be referred to that genus as characterized in Endlicher. 
Probably it should be referred to Beer’s genus Chryptanthus, of 
which no generic characters have been published by that author. 
It is, no doubt, a native of South America, but we are not 
aware of its exact country. 
Descr. Plant almost stemless. Leaves closely set just above 
SEPTEMBER Ist, 1861.
