Zygopetalum Lindeniae Rolfe, supra. 
enezuela appears to be rich in novelties. Within a comparatively short 
period hâve appeared Maxillaria longisepala , Zygopetalum Jorisianum , 
Peristeria aspersa , and now we hâve another, a really fine and very 
distinct species, to record. It is a Zygopetalum, discovered by M. Bungeroth, 
and by him sent to Messrs Linden, L^Horticulture Internationale, Parc 
Léopold, Brussels. It flowered in that establishment three years ago. There 
is a small stock of plants, which are now becoming properly established, 
and promise to flower during the coming season. 
In habit and general character it bears considérable resemblance to 
Zygopetalum rostratum , yet it belongs to a different section of the genus, for 
it has no trace of the long rostrate anther of the section Zygosepalum , while 
the crest is also totally different. In fact it has the large fleshy crest and other 
characters of Euzygopetalum , to which section it undoubtedly belongs. The 
other sections with solitary flowered scapes are quite out of the question. I find 
no species with which it is strictly comparable. In habit it resembles Z. San- 
derianum , but in no other character, while Z. rostratum , which it undoubtedly 
much resembles in other respects, has totally different sectional characters. 
It must therefore be considered a very distinct species. 
The rhizome creeps upon the branches of the trees, emitting small pseudo- 
bulbs at short intervals, which are ovate-oblong in shape, somewhat compressed, 
and bear two lanceolate acuminate leaves about 6 inches long. The scapes 
are a little shorter than the leaves, and bear two or three large flowers. The
