that they are hardly distinguishable by a passer-by. The 
tube of the stamens stands back aloof from the corolla, and 
of the latter the two dorsal petals are quite free down to 
their base. . 
171. DENDROBIUM Cambridgeanum ; (Paxton’s Mag. Bot. vi. 265.) cauli- 
bus pendulis medio incrassatis, foliis ovalibus acutissimis, pedunculis 
bifloris, petalis lanceolatis sepalis latioribus, labello cucullato rotundato 
indiviso supra piloso. 
This plant is only known to me from the figure in Mr. 
Paxton’s Magazine of Botany. It is said to be a native of 
the Khoseea hills of India, whence it was brought to Chats- 
worth by Mr. J. Gibson in 1837; it was found at an eleva- 
tion of 4000 feet, attaching itself to rocks and trees. It is a 
beautiful species, with large rich yellow flowers, having a 
deep purple stain in the middle of the lip; but seems very 
near D. Paxtoni and chrysanthum. 
172. NIPHBA oblonga. : 
Among some extremely fine herbaceous plants sent to the 
Horticultural Society from Guatemala by Mr. Hartweg, is 
one with a dwarf stem, hairy, fleshy, oblong serrated leaves, 
like those of a Gloxinia, and bearing a cluster of large snow- 
white flowers at the summit of the stem, which is undivided. 
It proves to be a new Gesneraceous genus, differing from all 
those in Gesneracee proper in having the rotate corolla of a 
Ramonda, and from Gloxinia, to which it approaches most 
nearly, in the want of perigynous glands, and of a gibbosity 
at the base of the corolla. It will be figured shortly in this 
work ; in the meanwhile the following short character will 
sufficiently define the genus. 
NIPHAA. Calyx superus eequalis S-partitus. Corolla rotata, laciniis 
subeequalibus, duabus superioribus pauld minoribus. Stamina 4 fertilia 
subsequalia, quintum carnosum deforme. Glandule perigyne 0. 
Stigma simplex.—- Sp. 1. Nipheea oblonga. Hirsuta, simplex, foliis 
oblongis, cordatis, dentatis, Tugosis. Flores candidi, axillares termina- 
lisque, cernui.
