10 PROFESSOR LINDLEY'S CONTRIBUTIONS TO 
Hamburg, and another of my. own dated Sept. 1854, in both 
. Which the stigmatic hollow is concealed by a tooth-like elevation 
of its lower edge, a structure also occurring in Thelychiton and 
D. normale; in the Kew plant there was, moreover, a bristle on 
one side of this front tooth, and external to it; but Prof. Reichen- 
bach did not find it in many fresh flowers examined by himself, 
nor does either the bristle or the front tooth occur in the original 
Aclinia. The meaning of these malformations opens a curious 
field of inquiry, to which I hope to address myself on a future 
occasion. 
97. D. LAWANUM ; caule juniore carnoso ascendente folis membra- 
naceis lanceolatis acutis, florido aphyllo vaginis laxis membranaceis 
fere abdito, sepalis petalisque ovatis obtusiusculis, labello paulo majore 
conformi concavo. (Dendrochilum roseum, Dalzell in Hooker's 
Journal, iv. 291.) 
On trees on the Syhadree range of mountains, Dalzell in hb. Stocks

Mr. Dalzell states that in this plant, “across the front of the 
column and below the orifice of the stigmatic cavity, there is a 
small crest terminated on each side by a deeply-coloured horn, 
two- or three-toothed at theapex." This seems as if we had here 
also some monstrous structure ; but Iam unable to refer the plant 
to any of the Eudendrobia, unless indeed D. transparens should 
claim it; and I must add, that there was nothing unusual in the 
column of the only flower I have had an opportunity of dissecting. 
98. D. TETRODON (Н. G. Rchb. in litt.); caulibus floridis tenuibus 
pendulis aphyllis junioribus folis anguste lanceolatis membranaceis 
subobliquis, floribus geminatis, sepalis petalisque lineari-lanceolatis 
acutissimis, mento obsoleto, labello conformi paulo majore et obtusiore, 
clinandrio quadridentato. 
Java, on trees at the foot of M. Salak, Zollinger (11). 
Of this I have a good specimen from Prof. Reichenbach. It 
has the habit of such a plant as D. transparens; and there is a 
slight tendency to the extension of the lateral sepals at the base. 
Can it be a Peloria of D. macrostachyum? I find nothing mon- 
strous in the column.
