the points of distinction between the two species are so nu- 
merous and obvious, that itis not necessary to contrast them. 
The name of Martiana, which I have given to the species, 
is designed, 1 need scarcely say, to compliment the illustrious 
Professor of Botany at Munich. Mrs. Withers has prepared 
a figure which will appear in an early number of ‘The Orchi- 
dacew of Mexico and Guatemala.” 
For the foregoing note I am indebted to Mr. Bateman. 
110. DENDROBIUM revolutum ; caulibus obtusê ancipitibus, foliis ovato- 
oblongis obtusis apice obliquis emarginatis basi subcarinatis, floribus so- 
litariis oppositifoliis, sepalis petalisque acutissimis revolutis, labello car- . 
noso convexo obtuso subtrilobo aut rhombeo per medium exarato (s. la- 
mellis duabus inflexis parallelis instructo) lineis tribus discoloribus. 
A néw species imported from Sincapore, by Mr. Cuming. 
I have received it both from Mr. Barker of Birmingham, 
and Messrs. Loddiges. The flowers are straw-coloured, and 
about the size of those of D. Pierardi, but their lip is fleshy, 
convex, almost lozenge-shaped, and marked with 3 brown 
lines. It is not very pretty, but it is very distinct from any 
previously described. 
111. DENDROBIUM teres; caulibus gracilibus glabris, foliis carnosis tere- 
tibus obtusis, racemo terminali nudo, bracteis coriaceis spathaceis, flori- 
bus semiclausis longé cornutis, sepalis petalisque erectis acuminatis, 
labello cuneato apice truncato serrulato longiüs cuspidato: venis tribus 
pone apicem subcristatis, eolumnâ versus basin dente deflexo aucta. 
Another importation from Sincapore, for which 1 am 
indebted to Messrs. Loddiges. It is a slender plant, with 
the leaves of Vanda teres, and whitish fragrant flowers in 
terminal naked racemes. The lip is deeply stained with 
orange inside near the apex. 
112. DINEMA paleaceum ; pseudobulbis ovalibus compressis monophyllis, 
folis ensiformibus obtusiusculis planis spicà pauciflorà longioribus, 
bracteis lineari-lanceolatis acuminatis paleaceis ovario lentiginoso brevi- 
oribus, floribus secundis, sepalis petalisque lineari-lanceolatis patulis, 
labello petalis equali et subconformi carnoso apice dilatato per medium 
sulcato. 
A Guatemala plant, imported by Mr. Bateman, to whom 
1 am indebted for a specimen. Ít has pale straw,coloured 
flowers, of little beauty, and is only interesting as confirming 
the goodness of the genus Dinema, whose character however 
depends upon the number of pollen straps being 2, not 4 
as in Epidendrum ; the horn-like processes of the column,
