limbo basi squama transversa aucto. D. panduriforme, var. serpens, Нож, f. Fl. Brit.

Нав.--Рввак ; Kunstler (Ге, in Herb. Calcutta). 
Stem 2—3 ft., pendulous, green, internodes channelled and more or less twisted. 
Leaves not seen. Racemes 14 in., about 6—8-Я4.; peduncles short and rachis red-brown ; 
pedicels with ovary about } in.; bracts very small, ovate, acute, Sepals and petals 
spreading, sub-acute, 5-nerved ; mentum nearly straight, obtuse. Lip with the blade 
oblong, cordate above and below, slightly constricted in the middle, 
In the Flora of British India, I have recorded: this plant as a variety of D. panduriferum, adding 
that it may be Reichenbach’s D. tonopws. A further examination of the drawing convinces me that 
it cannot be either the one or the other. From D. panduriferum it differs in the short pedicels, broadly 
obovate 5-nerved petals, much shorter mentum, and above all in the form of the lip, the blade of 
which is more oblong (not deeply constricted with auricle-like side-lobes), and obcordate midlobe 
and the claw is not even twice the length of the blade. .

DENDROBIUM (Pedilonum) TROP&OLIFLORUM, Hook. f. 
D. tropeoliforum ; caule elongato flexuoso superne incrassato apicem versus pauci- 
foliato, folis lineari-oblongis acutis, racemo subterminali plurifloro breviter peduneulato, 
sepalis triangulari-ovatis acutis, petalisque obovato-rotundatis acutis atro-purpureis, 
mento sepalis planis longiore cylindraceo obtuso aureo, labelli ungue elongato flavo

Нав.--Ревак, Kunstler (Ic, in Herb, Hort, Calcutta), 
Stem 1 ft., incurved, slender below, tuberous at the base; roots fibrous; internodes 
Ҙ-І in. grooved, Leaves 2% by $ in. Raceme 1—9 in., rachis slender, pink; bracts 
minute; pedicels with ovary $ in.; flowers 1 in. Sepals and petals 1—1 in. long, 
dark red-purple; mentum four times as long as the sepals, nearly straight, broad, slightly 
undulate, obtuse. Zip small, narrow, about as long as the sepals, claw gradually dilated 
into the short lateral lobes, between which is the large semilunar callus, suddenly 
contracted -into the obovate-oblong apiculate limb. ae | 
A very peculiar species, with flowers a good deal like those of Tropaolum pentaphyllum. 
I have seen no specimen, and have consequently described it from the drawing, which is inscribed 
“in H.B.C. Fl. 30-8-82, from Malaya, Perak, sent by Herr Kunstler,” to which Mr. Brace (then 
keeper of the Herbarium) bas added in a note, “the sides of the claw of the lip adhere to the 
sides of the mentum,” which they do more or less in other species of the section Pedilonum, `
