10 ANNALS OF ROYAL BOTANIC.GARDEN, CALCUTTA. 
spur-like mentum. Zip hardly recurved, as long as the sepals spotted with dark-red 
on each side towards the base of the blade, flabellately many-nerved; claw with a 
narrow median canal leading down to the short oblong recurved callus or scale. 
A beautiful species, of which I have seen only the dried flowers accompanying the druwing. 
The latter is inscribed “Larut, Perak, Ie. Hort. Bot. Cale. Fl. 24-9-83." |

DENDROBIUM (Pedilonum) PANDURIFERUM, Hook. f. 
D. panduriferum; caulibus elongatis cylindraceis suleatis, foliis in caulibus junioribus 
lanceolatis acuminatis, racemis in caulibus aphyllis axillaribus brevibus paucifloris, bracteis 
parvis, pedicellis divaricatis, floribus flavis rubro-punctatis, sepalis lateralibus late ovatis 
subacutis, mento in calcar elongatum sepalis multoties longius apicem versus subinflatum 
producto, petalis orbicularibus crenatis multinerviis, labello longissime anguste unguiculato 
limbo panduriforme medio valde constricto lobis lateralibus auriculeformibus, terminali 
late obcordato, disco ad basin loborum lateralium lamella transversa aucto. Hook. f. Flor. 
Brit. Ind, vi. 186. ` 
Нав.—Рево ; at Rangoon, Gilbert (10. in Herb. Hort. Calcutta). 
Stem 2—3 ft, narrowed at the base, no doubt pendulous; internodes 1—11 by 
4 in, green, nodes often rooting; sheaths white, young green and  speckled, 
membranous. Racemes 1—2 in.; bracts small; pedicel with ovary 4 in. and peduncle 
purplish; flower 1 in. long. Sepals and petals yellow or greenish, with red dots along 
the numerous nerves; mentum straight or slightly curved, streaked with red. Lip with 
the claw 3—4 times as long as the dull yellow limb, margins of claw incurved above, 
below connate with the sides of the mentum. Column very short; anther stipitate. 
A remarkable species. The analyses fig. 1, flower, with the lip displaced; 2, petal; 3, lip; 4, column 
and anther; 5, anther—al/ enlarged—are from drawings of my own of some flowers contained in a 
capsule attached to the drawing. The latter is inscribed “ Rangoon, Dom. Gilbert misit; Fl. in Н. B. C. 
19-11-81." It must be very nearly allied to the D. ionopus, Reichb. f. in Gard. Chron. 1882 ii. 
508, from Burma, which has yellow flowers with red blotches and an elongate faleate mentum ; but 
that species is described as having a thick keeled claw of the lip with a flat retrose tooth. The 
latter is a common character of the section Pedilonum, but I found no trace of it in the ‘solitary 
lip of D. panduriferum which I was able to examine. | | к.
