notes of collectors, Dipodiwm pictum and D. paludosum 
start in the ground, and grow up against the trunks of 
trees; the former to a height of at least seven feet. 
Whether in very open woods, or otherwise, we have not 
been able to find out. 
D. pictum was cultivated at Chatsworth by Paxton 
forty-five years ago, and he states that it was attached toa 
block of wood with a little sphagnum, and was suspended 
in the Orchid House, where it grew rapidly, and flowered 
in September and October. At Kew it is grown attached 
to a stump, in a pot, and the plant from which the drawing 
was made is now nearly two feet high. - 
Brown does not explain why he chose the name Dipodiun, 
literally, two-footed; but there is little doubt it had re- 
ference to the two stalks of the pollinia, not to the 
two small lateral lobes of the lip, as explained by some 
writers, 
Descr—A_ perennial, herbaceous plant. Stems weak, 
attaching themselves to the trunks of trees, sometimes as 
much as seven feet long. Leaves sheathing, closely dis- 
tichous, equitant, lnear-lanceolate, six to twelve inches 
long, acute, three-ribbed, with thinner, intermediate nerves, 
sheathing part and about two inches above persistent, the 
rest of the leaf disarticulating in a truncate manner. 
Inflorescence axillary, simple or slightly branched, many- 
flowered, eighteen inches to two feet long; peduncle about 
as long as the flowering part, furnished with a few small, 
seale-like bracts. Raceme or panicle loose; pedicels, in- 
cluding ovary, about an inch long. Flowers coarsely 
blotched with crimson on a pale ground, about two 
inches in diameter. Sepals and petals similar, oblong- 
obovate or lanceolate, obtuse, nine to twelve lines long. 
Tip erect, adnate to the base of the column, as long as the 
sepals, three-lobed ; lateral lobes very small and tooth- 
like ; intermediate lobe large, obovate, rounded at the tip, 
- narrowed towards the base, densely clothed with coarse 
hairs on the upper surface at the base, in the terminal 
half, and along the middle. Pollinia two, separately 
stalked on the large gland; stalks shortly produced behind 
above the point of attachment of the pollinia.—W. B. H.
