Descriptive Notes on Pap'mn Plants, 
ours. The isolation of a Banksia beyond Australia, while plants of 
this genus reach neither New Caledonia nor New Zealand, remains 
remarkable. 
ORCHIDEZE. 
Dendrobium Macfarlanei. 
(Sect. Aporum.) 
Glabrous; stems strongly compressed; leaves distichous^ broad- or 
lanceolate-linear y straight, acute, with an egxiitant base, their edge 
directed towards the stem; peduncles none or exceedingly short; 
pedicels solitary or two together; flowers small, pale; outer sepals about 
half as long as the pouch and the lip, semilanceolar, broader and longer 
than the inner sepals ; labellum with short lateral lobes and a larger 
papillous-thickened end-lobe. 
On the Baxter-River ; Rev, S. Macfarlane. 
Stems, so far as known, about one foot high, leafy to the summit, 
attenuated at the base, and probably not from pseudo-bulbs, each portion 
between the dark-brownish joints about an inch long and two lines 
vride, shining, smooth, yellowish, almost concealed by the vaginal 
persistent portion of a leaf; blade of the leaves when well developed 
inches long and as many lines broad, acute, thickly ohartaceous, 
finely streaked, by basal diagonal fracture deciduous. Bracts short, 
crowded around the base of the pedicel; their rigid nerves resisting 
decay. Pedicels almost capillary, J of an inch or less long. Flowers in 
a dry state pale yellow, in a fresh state probably white. Outer sepals 
about 2"' long ; the upper one slightly narrower than the lower ones ; 
the inner sepals much narrower ; spurlike portion of the flowers nearly 
A" long; labellum seen only in a shrivelled state; its lower portion 
seemingly not very bi*oad. Pollinia 4, cuneate-ovate, longitudinal, 
coherent in two pairs. Fruit unknown. The leaves are longer than 
those of D. micranthum (Lindl. Contrib. Orchid. 3) and the inner 
sepals not several times shorter than the outer ones. Unlike D, Serra 
(Miq. FI. Ind. Bat. iii. 629; Aporum Serra, Lindl. in Wall. Catalog. 
2021), the stems are towards the summit not hare of leaves. Again, in 
D.sinuatum (G. Reichenb. in Walp. Annal. Bot. Syst. vi. 280) the leaves 
are broader, more approximate, and their persistent basal part leaves 
tooth-like prominences; the same distinctive notes hold good for D. 
anceps (Roxb. Flor. Indie, iii. 487), besides the shortness of the leaves 
of the latter species.
