1 3 0 ANHALS OF THE EOTAL BOTANIC GAEDEN, CALCÜTTi.
abstract of a paper read at tho Oxford meeting of the British Asseciation, 1894, published
ill tlie Scottish Geographical Magazine, Voh X, p. 635, by Lieutenant-Colonel
II. H. Goclwin-Austen, had been mentioned as possessing tlioros at the nodes of the
culms. Such a bamboo was found; its spines were sliort on the upper pai-t of the
culms, and on the lower part were replaced by long, regular, aerial roots. It proved to
be Arunimaria Onjjithmna, Munro. With these two were also found flowering spacimens
of Ariindiimria aristaia, Gamble. Paiiilmgi is a very interesting species, whose exact
position it is difficult to locate. Tho specimens received are all apparently from leafless
culms and boar no trace of spiaos; otherwise it would come next to A. Griffithiana, from
which it markedly diflers in having diflerent culm-sheaths, larger leaves, longer spikclets,
nud no hairs to the tips of the anthers. In the capillary pedicels with glandulär bases
it resembles A. WigUianit and A. flonbuiida, while in the structure of the flowers it
comes near to A. racemosa. But on the whole its nearest relation seems to be A.'
Onßliiana, and if, as is surmised to be the real case, it bears flowers on leafy branches
and spinous nodes, it will come next to it in tho analysis, differing in the characters
mentioned.

main vein narrow, pale, shining, pubescent above, secondaiy veins 6 pairs, intermediate

I am indebted for specimens of this species to Mr. J, W, Oliver, Conservator of
Forests, who found it in February 1894. It comes near to Anmdimria. callom, Munro,
bat is quite distinct from that species. It is called Maitut by the Shans.

This mast be a very pretty graceful species. J, W, OKver w r i t e s T h e bamboo
" is called locally Wapgaian. It is found in fairly moist deciduous forest. It grows iu
" patches, generally occupying dry ravines. The flowering appears to be general, and
" the ground and imdergrowth near the flowering patches were covered with a dense
" layer"of pollen dust." The striped authors are very characteristic even in dry specimens.
It belongs to section II, between Nos. 12 and 13—" Fertile flowers 3 to 4,
" Anthers obtuse, keel of palea not ciliate," Large quantities of the seed have been collected
and distributed, so the species is likely soon to be well known. The absence of
oilias to the keels of the palea and the small leaves ally it io B. rohjmorplm, but the
one-sided spikes and the quite different calm-sheaths distinguish it at once,
