Mr. Gunn (n. 454.)—This is the true 
plant of Labillardiére, whose original spe- 
cimen is from Van Diemen's Land. The 
New Holland state of it, which M. Sieber 
has published, under the name of P. eleag- 
nifolium, and which Mr. Cunningham finds 
in the Blue Mountains, has the corymbs 
with more flowers, and of a smaller size; 
the underside of the leaves, too, is whiter 
and more silvery.

n (n. 458. nod is very near 
B. pilonema of Lab. but in that the 
flower is alway constantly 
lateral), and the filament are naked. 
3. B. variabilis, Hook. 1. c. p. 255. — 
The last collection received from Mr. 
Gunn, so rich in good specimens, ena- 
bles me to correct my ideas respecting 
B. variabilis, and to refer the varieties 
a. and y. to B. tetrandra, Labill., not- 
withstanding the flowers are octandrous. 
The name of variabilis will be confined 
to the var. £., which has the leaves very 
generally dipinnate, the leaflets oblan- 
Ceolate or cuneate, entire or trifid, 
marked with viidi glandular dots. 
_ The branches have two opposite lines of 
hairs. A species nearly allied to this is 
the B. anethifolia of Cunningham’s MSS., 
found by that enterprising Naturalist, on 
the West branches of Hunter’s River, 
and in Wellington Valley; but the stems 
are remarkably angular, the leaflets 
acute, the flowers more numerous on the 
peduncle.

Mr. Gunn (n. 460.) — Discovered by 
Mr. Backhouse, at Meredith River, Swan 
Port, E. coast. This is still more nearly 
allied to P. betulina (Cunn. in Bot. Mag. 
t. 3212.) than is our P. racemosa ; but the 
leaves are decidedly obovate, and the flow- 
ers are not apetalous.

ON THE MEDICINAL PLANT,

Extracted from a Memoir, entitled, " Observations on 
of the Royal College of Physicians, London 
( Read jh the College of Physicians and nt Sago of

(I a already seen some notice of the 
powerful effects of the roots of this plant, 
in our Journals; and on the 19th of the 
present month, Feb. 1836, I had the plea- 
sure of receiving the following letter from 
Dr. Bancroft; accompanied by the pamphlet 
there alluded to; and by specimens of the 
root, with its leaves and flowers, dried with- 
out pressure, but in a sufficiently perfect 
state to enable me to determine the spe- 
cies in the most satisfactory manner.

« My Dear Sir,—I am very sorry that 
indifferent health and a great want of lei- 
sure have so long suspended my commu- 
nication with you, for I have frequently 
wished to lay before you such information 
as seemed to me novel, and which I there- 
fore hoped might prove worthy of your 
attention. I have lately been induced to 
write and publish a memoir on a plant, 
called Daichi, whose botanical his- 
tory had been hitherto unknown :—it is 
found in Quito, near the foot of the great 
volcano of Chimborazo, and is only recently 
come into notice, from its supposed virtues 
as a remedy for that horrible disease, too 
frequent in tropical regions, the Mal de
