DESCRIPTIVE LIST OE NEW PLANTS. 69 
LeguminoSjE. Garden Hybrid. 
Erythrina Bidwillii. This plant was sent me at Spofforth by- 
Mr. Bid will, from Sydney. I am not sure whether it was raised 
by himself or by Mr. Macleay. It is a hybrid production from 
E. herbacea , impregnated by E. cristagalli, and is remarkable 
as being, I believe, the only certain hybrid papilionaceous plant 
we have. It is a very beautiful plant, of intermediate habits; 
its vigorous shoots die down to the root after flowering, and have 
leaves of an intermediate form, approaching in colour and gloss 
rather to those of the Carolina E . herbacea. The flowers are of 
intermediate size and colour; but, like those of E. cristagalli , 
borne by threes at the axils of the leaves as well as on a terminal 
spike, while those of E. herbacea are borne on a leafless spike 
proceeding from the root. I hope to multiply it by cuttings, and 
consider it to be a great acquisition.—W. H.

Irldace^e. Triandria Monogynia. 
Iris setosa (Pall.) This very pretty plant is said by Dr. 
Fischer to inhabit the northern part of Eastern Siberia, along 
the Lena, about Schigansk and Jakutzk, in Kamtschatka, Una- 
laschka, Escholtz’s Bay, Chamisso’s Island, &c. Its root is said 
to be poisonous, but we know not on what authority. It is a 
very hardy herbaceous species, growing from one to two feet in 
height, if planted in any good garden soil and freely supplied 
with water during the growing season, but afterwards, the plants 
should be kept rather dry, as they are very impatient of damp 
or wet during the winter months. The flowers are of medium 
size, bright delicate lilac, striped or veined near the base of each . 
petal with crimson, the claws of the petals are yellow, thickly 
striated with red. It is best increased by seeds treated in the 
usual way, but the young plants will not flower before the second 
year. It was raised in the garden of the Horticultural Society, 
from seeds received from Dr. Fischer, and flowered in May last 
for the first time.— Bot. Reg. 10-47. 
Fabace^e. Diadelphia Becandria. 
Lupinas Ehrenbergia (Bentham). A very pretty, half-hardy
