DESCRIPTIVE LIST OE NEW PLANTS. 
last July with the following note : “ It flowers very freely, with 
the habit of Iris ochroleuca , and grows as tall.” 
Possibly it is merely an Indian form of that species ; but, if it 
be so, it presents points of distinction which render it at least a 
well-marked variety. 
It differs from I. ochroleuca in the sepals and petals, being 
more lanceolate and wavy at the edge, and in its bright golden- 
yellow colour. In the former respect, it is more like I. halo- 
phila , but the flowers are much larger, and the base of the sepals 
not more than half as wide. It will be an acceptable addition to 
the list of showy, hardy perennials.— Bot. Reg. 59-47. 
Tritonia aurea (Pappe). This beautiful plant is a native of 
Cafiraria, whence it was brought by Mr. James Backhouse, the 
eminent nurseryman at York. He informs us, it is the Tritonia 
aurea of Mr. Pappe, who, however, does not appear to have pub¬ 
lished any account of it. It is a very fine thing, remarkable for 
the rich apricot-colour of its large Ixia-like flowers, and for the 
abundance with which they are produced. We are unacquainted 
with the foliage and natural habits of the species, but we pre¬ 
sume that it resembles the African Gladioles in manner of growth, 
and in the treatment which it demands, except that, as it is a 
native of the northern districts of the Cape colony, it may be 
expected to be more tender than many of the Irids from the same 
colony.— Bot. Reg. 61-57. 
Ranunculace^e. —Polyandria Trigynia. 
Aquilegia leptoceras (Fischer and Meyer). This very pretty 
plant has been raised in the garden of the Horticultural Society 
from seed, received from Dr. Fischer in 1846, and is thus de¬ 
scribed in the Society’s Journal: 
“ A dwarf herbaceous plant, not growing more than nine inches 
high, with slender, purplish-green stems, thinly coated with scat¬ 
tered hairs. The leaflets of the triternate leaves are wedge- 
shaped, rounded, with about three lobes at the end. Each stem 
bears one or two flowers, on slender pedicles, rather more than 
two inches long. The flowers are bright violet, with the tips of 
the sepals greenish, and of the short petals a clear, bright straw- 
colour. It is a native of Siberia, beyond the Lake Baical, ac¬ 
cording to Messrs. Fischer and Meyer, who distinguish it from
