biennial, and, therefore, that by seeds will be the most satisfactory 
mode of multiplying the species.— Brit. FI. Gard. 167. 
POLEMONIACEiE. 
Leptosiphon densiflorus, Thick-flowered Slender-tube.—In its 
general appearance before flowering, this is very like the L. androsa- 
ceus (noticed Hort. Reg. p. 467 ;) its corolla, however, is three times 
the size ofandrosaceus, its colours vary in the same manner from pur¬ 
ple to blue and white. It flowers in October and November, if sown 
in the Spring ; and in April and May, if sown in the Autumn ; but 
would hardly survive a severe winter. Its seeds are produced in very 
small quantities, so that, being an annual, it is likely to remain for 
some years a very rare plant.— Bot. Reg. 1725. 
CACTEAL 
Opuntia monocantka, One-spined Opuntia.—This species is said 
to be a native of the hotter parts of South America.— Bot. Reg. 1726. 
SOLANEjE. 
Nirembergia calycina, Large-flowered Nierembergia_This spe¬ 
cies was discovered by Mr. Tweedie on the Uraguay River, and who 
sent seeds to our gardens, and dried specimens to our collections. 
From the former, plants were raised in the Glasgow Botanic Garden, 
where they flowered in a warm situation in the greenhouse.— Ibid. 
Nierembergia atkinsiana, Mr. Atkin’s clove scented Nierem¬ 
bergia.—This hybrid was raised by Mr. Atkin’s Nurseryman, Nor¬ 
thampton, between N. phoenicea (violacea) and N. nyctaginiflora. 
In habit it is much like the former, but the flowers are nearly inter¬ 
mediate between those of the two parents. The plant will prove a 
ureal ornament in the flower border, as it blossoms most abundantly, 
and is as hardy as the nyctaginiflora. It is readily increased by cut¬ 
tings. The flowers, especially in the evening, diffuse an agreeable 
fragrance, resembling that of the clove pink.— Brit : FI. Gar. 268.

HiEMODO RACEME. 
Anigozanthos manglesii. —This singularly beautiful species of 
Anigozanthos was raised in the garden at Whitmore Lodge, Berk¬ 
shire, the seat of Robt. Mangles, Esq. from seeds brought from Swan 
River by Sir James Stirling, the enterprising governor of that colony, 
by whom they had been presented to Mr. Mangles. It thrives well 
if planted out in a border composed of equal parts of maiden loam, 
leaf mould, and bog earth, with a slight mixture of pounded chalk ; 
a cold frame will be a sufficient protection in winter. It is easily 
propagated by offsets.— Brit. FI. Gard. 265.
