GLEANINGS AND ORIGINAL MEMORANDA. 
397. Mdiosa uruguexsis. Hooker and Amott. 
A lialf-linrdy 
lianclsome spiny slirub, Tvitli brick-red flowers. Native of the BauJa 
Oriental. Elossoms in June^ July, and August. (Kg. 200.) 
This shrub \\'as originally raised in the garden of the Horticultural Society, from seed 
obtained from Euenos Ayrcs by the Hon. W. F. Strangways ; and first flowered at Chis- 
Mick in June, 1841. Since that time it has been cultivated in the same establishment, 
though scarcely known elsewhere, and proves to be a useful shrub for 
the summer decoration of borders, where it lives and flowers freely 
till the approach of winter. It is about as liardy as the general 
mass of New Holland Acacias. The flowers have a light and 
. elegant appearance, with tlieir reddish or brickdust tint, among 
the finely divided shining delicate foliage. The branches are 
always short, and furnished with little straight spines, each branch 
beai'ing from two to four balls of flowers. The chief horticul- 
tural defect of this plant is that, like other hard-wooded small- 
leaved shrubs, it is rather too thin of leaves, and becomes naked 
at the base when old. When we find a plant like this, of a tropical 
genus, so nearly hardy, we can but entertain a confident opinion 
that tlie countries watered by the River Uruguay deserve to be 
visited bv some horticultural collector. 
398. Cattleya Leopoldi. Ihrt. A beautiful stove 
Epiphyte with brownish yellow spotted flowers, and a 
rich crimson lip. Native of Brazil. 
This is a mere variety of CattUya granulosa, with a most brilliant 
tint of rich purplish crimson in the lip. It is one of the handsomest 
orchids in cultivation, and seems to have readied us tlirough the 
Belgians, the first we heard of it being that it had been exhibited at Brussels by 
Mr. Forkel, gardener to King Leopold at Laeken, 
399. Clematis hexasepala. JDe Candolle. {alias C. hcxupctala 
Forster.) A half-hardy green-flowered twining fragrant plant, belonging 
to the Order of Crowfoots. Native of New Zealand. 
This is a little twining plant, with shining nearly smooth ternate or bitemate leaves, whose petioles twine round any 
small body with which they may come in contact. The leaflets are cordate-ovate, coarsely serrated, and often three-
