DESCRIPTIVE LIST OF NEW PLANTS. 09 
Ranunculaceye. —Polyandria Di Pentagima. 
Pceonia Wittmanniana. A more remarkable acquisition than 
a yellow pseony, not a pale straw-coloured species,*which is only 
a spoiled white, but a true yellow flowered plant, does not often 
occur. It was sent to the garden of the Horticultural Society in 
October 1842, by M. N. de Hartwiss, the Director of the Nikita 
Garden, in the Crimea, to whom it was sent by Count M. 
Worontzoff, from Abcliaria. The species has much the appealance 
of Pceonia cretica, is quite hardy, grows where any other pseony 
will grow, and flowers in May. At present we believe that the 
plant in the garden of the Horticultural Society is unique in this 
country. We understand that twenty-five guineas was demanded 
for a single plant of it in one of the great continental nurseries. 
The Mr. Whittmann after whom it is named was, we believe, a 
traveller in the Taurian Caucasus, and afterwards gardener at 
Odessa.— Bot. Beg. 9—46. 
BignoniaceyE. —Didynarkia Angiospermia. 
Adenocalymna comosum. A very beautiful stove - dimoer, 
forming part of a highly natural group of the old and very ex¬ 
tensive genus Bynonia, inhabiting Brazil and Guiana. The species 
makes a fine appearance with its copious flower-buds, which look 
like a large cluster of hops in September and October, and as soon 
as the bracteas fall the conspicuous yellow flowers burst forth. 
They are very large, trumpet-shaped, having a wide spreading 
limb, which is five lobed. It was sent to the Royal Gardens, 
Kew, in 1841, from Rio, by J. Lynd, Esq.— Bot. Mag. 4210. 
Verbenacejs. —Diandria Monogynia. 
Stachytarpheta aristata. This fine suffruticose plant was de¬ 
tected in South America, and probably at Santa Martha, by Yon 
Rohr, and has been sent from thence by Mr. Purdie to the Royal 
Gardens, Kew, where t in a moist stove, it produced its handsome 
dense spikes of extremely rich deep, almost black, purple flower s, 
in October 1845. These flowers begin to expand below, and con¬ 
tinue opening upwards in succession, throughout the whole of the 
elongated spike. No species of this genus yet cultivated is com¬ 
parable to this for richness of colour.— Bot. Mag. 4211. 
Gesneriace^e. —Didynamia Angiospermia. 
Sinningia velutina. This is the handsomest of the genus
