DESCRIPTIVE LIST OF NEW PLANTS. 
high mountains in Columbia, whence we have copious native 
specimens, not only sent by Mr. Lobb, but by Colonel Hale, who 
gives the elevation at Lloa, 9000 feet above the level of the sea. 
It is a twining succulent annual, with peltate leaves, on long 
slender, cirrhiform petioles. The flowers are solitary on axillary 
peduncles; the calyx is dull brick red, terminating behind in a 
long, nearly straight, subulate spur, green at the tip ; the petals 
are cuneate, orange, all toothed and fringed, the fringe and veins 
red; the two upper petals small and sessile; three lower, the 
largest and unguiculate. 
Treated as the T. majus and minus there is every reason to 
believe that it will prove hardy. It flowers through the summer 
months.— Bot. Mag. 4385. 
PoLEMONiACEiE.— Pentandria Monogynia. 
Cantua pyrifolia (Jussieu). Of all the Polemoniacece, and 
many of them it must be acknowledged are very handsome, some 
species of the present genus Cantua are pre-eminently beautiful. 
We have now the pleasure of announcing a species reared in this 
country for the first time, by Messrs. Yeitch and Son, from seeds 
sent by their collector Mr. William Lobb, from Peru. This is, 
however, by no means the most showy of the Cantuas. G. querci- 
folia has pure white flowers, nestled among leaves as large as 
those of our oaks; and the C. buxifolia has deep rose-coloured 
blossoms, full four inches long. C. pyrifolia is, however, liable 
to vary. The present plant is a branching shrub, with scattered 
shortly-petiolated leaves, varying much in outline and size. 
Corymb terminal, compound. Flowers rather numerous, compact. 
Pedicles half an inch or more long, calyx cylindrical, ovate, green, 
tinged with brown, generally two-lipped; one lip has two, the 
other three ciliated teeth. Corolla funnel-shaped, curved, yel¬ 
lowish-white, or dark cream-coloured; tube longer than the 
calyx; limb nearly erect, of five, broadly oval, or obovate 
segments. Stamens nearly twice as long as the corolla.— Bot. 
Mag., 4386.

Achimenes, vars. Four hybrids raised by Messrs. Backhouse, 
Nurserymen, of York, with whom they flowered In August, 1847.
