DESCRIPTIVE LIST OF NEW PLANTS. 
tigable collector, Mr. Thos. Lobb, who discovered it growing in 
humid parts of mountain woods. 
It is an epiphyte, allied to the iEschynanths, with alternate, 
oblong, acuminate, toothed leaves, fleshy, bright glossy green on 
the upper side, downy beneath and on the edges, about six inches 
long and four broad. The flowers are diandrous, produced in 
dense fascicles at the axils of the leaves, each fascicle containing 
about fifteen flowers ; calyx tubular, smooth, green ; tube of the 
corolla two inches long, of the brightest scarlet; throat wide, 
clothed with hairs; limb imperfectly two-lipped ; upper lip two- 
lobed, lower three-lobed ; stamens exserted; filaments extending 
an inch beyond the tube of the corolla, of a bright purple. 
It is easily cultivated; the same treatment as is given to the 
various species of AEschynanthus suits it well, namely, the tem¬ 
perature of a warm and moist stove, with liberal watering and 
syringing during the period of growth, but in the season of rest 
to be kept nearly dry.— Pax. Mag. Bot. 
PROTEACEiE.— Tetandria Monogynia. 
Isopogon attenuatus (Brown). A native of Lewin’s Land, on 
the southern shores of New Holland, according to Mr. Brown, 
its first discoverer. Allan Cunningham collected it at King 
George’s Sound, Preiss and Drummond at Swan River. The 
latter sent us seeds, which produced flowering plants in the 
spring of 1847. It is a species nearly allied to Isopogon longi- 
folius , but abundantly distinct, growing from two to three feet 
high, with long, scattered, linear- or oblong-spathulate leaves, 
mucronate, much tapering at the base, glabrous, coriaceous, and 
obsoletely three-nerved; and produces a terminal, hemispherical 
capitulum, formed of numerous palish-yellow flowers.— Bot. 
Mag. 4372. 
CACTEiE .'—Icosandria Monogynia. 
Echinocactus chlorophthalmus (Hooker). Whatever reflections 
may be made on the uncouth and grotesque forms of the majority of 
individuals in the Cactus family, it must be conceded of the Echino- 
cactus group especially, that few plants excel them in size and 
beauty of the blossoms. In the present instance, a single flower 
equals or exceeds the height as well as the breadth of the entire
