readily recognised by the different form of the corolla, and by its 
glabrous stem and leaves.— Bot. Mag-. 4298. 
AscLEPiADACEiE. —Pentandria JDigynia. 
Marsdenia maculata (Hooker). This has long been cultivated 
in the stove of the Royal Gardens at Kew, as a new asclepiadeous 
plant which had been sent by the late Mr. Lockhart, of Trinidad, 
and we have received flowering plants from Messrs. Lucombe, 
Pince, and Co., of the Exeter Nursery. In 1834 living plants 
were again transmitted to the Royal Gardens by our collector Mr. 
Purdie, from the plain of Santa Martha, New Grenada. It seems 
to be a true Marsdenia , and is remarkable for its large foliage, 
spotted with pale yellow, somewhat like the leaves of Aucuba 
japonica , but with the spots more regular, more equidistant, and 
less confluent. It is a great climber, and flowers readily in June; 
the flowers are of a dark purplish or liver colour, greenish when 
young, and thus the dense umbels have a mottled appearance ; 
their texture is rather fleshy, like those of Hoya.—Bot. Mag.

ScROPHULARiNEiE.-— JDiandria Monogynia. 
Calceolaria amplexicaulis (Sprengel). A handsome and orna¬ 
mental Calceolaria, though except in foliage little differing from 
many other forms of that genus, which have been some time in 
cultivation, and on that account perhaps not likely to become 
a general favorite. It is a native of Peru and Colombia. 
Humboldt met with it upon the banks of the San Pedro, between 
Chillo and Condcoto, at an elevation of from seven to eight 
thousand feet above the level of the sea; Mr. William Lobb at 
Muna, whence he forwarded seeds to Mr. Yeitch, of Exeter, where 
it has flowered; the flowers are deep yellow, produced in a large 
compound corymb. —Bot. Mag. 4300. 
CoNVOLVULACEiE. —Pentandria Monogynia . 
Ipomeea muricata (Gavanilles). A beautiful little species, not 
very aptly named muricata by its first describer (for the base of 
the sepals alone are tubercled), and very inaccurately described 
by most authors in regard to its foliage. The leaves are not 
simple and whorled or fascicled, as they might appear at first
