1. Ipomea ritbro-cterulea, Reddish-blue Ipomea. Pentaudria, Monogynia. 

 Convolvulacea;. Of the genus Ipomea, as distinguished from Convolvulus, 

 no less than 165 species are described by Roemur and ScnuLTES. The spe- 

 cies which compose it are chiefly inhabitants of the tropics, and remarkable 

 for the beauty of their flowers, which, though they be individually short-lived, 

 are succeeded so rapidly by others, that there are few more showy ornaments 

 of the forests in warm countries, or of the stoves in our own. One species, 

 I. Jalapa, yields the jalap of the shops; whilst another, the I. Batatas, or 

 Sweet Potatoe, is an important article of food in the tropical countries, as the 

 Potatoe is in Europe. The present species, I. rubro carulea, is grown in the 

 stoves of John Allcard, Esq. and Miss Loxley, of Stratford-Green, Essex. 

 Seeds of it were collected in Mexico, and received in this country by J. D. 

 Powles, Esq. of Stamford-Hill, who liberally distributed them. Flower, in 

 bud, white, with the limb of a rich lake red, which, when fully expanded, 

 becomes of a fine purplish blue ; the diameter of the corolla is about four 

 inches, and altogether the flower is exceedingly handsome, meriting a place 

 in every collection of stove plants. Culture: increased by cuttings or seeds. 

 Soil : rich sandy loam. Ipomea, from Ips, bindweed ; and homois, similar. 



2. F.pidtndrum nocturnum, Night-smelling Epidendrum. Gynandria, Mo- 

 nandria. Orchideae. This plant is a native of the West Indies, growing in 

 this country in the Liverpool and Glasgow Botanic Gardens. The flowers are 

 of a pale greenish yellow, uninteresting in appearance; they are scentless 

 during the day, but at night yield a very powerful odour, resembling that of 

 the White Lily. Epidendrum, from Epi, upon ; and ttendron, a tree — growing 

 upon trees. 



3. Onupordium Arabicum, Arabian Cotton Thistle. Syngenesia, Squall's. 

 CompusitiL'. A native of Arabia, also of the warmer parts of Europe. A 

 plant was grown by Mr. Mackay, at the Dublin College liotauic Garden, ten 

 bet high s raised from seeds sent in 1832 from Buenos Ayres. It is a hardy 

 bienuial. Flowers: terminal, solitary, purple. Culture: increased by seeds; 

 common, rich garden soil. Onopordium, from Ono. ass; and pcrdo, effects. 



1 Ceroptgia l.ushii, Mr. Lush's Ceropegia. Pentandria, Digynia. Ascle- 

 pi d—b This plant was sent from Bombay to the Edinburgh Botanic Garden, 

 where it flowered in October 1833. Flowers: yellow green, tinged with purple; 

 uninteresting. Ceropegia, from Keropegion, a caudelabrum, or lamp stand, 

 referring to the peculiar shape of the flowers.
