 species mentioned below is remarkable in having a globose 

 thick caudex or stem ; branches dichotomous ; corolla 

 salver-shaped. They require a well-drained compost of 

 sand and loam. Half-ripened cuttings strike root readily 

 in sand, under a hand glass. But little water is required 

 when tlie plants are not in a growing state.

 elegant genus of stove evergreen climbers. Flowers race- 

 mose, trumpet-shaped, bracteate. Leaves ternate or bi- 

 nate. Stems slender. They i-equire a hot and moist 

 temperature to grow them successfuUy, and tlirive best in 

 a compost of loam and peat. Cuttings will root in sand, if 

 pl'.iced under a bell glass, with bottom heat.

ADENOCABiPUS (from aden, a gland, and karpos, a

 late glands). Okd. Legwrninoitm. Shrubs, with numerous 

 racemes of yellow flowers ; divaricate branches, trifoliate 

 usually aggregate leaves, having petiolar stipulas, and 

 complicated leaflets. All the species are elegant when 

 in flower, and well suited for ornamenting the fronts 

 of shrubberies. Except where otlierwise mentioned, all 

 are hardy. Tliej' thrive best in a mixture of loam, peat, 

 and sand ; and may be readily increased by seeds or layers, 

 or by grafting the rarer on the commoner kinds. Young 

 cuttings will root freely in sand, covered by a hand glass, 

 which should be taken oft' and wiped occasionally. Seeds 

 may be sown in March, the hardy species out of doors, and 

 the others in a cold house.

ADENOFHOItA (from aden, a gland, and phoreoy to

 flower, &c., to Gainpwnula., from which genus Adenopliora 

 ditt'ers in having the style surrounded by a cylindrical 

 gland. Flowei's stalked, drooping, spicate. Leaves broad, 

 stalked, somewhat whorled. They grow best in light rich 

 garden soil, with a warm sunny position, and should be 

 increased by seeds, as dividing the roots is the sure way 

 to lose them. They are easily raised from seeds, which 

 may be sown as soon as ripe, or in spring, in pots placed in 

 a euld frame.
