 terminal pinna, lengthened out at the point, and deeply serrated, 

 and three to four pairs of erecto-patent similar lateral ones, which 

 are Sin. to 4in. long, upwards of iin. broad, equally truncato- 

 cuneate, and the lower ones slightly stalked at the base, tori 

 distant, falling short of both edge and margin. New Caledonia. 

 A very graceful greenhouse species. STN. A. tchizodcm. A. 

 ' aril Mini is but a variety of this, with shortened son and more 

 obtuse venation.

ASSONIA (commemorative of 

 Ignatius de Asso, a distinguished 

 Spanish botanist, who wrote on the 

 plants of Arragon). ORD. Stercu- 

 liacece. This genus is now included by 

 best authorities under Dombeya. Or- 

 namental stove evergreen trees, with 

 undivided leaves, and axillary, bifid, 

 sub-corymbose peduncles. They are 

 of easy culture ; thriving freely in any 

 light rich soil, or a mixture of loam 

 and peat. Young cuttings will root 

 freely in sand, with a brisk bottom 

 heat, if covered by a bell glass. 



A. popnlnea (Poplar-leaved), it. white, 

 disposed in a terminal, bifid corymb ; 

 peduncles scarcely longer than the pe- 

 tioles. June. I. cordate, acuminated, 

 smooth, a little serrated. A. 10ft to 20ft 

 Bourbon, 1820. 



A. yiburnoldea (Viburnum-like). It. 

 white ; peduncles three times longer than 

 the petioles. I. cordate, somewhat acu- 

 minate, crenated, tomentose beneath, as 

 well as younger leaves, h. 10ft. to 20ft 

 Bourbon, 1822. 



ASTAB.TBA (a mythological 

 name : Astarte, the Syrian Venus). 

 ORD. Myrtacece. An ornamental green- 

 house evergreen shrub, requiring a 

 mixture of loam, peat, leaf soil, and 

 sand. Young cuttings root readily in 

 sand under a bell glass in gentle heat. 

 A. tesdcnlarls (bundle-floweredX. Jt. 



white, pedicellate, solitary, axillary. 



May. L opposite, linear, fleshy; when 



young, disposed in axillary fascicles, h. 



6ft to 9ft. West Australia, 1830. 



ATr;TiM^ (from a, not, and 

 stelma, a crown; in reference toth? 

 construction of the fruit). ORD. Com- 

 posites. Greenhouse evergreen shrubs 

 from the Cape of Good Hope. Some 

 species of this genus, which ia no\v 

 generally referred to Helipterum, are 

 very handsome, and thrive well in a 

 mixture of fibrous peat, leaf soil, and 

 sand, with thorough drainage. Fill 

 the pots one-third full of crocks ; water carefully, and 

 only when absolutely necessary ; and place in a situation 

 near the glass, allowing a free admission of air. Seeds 

 should be sown in pots of light, open soil, and placed in a 

 gentle heat; half -ripened cuttings will strike readily in 

 sandy soil with a hand glass placed over them. They arc 

 now but rarely seen under cultivation.
