 tive of Ceylon. Flowers white ?

Cult. This is a genus of fine broad-leaved trees. They will 

 thrive well in a mixture of loam, sand, and peat, and cuttings, 

 not deprived of their leaves, will root readily in sand, under a 

 hand-glass, in a moderate heat.

 same manner as recommended for Pterospermum,

 brightness of flowers). Lindl. coll. bot. t. 14. D. C. prod. 1. 

 p. 500. 



LIN. SYST. Monadelphia, Polydndria. Flowers umbellate, 

 girded by a many-leaved involucel ; leaflets roundish, ovate, 

 with the 2 outer ones opposite. Calyx of 5 sepals, with 1 brae- 

 tea on the outside of each. Petals 5. Stamens joined into a 

 long tube, 5 sterile, 20 fertile. Ovary 5-celled. Style 1 . Stig- 

 mas 5. Ovulse few in each cell. Elegant trees, with large 

 angular leaves, and drooping umbels of scarlet flowers.

 of the island of Bourbon. Perhaps a species of Dombeya. 



Lime-tree-leaved Astrapaea. Clt. 1824. Tree 10 feet? 



Cult. A. Wallichii is one of the finest plants that ever was 

 introduced into Britain ; when in flower nothing can exceed it 

 in beauty. All the species will grow well in a rich soil or a 

 mixture of loam and peat ; and young cuttings planted in 

 mould, and placed under a hand-glass in heat, will soon strike 

 root. 



f- Uncertain Dombeyacece.

 love for botany induced him, at the desire of the East India 

 Company, to begin a botanical garden and nursery at Calcutta,
