Cult. These pretty radicant shrubs will thrive well in a mix- 

 ture of loam and vegetable mould, and ripened cuttings will root 

 freely in sand under a hand-glass, in a moist heat. 



ORDER XLIII. HIPPOCRATEA'CEjE (plants agreeing 

 with Hippocratea in important characters). H. B. et Kunth, 

 nov. gen. amer. 5. p. 135. D. C. prod. 1. p. 567. Hippocra- 

 ticeae, Juss. in ann. du. mus. 18. p. 486. 



Calyx of 5 (f. 105. a.), rarely of 4 or 6 sepals, small, and 

 joined to the middle, permanent. Petals equal in number to the 

 sepals (f. 105. &.), equal, somewhat imbricate in aestivation. Disk 

 occupying the bottom of the calyx, expanded between the petals 

 and the stamens. Stamens 3 (f. 105. c.), rarely 5 or 10 ; filaments 

 free at the apex, dilated at the base (f. 105. c.). Anthers (ex 

 Kunth) 1 -celled, bursting transversely at the apex or 2-4 celled 

 at the base. Ovary hidden within the urceolus or staminiferous 

 tube, trigonal, free. Style 1, crowned by 1-3 stigmas. Fruit 

 sometimes of 3 samara-like carpels, sometimes baccate, 1 -3-cell- 

 ed. Seeds in each cell usually numerous, fixed by pairs to the 

 central axis, erect, exalbuminous, often solitary from abortion. 

 Embryo straight, with an inferior radicle pointing to the base, 

 and flat, elliptic, oblong, fleshy cotyledons. Arborescent or 

 climbing shrubs, usually smooth, with opposite, entire, toothed, 

 feather-nerved, rather coriaceous, stipulate leaves, and axillary 

 corymbs or fascicles of small, inelegant flowers. According to 

 Jussieu, this order is allied to Acer'mece in the ternary number of 

 the stamens. It differs from all the foregoing orders in the sin- 

 gular form of the disk or urceolus, which is either separate from 

 the stamens or formed from the cohesion of the filaments. 

 Synopsis of the Genera, 



1 HIPPOCRATE'A. Petals foveate at the apex. Stamens 3 ; 

 anthers 1-celled, opening transversely at the apex. Carpels 3, 

 samara-like, or only 1-2 from abortion, 2-valved. Seeds winged 

 downwards.

 the outside of the stamens. Stamens 3 ; anthers 2-celled. Cap- 

 sule 3-celled ; cells many-seeded.

 lus between the petals and pistillum. Stamens 3 ; anthers adnate, 

 2-celled. Berry roundish, 3-celled, many-seeded. 



4 CALY'PSO. Calyx 5-parted. Petals 5, with the urceolus 

 expanded between the petals and stamens. Stamens 3 ; anthers
