Malpighiacea.] malpighiacEjE. 49 



superior radicle. — Trees, shrubs, or climbers, rarely herbs. Leaves opposite 

 or rarely alternate, usually entire. Stipules usually small and deciduous. In- 

 florescence various. 



A considerable Order, almost confined to the tropics, chiefly American, with a few Asiatic 

 or African species. 



1. HIPTAGE, Gsertn. 



Sepals 5, with one large gland between two of them at the base. Stamens 

 10, unequal, incurved. Style simple. Ovary 3-lobed. Fruit separating into 

 3 or 2 carpels, each with 3 wings, the central one elongated, with a short 

 crest on the back. — Tall climbers. Leaves opposite. 



A small genus, confined to the tropical regions of the Old World. 



1. H. Madablota, Gartn.; Walp. Rep. v. 294; Wight, Illustr. t. 50. 

 A tall woody climber, glabrous, except the young shoots and inflorescences, 

 which are hoary with a closely appressed pubescence. Leaves oval-oblong, 

 acuminate, 3, 4, or rarely 5 in. long, narrowed into a very short petiole, 

 coriaceous and often shining above. Flowers white, yellowish at the base of 

 the upper petal, in axillary racemes, usually forming a terminal leafy panicle. 

 Pedicels about f in. Sepals obtuse, 3 or 4 lines long. Petals longer, re- 

 flexed, fringed on the margin. Wings of the carpels oblong, the inner one 

 erect, \\ in. long, the outer ones shorter, narrow, and spreading. 



In the Happy Valley, festooning the trees, more rare on rocks on Mount Gough, Cham- 

 pion. Widely distributed over the greater part of tropical Asia. The H. obtusifolia, Roxb., 

 Fl. Ind. ii. 369, is a nearly allied but apparently distinct species, introduced into the Calcutta 

 Garden from S. China, but not as yet found in Hongkong. 



Order XXIV. AURANTIACEiE. 



Sepals 3 to 5, usually united in a short toothed or lobed calyx. Petals 3 

 to 5, inserted on the outside of a hypogynous disk, slightly imbricate in the 

 bud. Stamens twice as many, or in a few genera indefinite, inserted out- 

 side the disk. Filaments often flattened, and sometimes united at the base. 

 Anthers versatile. Ovary entire, of 1 or more cells, with 1, 2, or more, usually 

 pendulous ovules in each. Style simple, with an entire or slightly lobed 

 thickish stigma. Fruit entire, indehiscent, juicy or pulpy, the cells occasion- 

 ally separable from the thickened rind. Seeds attached to the axis, the raphe 

 and chalaza usually prominent, without albumen. Cotyledons thick and fleshy. 

 Eadicle short. — Trees or shrubs, usually glabrous, and filled everywhere with 

 little glands or receptacles of volatile oil. Leaves alternate, pinnate or simple 

 and otherwise entire. Flowers axillary or terminal, solitary or in cymes or 

 panicles, usually white and fragrant. 



An Order not very numerous in species, almost limited to tropical Asia, with a few African 

 or N. Australian species. 



Leaves pinnate. Inflorescence terminal. Ovules usually 2 in each cell, 

 superposed. Style more or less deciduous. 

 Flowers corymbose. Petals narrow, erect at the base. (Ovary 2-celled) 1. Murraya. 

 Flowers paniculate. Petals short, concave. (Ovary 5-celled) ... 2. Clausena.
