RUTACEJE. 337 



pubescence on young shoots and inflorescence. Leaves ratlier coria- 

 ceous, opposite, crowded on the branches, varying from oblong-lanceo- 

 late to oblong, tapering at the base into a short petiole, more or less 

 obtuse at the apex, entire, sparsely feather-veined, dull, inconspi- 

 cuously but thickly pellucid-punctate, 2 or 2i inches long, from 7 to 

 12 lines wide. Peduncles axillary, longer or shorter than the petiole, 

 sometimes very short (varying from 2 to 5 lines in length), cymosely 

 few-flowered. Pedicels a line long, bracteolate at the base. Flowers 

 a line and a half long, polygamous ; some flowers having large anthers 

 on filaments as long as the petals, and a nearly sessile stigma, while 

 others have a longer style and shorter stamens, with smaller and 

 apparently effete anthers. Calyx puberulent, glandular, four-cleft; 

 the lobes triangular. Petals 4, much longer than the calyx, valvate 

 in aestivation, oblong-lanceolate, with a minute inflexed point, gla- 

 brous, spreading, deciduous. Stamens 8 : filaments glandular-dotted, 

 either filiform and as long as the petals, and with didymous fertile 

 anthers, or only as long as the ovary, and mostly with effete anthers. 

 Disk or gynobase pubescent, four-lobed. Ovary globular, glabrous, 

 four-celled, with 2 amphitropous-ascending ovules in each cell : style 

 rather short, sometimes as long as the ovary, in some truly fertile 

 flowers considerably shorter, terminated by a thickened four-lobed 

 stigma. The staminate flowers examined have a similar, although 

 smaller ovary, which contains one or two apparently well-formed 

 ovules in each cell, and is terminated by a small, four-lobed stigma. 

 Fruit globular, depressed, not in the least pointed, but rather umbili- 

 cate at the summit (the style wholly deciduous), 2 lines in diameter, 

 four-celled, four-seeded (or by abortion two-seeded), loculicidally four- 

 valved from the summit : exocarp rather thin, coriaceous, and glan- 

 dular, as in Zanthoxylum ; endocarp thin, chartaceous. Seed solitary 

 in each cell, ovoid, with a crustaceous, black and shining testa, and a 

 linear lateral hilum; the micropyle superior. Embryo straight, in 

 the axis of fleshy albumen : cotyledons oval, flat : radicle very short.
