AURANTIACE.S:. 123 



Leaves alternate, petiolate, without stipules, lanceolate, subacu- 

 ininate with the apex blunt, attenuated at the base, very glab- 

 rous, nerved, with a pustulose blister in the axil of the under 

 surface of each nerve, about 6 inches long, and 1 broad : petiole 

 plane above. Panicle axillary, solitary, shorter than the leaf: 

 peduncle and its subdivisions compressed, puberulous : flowers 

 greenish-yellow, fragrant, shortly pedicelled. Calyx minute, 

 5-, rarely 4-toothed, externally pubemlous, persistent. Petals 

 5, rarely 4, alternating with the teeth of the calyx, lineari-ob- 

 long, obtuse, externally puberulous, internally marked with 3 

 longitudinal ridges, and villous especially near the base. Sta- 

 mens 5, alternating with, and more than half the length of the 

 petals, spreading ; filaments expanded at the base, towards the 

 apex subulato-compressed : anthers cordate, purpurascent. 

 Ovary placed on a minute annular disk, ovate, puberulous, 1- 

 ovuled : style very short : stigma bifid. Fruit subdrupaceous, 

 (from the thinness of the cortical part,) size of a pigeon's egg, 

 ovoid, mono-pyrene : shell chartaceous : seed solitary. 



I refer this plant with some confidence to the above genus ; 

 although Adr. Jussieu, by whom it was founded, describes the 

 fruit of the only species hitherto known, as a capsule dehiscent 

 at the apex. 



ORDER XXXIII. AURANTIACE^. 



Calyx urceolate or cainpanulate, somewhat adher- 

 ing to the disk, short, 3-5 toothed, marescent. Pe- 

 tals 3-5, broad at the base, free or slightly combined, 

 inserted upon the outside of a hypogynous disk, 

 slightly imbricated at the edges. Stamens equal in 

 number, or some multiple of that of the petals, in- 

 serted upon a hypogynous disk : filaments flattened 

 at the base, sometimes slightly cohering among them- 

 selves : anthers terminal, innate. Ovary many-celled : 

 style 1, terete: stigma thickish, slightly divided. 

 Fruit pulpy, many-celled, with a leathery glandulose 

 valveless indehiscent rind ; cells verticillate, frequent- 

 ly separable without laceration, usually filled with 

 pulp : pulp lodged in innumerable little sacs arising 

 from the sides of the cell. Seeds attached to the 

 axis, l-x, usually pendulous ; raphe and chalaza
