220 ANACARDIACEiE. Styphonia. 



2. STYPHONIA. Nutt. mss. 



" Sepals 7-9, colored, concave, with scarious margins, imbricated in seve- 

 ral series, persistent, somewhat similar to the rather imbricated bracteoles at 

 the base. Petals 5, oblong, slightly unguiculate, of the same texture as the 

 sepals, pubescent within near the base, inserted under the margin of the disk. 

 Stamens 5-7. Style short: stigma minute, 3-lobed. Fruit a dry flattened 

 drupe ; the pulp very acid and astringent : nut compressed, bony, 1-celled. 

 Seed solitary, suspended from a funiculus rising from the base of the cell. — 

 Low and much branched submaritime trees. Leaves simple, alternate, thick 

 and coriaceous, persistent. Flowers polygamous, sessile, in terminal con- 

 tracted panicles. Bark exuding small quantities of a very astringent gum- 

 resin." Nutt. 



1. S. integrifolia (Nutt. ! mss.) : " leaves oval, very obtuse at both ends, 

 entire, on short petioles. 



" On the margins of cliffs, &c. near the sea, around St. Diego & St. Bar- 

 bara ; common. — An unsightly tree, about the thickness of a man's arm, 

 branching widely and forming almost impervious thickets, glabrous ; the 

 young leaves and branches minuteljr pubescent. Leaves an inch or more 

 long, three times the length of the petioles, rather prominently veined beneath. 

 Flowers in few-flowered sessile clusters upon the short branches of the pani- 

 cle. Sepals and petals reddish. Drupes the size of a pea, hirsute. — Fruit 

 similar in most respects to that of Rhus § Sumac ; inflorescence somewhat 

 approaching that of Lobadium ; differing from both, particularly in the gra- 

 dual transition from bracts to petals. To this genus apparently belongs Rhus 

 atra, Forst., of New Caledonia, of which I hav&seen an original specimen, 

 but with:)Ut the flowers: the leaves are 3-4 inches long, very thick and rigid, 

 attenuated into short petioles, with very prominent anastomozing pinnate 

 yeins. Rhus mollis, H. B. ^ /f., also evidently belongs to the genus." Nutt. 



2. S. serrata (Nutt. ! mss.) : " leaves oval or ovate, on very short petioles, 

 sharply repand-serrate. 



" With the preceding, from which it differs merely in its leaves, which 

 when young are sharply serrate with small mucronate teeth ; the older leaves 

 are obscurely repand-serrate." Nutt. 



Orper XXXV. AMYRIDACE^. R. Br. 



Flowers perfect, regular. Sepals 4, or rarely 5, small, united at the 

 base, persistent. Petals as many as sepals, hypogynous (or none) : 

 aestivation imbricated. Stamens twice the number of the petals, hy- 

 pogynous, distinct : anthers introrse. Ovary solitary, simple, 1-cell- 

 ed, seated on a thickened disk : stigma capitate, sessile : ovules 2-6, 

 pendulous. Fruit drupaceous, leguminous, or samaroid, glandular, in- 

 dehiscent, 1-2-seeded. Seeds anatropous, destitute of albumen. Em- 

 bryo with a very short radicle, and thick fleshy cotyledons. — Resini- 

 ferous trees or shrubs. Leaves pinnately 3-7-foliolate, opposite, with 

 glandular pellucid dots, mostly destitute of stipules. Flowers panicled. 

 Pericarp covered with granular glands, filled with an aromatic oil.
