flowers rather large, polygamous, greenish-yellow. $ Fl Calyx 

 small ; sepals 5, overlapping each other, roundish, blunt. Pe- 

 tals 5, oblong, blunt, glabrous. Stamens 5 : filaments subulate, 

 length of the petals, alternating with them : anthers rather 

 large, oblong. $ Fl- with the calyx, petals, and stamens as in 

 the male : carpella in the ovarian state 5, connate : style (?) : 

 stigma blunt. Carpels (half developed) subglobose, at the apex 

 5-angulari-lobate : seeds minute, 3 in each cell ? 



Although I have stated the stem to be unarmed, it is possi- 

 ble that it may be furnished with prickles when young. I

FL. June. 



A tree about 20 feet in height. Stem erect, armed with nu- 

 merous strong thick spines or prickles : branches spreading, 

 thorny, tomentose at their termination. Leaves situated prin- 

 cipally at the ends of the branches, impari-pinnate, 78 paired ; 

 the leaflets very shortly petiolulated, for the most part opposite, 

 oblongo-lanceolate, blunt, entire, not punctated except along 

 the margin where there is a row of pedicelled dots giving the 

 appearance, when held against the light, of obsolete crenatures, 

 smooth shining above, hairy along the under surface of the 

 nerves : common petiole occasionally prickly, roundish, plane 

 above, pubescent ; partial, very short. Panicle terminal, in- 

 termixed with leaves, branched, of numerous very caducous 

 white flowers. Common peduncle angulose, striated, pubes- 

 cent, much and irregularly branched ; pedicels very short, fili- 

 form, several together. Calyx minute. Petals much larger, 

 spreading, ovate. Stamens 5, longer than the petals, with which 

 they alternate, spreading ; filaments subulate : anthers heart- 

 shaped. Ovary angular : stigmata 5, erect, appressed. Carpels 

 5, or by abortion fewer, distinct, puberulous, greenish. 



The bark of the root of this tree, dried and reduced to a 

 powder, is a common application to sores ; and an infusion of 

 it has the character of being antispasmodic. It is mentioned in
