glandular, scarcely scabrous, ten-nerved, five-cleft ; segments sub- 

 equal, lance-pointed sharply corneous acute, three-nerved ; the two 

 lateral nerves marginal, uniting into one at the bifurcations. 



Flowers bilabiate ; upper lip very short, emarginate, included ; 

 lower lip trifid, middle lobe elongated, expanded towards the apex, or 

 somewhat oblong obovate, sub-entire ; lateral lobes oblong divaricate, 

 intermediate declined ascending ; throat and lip villous within, glandu- 

 ular without, striate beneath. Below, at the base of the long stamens, 

 a pubescent ring nearly encircles a little pit or cavity with a dark 

 colored mons in front. Filaments bearded laterally at the base, 

 especially the lower longest pair. Stamens exsert, ascending from 

 the upper cleft, and recurved towards the lower lip. Anthers glan- 

 dular, reniform, confluent. Style equal ; stigma deeply bifid ; lobes 

 equal, subulate. Flowers blue. 



Achenia four, naked, oblong, sub-triangular, outer angle rounded, 

 inmost angle warted toAvards the slightly narrowed base ; apex obtuse, 

 hirsute, covered Avith glands. 



Rhus veatchiana, (Kellogg,] Elephant Sumac. — Leaves alter- 

 nate, oddly pinnate ; if from the older branch buds, in the condensed 

 fascicles of three to six ; leaflets opposite in about six pairs, small 

 [one-eighth to one-fourth of an inch in length] ; these lateral leaflets 

 sessile, ovate sub-acute, obsoletely serrate towards the apex [with 

 relatively large rounded teeth], terminal odd leaflet obovate, cuneate, 

 three or more cutlobed, or tridentate ; velvety, hoary villous, with 

 appressed hairs above, somewhat silvery hoary beneath [leaves about 

 an inch long, the common petiole occupying about one-fourth its 

 length.] 



Flowers very numerous, in closely clustered, oblong, fasciculoid 

 panicles occupying the terminal portion of the rigid branchlets ; ped- 

 icils filiform, attenuate below, enlarging upwards to the continuous 

 calyx ; very villous, minute subulate bracts at the base of the pedicels 

 [pedicels three-eighths to one-half an inch long]. Panicles bright red. 

 Calyx five parted, membranous, bright scarlet, hirsute with white 

 hairs, a few red glandular hairs intermixed ; segments ovate acute 

 [about one-third the length of the petals] ; petals five -imbricate, 

 membranous, paler red, a brighter line along the midrib, oblong-ovate 

 acute, somewhat carinate, apex slightly incurved [texture translucent 

 reticulate] hirsute mostly along the prominent midrib on the back. 



Stamens ten [seldom eight] inserted upon the scarlet cupped disk 

 under the ovary ; introrse anthers two-celled, opening together ; sta- 

 mens very short, white ; anther glabrous, fillets colored villous at base, 

 shorter than anther. Disk deeply five-lobed, the five stamens oppo- 

 site the lobes longest.
