Leaflets 3. 
Short petioled, - - - R. TRILOBATA- 
With a very long petiole, - 8. RYDBERGII. 
rR. GLaBRA, L. (Smooth S.)Shrub 2 to 12 feet high; 
leaflets whitened be neath, lanceolate-oblong, pointed, 
serrate; fruit globular, clothed with acid crimson 
hairs; the stone smooth. In the canon above Camp 
Whitcomb. 
R. Trrtopata, Nutt. (Scented S.) 
A shrub 2 to 5 feet high, diffusely branched, 
strongly scented, leaflets cuneate-obovate, or rhomboi- 
dal, coarsely toothed above and often 3-lobed; flowers 
in clusters, scaly, bracted spikes like catkins, preced- 
ing the leaves, yellowish; fruit flattish, somewhat vis- 
eid. Common in the Hl Candelabria Society at the 
base of the mountains. 
R. Sarsirroria, Green. 
A sepecies so marked in the herbariam collected in 
June, ’08 ; seems t o be very similar to R. glabra except 
in the paler lower surface of the leaves. It is quite 
possible that my Rhus glabra belongs here. 
R. Rypserei, Small. 
Resembles somewhat the “poison ivy” of the East in 
leaf and raceme. The petioles of the leaves are some 
one foot long. Leaflets e ach coarsely toothed, ovate 
sometimes 3 inches long; nearly glabrous, very green 
above, paler beneath. Collected by C. L. Herrick in 
Sandia Mountains, June 1898. I have not found the 
plant growing. 
34. EUPHORBIACEAE, Spures Famity. 
Monoecious or dioceeious, mostly apetalous but some- 
times polypetalous flowers; ovary with a single ovule 
(sometimes 2) hanging from th summit of the cell and 
maturing in a mostly 3-celled elastically dehiscent pod. 
This difficult family has been imperfectly worked. It is 
certain that there are other species in’our range. The 
identification is difficult for a beginner. 
Flowers all without a calyx, collected in a cup-sheaped 
calyx-like involucre, . - - EUPHORBIA. 
Flowers with a calyx and no involucre. 
Whitened with a close stellate pubescent, CROTON. 
With long coarse stinging hairs, - - TRAGIA. 
Evpnorsis, L. Spurge. 
Herbs (ours), wit hmilky, bitter juice; what looks 
like the single flower to the novice is a head, which in-
