﻿310 Wootox : New Plaxts from New Mexico 



rarely seen, only a few berries on the many-flowered cymes ma- 

 turing, and the trunk is always rough and gnarled. It is always 

 to be found in the valleys below irrigation level, while our plant 

 grows only in the mountains, so far as I have observed. 



5. Neo-Mcxicana seems much nearer to 5. glanca, but its 

 leaves are little over half as wide as those of that species and 

 there is a noticeable tendency to puberulence upon peduncles and 



leaves. 



SlCYOS GLABER. 



Annual ? stems slender, 4-6 m. long, climbing over bushes, 

 striate, glabrous except near the nodes and towards the growing 

 ends, where they are viscid villous ; tendrils 3-4-branched from a 

 stout base 3-5 cm. long: leaves thin, 5-12 cm. long and almost 

 as broad, 5-lobed, lobes triangular-ovate, the terminal' one larger 

 and short acuminate, mucronate, margin coarsely sinuate-dentate 

 with mucronate teeth, deeply cordate, the sinus 2-2.5 cm. deep 

 and 3-4 cm. wide not overlapping, upper surface scabrous wi ' 

 tuberculate white hairs, lower surface more sparingly hairy wi 

 weaker hairs; petioles 0.5-5 cm. long, viscid with a pubescence 

 which follows up the main veins especially on the upper surface of 

 the leaf: staminate flowers in strict racemes, 1 5-20-flowered, 1-2 

 dm. long; peduncles viscid, pedicels 3-4 [mm. long, glabrous,

Collected in the Organ Mountains south of San Augustine 

 Ranch, September 1. Alt. 5000 feet, no. 606. First collected 

 on the other side of the same mountain range September 17, 1893- 



This plant belongs in the subgenus Eusicyos and, judging from 

 the description, is most nearly related to S. Galcottii Cogn. Monog. 

 Phan. 3: 883.
