Tkixis angustifolia, DC, var. latiuscula, Gray. A very 

 compact shrub, 2 or 3 feet high, common upon the summit of S. 

 Pedro Martin Island. (408.) 



Lobelia splexdens, Willd. Near a waterfall in the mountains 

 above Guaymas. (301.) 



Jacquinia pungexs, Gray. "San Juanico " ; a small evergreen 

 tree, 12 to 15 feet high, the wood useless even for fuel. The globose 

 fruit is 8 or 9 lines in diameter, the seeds several, oblong-peltate, im- 

 bedded or enclosed in the resinous-waxy placenta. The flowers are 

 used by the Indians to give a durable yellow color to the palm-leaves 

 used in making baskets, etc., and they are also strung like beads and 

 worn for ornament. About Guaymas. (G9.) 



SiDEROXYLON LEUCOPHYLLUM. A Small tree, 5 to 8 feet high 

 and sometimes a foot in diameter : leaves finely white-tomentose on 

 both sides, oblong-elliptic or -lanceolate, obtuse or acutish, subcuneate 

 at base, short-petiolate, 2 inches long or less : flowers rather crowded 

 in the axils on short pedicels, 5-merous ; calyx tomentose, campauu- 

 late ; corolla greenish yellow, 2i lines long : staminodia petaloid, en- 

 tire, broadly lanceolate, equalling the corolla : ovary densely villous. 

 — The fruit was not collected. The wood is hard, burning with 

 much smoke. In deep cafions near Los Angeles Bay. (51G.) 



Vallesia dichotoma, Ruiz & Pavon. A large evergi-een bush 

 with white fruit, which is eaten by children, and its juice is used for 

 inflammation of the eyes. This specific name is adopted as the oldest 

 in the genus, in preference to the later V. glabra of Link. The spe- 

 cies so named that is found in Florida and the West Indies appears to 

 have longer pedicels, a larger calyx, a longer corolla with longer nar- 

 rowly oblong lobes, and the leaves oblong rather than lanceolate. — In 

 garden hedges and sandy ravines about Guaymas and Muleje. (32.)
