 der, gray or purplish-gray. Leaves 4 to 9 cm. long, 1 to 2.5 cm. 

 wide, lance-oblong, abruptly contracted into a short, obtuse acu- 

 niination at the summit, very abruptly contracted into a petiole- 

 like base 2 or 3 mm. long, with incurved or involute margins; 

 upper portion of the margin obsoletely serrate ; coriaceous, deep- 

 green, slightly shining above, the venation scarcely prominent 

 on either side, the strongly ascending secondaries 12 to 15 pairs, 

 often with a few smaller ones alternating at the basal portion. 

 Fruits solitary or 2 or 3 together in the axils, the pedicels 2 or 3 

 mm. long, stout, purplish, the persistent thickish calj^x 2 mm.

San Rafael, near Reyes, 1,000 feet, M. Cardenas, October 29, 

 1921 {no. 1379). Species near M. eriithrocarpa. 



Maytenus erythrocarpa 



(Fruiting specimen.) Glabrous, the branchlets gray, slen- 

 der, somewhat flexuous, subterete. Leaves alternate, the reddish 

 petioles a])out 6 mm. long, broad. Blades 6 to 10 cm. long, 3 to 5

 opened fruit broadly oval or subglobose, about 1 cm. long, 

 brownish-red, dehiscing nearly to the base, the thick valves 

 spreading widely and displaying a two-lobed aril of the same
