FORESTIERA SPHJEROCARPA (n. sp.): foliis ad apicem ramulorum aggregatis, rhomboideo- 
oblongis parvulis acutiusculis superne crenato-serratis utrinque pubescentibus ; cymulis fcemineis 
trifloris ; pedicellis pubescentibus fructu subgloboso vix dimidio brevioribus. Dry ravines near

is easily distinguished by the small fasciculate leaves and small subglobose fruit. 
FORESTIERA ANGUSTIFOLIA (n. sp.): foliis fasciculatis lineari-spathulatis vel anguste-lanceolatis 
integerrimis obtusis glabris obsolete venosis subtus porulosis ; fructibus ovatis acutis. Western
