Bumelia eloxochitlensis appears to be very closely re- 
lated to B. persimilis Hemsley of Vera Cruz, a rare plant 
which, so far as I have been able to ascertain, has not 
been found again since the type collection was made. I 
have examined an isotype of Bumela persimilis which is 
in the United States National Herbarium and find that 
it differs from B.elowochitlensis chiefly in having apically 
obtuse or very rarely subacute, instead of long acumi- 
nate, leaves. The leaves of Bumelia elowochitlensis are 
larger and the flowers appear to be grouped in looser 
fascicles. here are also minor differences in the flowers 
which serve to distinguish between the two; the most im- 
portant floral differences are in the size and shape of the 
anthers and petals. 
In its habit, Bumelia elowochitlensis is very similar to 
Dipholis salicifolia (.) A. DC., but it is armed with 
small woody spines whereas D. salicifolia is unarmed. 
The small fruits of Bumelia elowochitlensis are borne 
in great abundance and are said by the Mazatecs of San 
Antonio Eloxochitlan to be eaten. They are reported to 
be sweet and mucilaginous and to possess diuretic prop- 
erties if eaten in quantity. The tree is known by the 
Spanish names: tempiste and zapotillo bravo; and by the 
Mazatec name: ya-ntsin-tsu.
