A NEW VARIETY OF ILEX VOMITORIA 
FROM SOUTHERN MEXICO’ 
BY 
A. J. SHARP 
Ilex vomitoria [ Soland. in] Aiton var. chiapensis 
A. J. Sharp var. nov. 
Haec variatas ab Ice vomitoria principaliter foliis pu- 
bescentibus et ramulorum villis longioribus differt. 
From the species, this new variety differs primarily in 
having loosely pubescent leaves and longer (about twice 
as long) hairs on the branchlets. There is a tendency for 
the leaves to be a little more ovate and obtuse at the 
apices, although many leaves match in shape those from 
North American material of the species. The material 
of Ilex vomitoria in the Gray Herbarium (all from south- 
eastern United States) has been examined, and the leaves 
are glabrous, except for occasional puberulence on the 
mid-rib at the base. 
This report adds another species to the growing list 
of plants which occur both in central or southern Mexico 
and in southeastern United States. In Mexico, their 
ranges are disjunct from their areas in the United States, 
and the largest number of such species seems to be found 
in the highlands toward the Gulf of Mexico. <A fuller 
discussion of the phytogeographical problem basic to 
this interrupted distribution will be presented later.
