FLORA OF THE CAPE REGION. 121 



mountains. About Buena Vista the bark has been cut 

 from the trunks and larger limbs of the trees and exported 

 for tanning purposes. The trees do not die, for the cut- 

 ting is not deep enough and the bark is not completely 

 removed. 



93. BuRSERA HiNDSiANA (Benth.) — San Jose del 

 Cabo. Forms with simple leaves only. 



94. BuRSERA LAxiFLORA Watson. This seems to be 

 one of the most variable species in regard to its foliage 

 and but for the forms from San Jose del Cabo that ap- 

 proach so closely B . laxifora collected at Guaymas by 

 Dr. Palmer, it would be considered a distinct species. 

 The bushes near La Paz growing upon the low sand 

 beach opposite the town bear simply pinnate, densely 

 white-pubescent small leaves; trees from the interior and 

 Todos Santos have large, sometimes ver}^ pubescent 

 leaves, with the larger ones more or less doubly pinnate. 

 The Cape specimens have longer and narrower leaves, 

 with the leaflets more distant and appear to be the same 

 as Dr. Palmer's Guaymas specimens; they are not as 

 handsome as the more northern forms with pubescent 

 fern-like leaves. An acquaintance with this tree through- 

 out a large extent of country convinces me that the forms 

 belong to one species. It is found as far northward as 

 the low region opposite Santa Margarita Island. 



95. BuRSERA CERAsiFOLiA. A bush or Small tree, 4-5 

 m. high, branched from the base, glabrous; leaves simple, 

 sessile, crowded at the ends of the branchlets, ovate- 

 lanceolate, 4-6 cm. long, 1-2 cm. wide, slightly crenate, 

 thin in texture, with numerous veins nearly at right an- 

 gles with the midrib ; peduncles apparently terminal but 

 really from the axils of the leaves, slender and exceeding 

 them, 1-3 flowered; sepals 4, unequal, subulate or del-
