52 JOURNAL OF THE ARNOLD ARBORETUM [vol. v 



Texas: Sandy Tine lands, Silsbee, Hardin County, E. J. Palmer, no. 

 9561, April 25, 1916 (type) ; Angelina County, J. Reverchon, no. 3863, May 

 5, 1903 (distributed as Vaccinium corymbosum) . 



This form is easily distinguished from the type by the soft pubescence 

 of all its parts except the corolla ; the leaves of the type specimen are gen- 

 erally elliptic-oblong and from 4 to 6.5 cm. long and 1.3 to 3 cm. wide. 

 The branchlets, calyx and leaves of the typical form are glabrous or some- 

 times the midrib and veins on the under side of the leaves are slightly 

 or rarely rather densely villous and the calyx is sometimes sparingly hairy, 

 but none of the numerous specimens seen from the whole range of the 

 species approach this new form in its densely villose pubescence. I have 

 seen no other material of X. mariana from Texas and I find no record of 

 its range extending as far west; the most western specimens seen are from 

 Jefferson and Pulaski Counties in southeastern and central Arkansas (E. 

 J. Palmer, nos. 8481 and 22999).

Pieris pilosa Komatsu in Matsumura, Icon. PI. Koisikav. in. 73, t. 182 (1916). 

 This species differs from the preceding in its lateral and occasionally 

 terminal elongated racemes usually with a few leafy bracts near the base. 

 In its typical form it inhabits the Himalayas from Kashmir to Bhutan 

 and extends to Assam, Khasia and British Burma and to southwestern 

 China, and Formosa.

Pieris formosana Komatsu in Matsumura, Icon. PI. Koisikav. m. 71, t. 181

This variety differs chiefly in the narrower leaves, usually broadly 



cuneate at base or sometimes rounded and in the longer and narrower 



greenish sepals. It seems to have about the same range as the type.
