PITTONIA 



flat-topped ; foliage nearly glabrous, orbicular or elliptical, 

 not at all corJate at base, crenulate-serrulate, about 1-^ inches 

 long, the sleiuler petioles about | inch, the 2 to 4 glands 

 either at summit of these or upon the base of the lamina : 

 fruit an inch long, or more, oyate, yellow when ripe, the 

 sarcocarp more pulpy and better flavored than in the type. 

 The typical P. subcordata is a smaller shrub, of stouter 



subcor 



on 



the branchlets (it is ash-gray in the variety), and smaller 

 almost oblong or roundish dark red fruit, the pulp of which 

 is harder and less palatable. 



The variety is abundant near Sierra City, Sierra Co., Calif., 

 where along with the type the writer has observed it almost 

 annually since 1SG7. It prevails generally in the more 

 northerly parts of the State, and has long been observed and 

 its superior qualities noted by my friend Mr. Sisson, of 

 Strawberry Valley at the base of Mt. Shasta, where it grows 

 plentifully along streams that course through rich meadow 

 lands.

 inflorescence paniculate-corymbose, the pedicels and bracte- 

 oles white-torn entose : bracts foliaceous, narrow ; bracteoles
