upon the tree, valves tardily separating from about the 

 seeds, which are oval, smooth, flattened, 6-10 mm. long, 

 transversely attached by long, slender f unicles : radicle very 

 short, covered by the downward prolongation of the cotyle- 

 dons. It app<!ars to be very distinct from L. microphylla of 

 Los Angeles Bay and Cape San Lucas, and is well known 

 in the region about Purisima and Comondu by the name 

 " palo bianco." The bark is excellent for tanning hides, 

 and most of the wine of the country being made in these 

 hides, receives a somewhat disagreeable flavor from the 

 *'palo bianco" and " torote."

RiBES TORTUOSUM Benth. ? Probably tliis species, but as 

 the description was drawn from the plant in flower before 

 the leaves appeared, the determination is uncertain. In all 

 the comparisons that can be made between fruiting plants in 

 full leaf and flowering leafless ones, they agree. The lobes 

 of the calyx (attached to the mature fruit) are quite variable 

 in length compared with the tube, sometimes agreeing per- 

 fectly with the description but often of equal length. The 

 leaves of the same length as the pubescent pedicles are 

 somewhat reniform, nearly glabrous, 5 - lobed, doubly 

 crenate, the largest more than 2 inches in breadth and
