the leaves on pedicels 2 to 3 Hues loug: calyx 2 to 3 lines long, deeply 

 five-lobed into ovate lanceolate divisions : corolla, lilac, 10 lines long, 

 longer than the leaves, the lower lobes 5 lines broadly oval: seeds 

 scarcely roughened, glabrous. 



This species is very distinct from any T^orth American representative 

 of this genus. It resembles T. laciniata in its general habit, but its 

 leaves are very different, all its floral leaves being entire and the lower 

 ones merely dentate; the seed is also similar but smaller. T. glandii- 

 losuni of Cedros Island has the floral leaves entire, but it is a taller 

 form with a loose inflorescence, long pedicels and different seeds. We 

 take pleasure in dedicating this species to the collector, Mr. Charles H. 

 Townsend.

SAPINDACE-53.

Climbing over bushes; stems cauescent-tomentose : leaves tomentose 

 on both sides, biternate on petioles, half inch long ; leaflets from 1 to 

 4 inches long, sessile or on petiolule 3 to 4 lines long, ovate or oblong, 

 coarsely dentate : peduncles 3 inches long : flowers rather large : the 

 two outer sepals a half line long, broadly ovate, a little hirsute; the 

 two inner, 2 lines long, oblong, glabrous ; the two hypogynous glands 

 short and rounded : petals white : capsule membranous, 12 to 18 lines 

 in diameter, minutely hirsute to almost glabrous. C. H. Townsend, 

 Socorro Island, March, 1889 ; Dr. Edward Palmer, La Paz, Lower Cal- 

 ifornia (No. 68), January 20, 1890. 



Mr. Townsend got only a few capsules and a single leaf. Dr. Palmer's 

 collection contains both flowers and fruit, and enables us to charac- 

 terize this as a good species; this specimen has somewhat narrower
