T. ISOPHTLL0M. Stoutish upright striate stems velvety- 

 puberulent not only the first but also the second and third seasons: 

 leaves palmately trifoliolate, the leaflets being equal in size and 

 all three sessile, 1 to 1} inches long, of somewhat obovate gene- 

 ral contour but pinnately sinuate-lobed, the rounded lobes not 

 deep, but in about 3 always opposite pairs, dark green above, yet 

 dull and with a glaucous hue, paler beneath, with very few and 

 scattered appressed hair points on both faces, but between the 

 veins, not along them : fruits small, the epicarp not polished 

 but dull and muriculate- punctate as well as somewhat pubes- 

 cent, the roundish but notably compressed putamen ribbed and 

 striated. 



Eiver banks near San Jacinto in southern California, 9 March, 

 1898, J. B. Leiberg, n. 3117 as in U. S. Herb. Most distinct 

 from all others by the sessile terminal leaflet ; the lobing also 

 not imitated by any other forms in the I", diversilobum aggre- 

 gate. 



T. OXYCAEPUM. Twigs smooth, free from angles and lenti- 

 cels, slightly puberulent : leaves thin, very large, the terminal 

 leaflet 3 to 4i inches long, oval, coarsely and evenly crenate- 

 lobed, the laterals smaller, inquilateral, entire on the narrower 

 side, on the other lobed like the terminal, deep green and glab- 

 rous above, beneath paler, with a few hirtellous hairs along the 

 veins and on the margin : inflorescence paniculate but the bran- 

 ches of it only two or three and very short : fruit on slender 

 pedicels and pendulous, notably compressed and of singularly 

 oblique-rhomboid outline, tapering turbinately from above the 

 middle to the base, the upper part more abruptly acute, epi- 

 carp not striate, but irregularly sharply and deeply wrinkled, 

 minutely hirtellous-puberulent. 



Vicinity of Santa Cruz, Calif., July, 1884, John Ball; type 

 in U. S. Herb. Also from the Salinas Valley, back of Monterey, 

 Aug., 1880, Gr. E. Vasey. I suspect the shrub of having the 

 climbing habit. Its habitat is in the redwood forest. 



T. DETOPHiLUM. Dendrophilous, climbing trees to the 

 height of ao feet : branches puberulent, knotted by salient pro- 

 tuberances under the insertion of the leaves : foliage large, 6 to
