THB GBNUS SAVINIONA. 161 



parted nearly to the base into 3 subtrigonous obtuse segments, 

 this and the calyx sparsely and minutely stellate-pubescent ; 

 mature calyx cleft to about the middle, the somewhat enlarged 

 segments broadly triangular, reticulate- veiny and hirtellous : 

 pedicels under the flower spreading horizontally, under the 

 fruit firmly upright, straight at all stages, jointed Vo, inch 

 below the fruit. 



Known only from a single tree on San Clemente Island, 

 California, whence specimens were taken in June, 1903, by 

 Blanche Trask. This and the next, from an adjacent island, 

 differ from all other species in that the peduncles are firm and 

 straight. The color of the corolla in this one is peculiar 

 among the species of Saviniona. 



S. RETICULATA. Shrub 4 high, with stem 4 inches thick : 

 maple-like foliage 3 inches long, 3/^ in breadth in the middle, 

 the base with broad open sinus, the lobes with coarse obtuse 

 teeth ; petiole not longer than the blades and stout : corolla 

 of usual size, clear white, the petals neither obcordate nor 

 emarginate, only retuse : pedicels short and straight, only 

 1 inch long, jointed yi inch below the flower ; involucre with 

 oval obtuse segments ; fruiting calyx an inch high, its seg- 

 ments ovate, hardly acute, strongly favose-reticulate and 

 rough with a not very dense stellate pubescence. 



Type specimens collected on Santa Catalina Island, Cali- 

 fornia, in both flower and fruit in Febr., 1898, by Blanche 

 Trask, erroneously distributed for 6'. as surgenti flora, to which 

 it is not intimately related, being of the blue-purple-flowered 

 group. Apparently only a solitary plant was known to 

 Mrs. Trask. 



8. DENDROiDEA. In form a perfect tree, only 10 or 12 feet 

 high, but with distinct thick trunk and no branches below 

 the middle : leaves very ample, the largest 9 inches long, of 

 the same width, but on old flowering branches of less than 

 half that size, not deeply lobed, the cleft seldom reaching to 

 the middle of the blade, the 3 terminal lobes far exceeding
