New species of western plants 



Alice Eastwood 



•^ Clematis biflora sp. nov. 



Lower leaves pinnately compound, with 5 ternate or quinate 

 leaflets ; petioles and rachis tomentose especially at the axils, 

 horizontally spreading; leaflets ovate-acuminate, the terminal 

 about twice as long as the lateral, 4 cm,, dentately lobed, the 

 teeth or lobes mucronate, base obtuse, surface somewhat pubes- 

 cent but not tomentose, veiny, bright-green ; leaves of the flower- 

 ing sterns simpler, much smaller, the leaflets cuneate at base : 

 peduncles axillary, 2-flowered (sometimes i -flowered from the 

 abortion of the other bud); bracts minute, simple or trifoliate: 

 flowers perfect, with sepals elliptical to oblanceolate, rather thin, 

 15 mm. long, about half as wide, obtuse or mucronate, tomentose : 

 stamens shorter than the sepals, with flat filaments in 2 or 3 sets ; 

 anthers narrowly oblong, 1.5 mm. long, as broad as the filaments : 

 carpels bristly-ciliate with discontinuous cilia, hispid at the top 

 and with densely plumose tails an inch or more in length. 



This species was collected by Mr. T. S. Brandegee on the 

 Island of Santa Cruz, off the coast of Santa Barbara, California, 

 April, 1888, and listed as C. pattcifiora Nutt, in the list of the 

 plants of the island published in Zoe (l : 131). From this species 

 it differs in the acuminate, more numerous, and larger leaflets ; 

 flowers equal in size to those of C. lasiantha Nutt.; sparingly his- 

 pid akenes and densely plumose tails. It is also allied to C, 

 lasiantha^ but differs in the absence of tomentose pubescence, the 

 more numerous leaflets, the thinner and less tomentose sepals and 

 the more glabrous carpels, and most especially in the two-flowered 

 peduncles. 



/Aquilegia Shockleyi sp. nov. 



Stems branching, glabrous on the lower part, viscid-pubescent 

 on the upper, clothed at base with the bleached persistent remains 

 of the leaves, about 4 dm. high : radical leaves varying in length
