380 Notes from the Gray Herbarium. [zoe 



six inches long, 8-10 flowered: upper sepal ovate-orbicular, cucul- 

 late, about three lines in length; the lateral ones ovate-elliptic, 

 obtusish, four lines long: petals deeply two-parted, upper seg- 

 ment linear, falcate, obtuse, dilated at the base, ascending, 

 nearly equalling the sepals,* lower segment filiform, about an 

 inch in length; labellum three-parted to the base; the outer seg- 

 ments about fifteen lines long; the middle one linear, obtuse, a 

 third to a half as long; spur clavate, free, 14-17 lines in length: 

 ovary angled and obsoletely winged, about equaling the bracts; 

 the two appendages of the stigma deeply bifid; the segments 



linear, spreading laterally, and curved ascending, retuse. 



Collected on mountains of the Cape Region of I^ower California, 

 by T. S. Brandegee, September 16, 1893. 



A stout species resembling in habit H. Michauxii Nutt., 

 of the Southern States, but differing in its broader leaves, longer 

 segments of petal and lip, and shorter more clavate spur. 



Ali<ium acuminatum Hook. var. cuspidatum n. var. Scape 

 more slender than in the type: perianth segments oblong, abruptly 

 cuspidate, about the length of the stamens: bulb-coats more finely 

 and less distinctly reticulated. Collected at Wawawai, Wash- 

 ington, June, 1892, by Mr. W. R. Hull (No. 619). 



Professor Porter's No. 74, from Weber River Valley, Utah, 

 seems to be a form near this, but with the perianth segments 

 tapering more gradually to the point, and with the stamens 

 mostly short as in the type. 



Trifolium gracilentum Torr. & Gray, var. inconspic- 

 UUM, n. var. Much smaller than the type, slender, 2-6 inches 

 high: leaflets 3-4 lines long, on petioles 3^-1^ inches long: 

 heads 3 lines high; corolla shorter than or barely equaling the 

 calyx. •, Roadside, San Bernardino, Cal., Parish No. 2647. 



Forms of the type approach this in habit, but the corolla is 

 conspicuously longer than the calyx, as Orcutt's No. 1004 from 

 Tia Juana, Lower California, and Palmer's No. 583 from Wick- 

 enberg, Arizona.
