Oenothera gauraeflora var. vcrmiculata n. var. 

 Prostrate, nearly glabrous, with several branches bearing 

 dense tufts of leafy-bracted spikes at the ends; leaves linear- 

 oblanceolate, 2-3 lines wide, 1-2 inches long; petioles half the 

 whole and verv slender ; flowers about 1-2 Unes long, pods near- 

 ly glabrous, much coiled and twisted, 6-9 lines long, with 4 very 

 broad and thick angles leaving a deep crense between. This 

 is verv marked but intergrades with the species. Reno, Ne- 

 vada, June 10, 1897, and May 27, 1903. 



Petalonyx Thurberi var. nitidus (P. nitidus Watson Am. 

 Nat. 7. 300). This intergrades with the type. 

 Mcntzelia albicaulis var. spectabilis, n, var. 

 Petals 4-6 lines long, bright yellow ; lower leaves linear and 

 deeply pinnate lobed, upper triangular and mostly entire ; inter- 

 nodes long and shining. A very conspicuous form and very 

 common from Arizona to Death Valley and Owen's Valley, 

 Cahfornia. 



Mcntzelia Dieh'ii n. sp. 



Stems several from an erect tuber which is about 3 inches 

 long and 1 inch thick;, habit of M. hispida; leaves ovate, 

 petioled. lyi inches long, doubly toothed; flowers terminal; 

 petals 6 lines long, orange ; calyx lobes linear, 3-4 lines long ; 

 immature pods 6 lines long, 2 lines wide, on a pedicel 2-3 Hnes 

 long ; whole plant ashy-hispid and very adhesive ; stems stout, 

 2 foot long, erect, nearly simple. This accords fairly well with 

 M. scabra HBK. Nov. Gen. & Sp. 3 405, but that is said to dif- 

 fer from M. hispida only in the stamens, while this is much 

 different from it. It also grows onlv in the Andes. Colonia 

 Juarez. Chihuahua, Mex.. 6000 feet alt., in the Lower Temper-

Cymopterus (Aulospennum) basalticus n. sp. 

 Acaulescent or with stems not rising above the ground or 

 much exceeding the old leaf-sheaths, from a fleshy rather 

 elongated and little branched thick root; crowns one to sev- 

 eral, densely clothed with the fibrous 1-2-inch-long old leaf 

 sheaths, underneath which and rising above them ?re 3-5 new, 

 ribbed, hyaline leaf bases imbricated and about 6 lines wide 

 embracing and mostly concealing the very short stems from
