WESTERN PLANT STUDIES. V 
AVEN NELSON AND J. FRANCIS MACBRIDE 
SISYRINCHIUM IDAHOENSE Bickn., var. birameum (Piper), n. 
comb.—S. birameum Piper Contrib. Nat. Herb. 11:203. 1906.— 
This variety may be distinguished ordinarily by the presence on the 
plant of one or more branched stems. Professor J. K. Henry of 
Vancouver has kindly sent us specimens of the species transitional 
to the variety. ‘These are deposited in the Gray Herbarium under 
his no. 9056 and were secured June 27, 1916, near Alberni, Van- 
couver Island. He wrote regarding them “all growing together 
and sometimes in the same bunch.” 
Sisyrinchium boreale (Bickn.), n. comb.—Hydastylus borealis 
Bickn. Bull. Torr. Bot. Club 27:378. 1900.—BICKNELL was surely 
justified in segregating this small-flowered inhabitant of inland 
lakes from the truly maritime large-flowered S. californicum. 
H. brachypus Bickn., loc. cit. 379, however, seems to be only a state 
of S. californicum that is unworthy any formal recognition. 
Brodiaea coronaria (Salisb.), n. comb.—Hookera coronaria 
Salisb. Parad. Lond. #/. 2. 98. 1801; B. grandiflora Smith, Trans. 
Linn. Soc. 10: pl. 1. 1811.—SMITH cites SALISBURY’S name as a 
synonym, and comparison of the plates shows that both authors 
had in mind the same plant. 
Allium scissum, n. n.—A. incisum Nels. and Macbr. Bort. GAz. 
56:470. 1913; not A. incisum Fomine in Monit. Jard. Bot. Tiflis 
14:52. 1909. | 
Trifolium Leibergii, n. sp.—Stems flexuous, 8-15 cm. high, 1- 
several from the summit of a woody taproot: petioles, leaves, and 
peduncles canescent with a dense covering of fine crinkly hairs: 
petioles 1-2.5 cm. long; leaflets obovate or subrotund, 1-1.5 cm. 
long, about 1 cm. broad, spinulose-serrate above the entire cuneate 
base: peduncles 1.5—2 cm. long; heads 1.5-2 cm. in diameter; 
flowers reflexed in age, distinctly pedicellate: calyx pubescent like 
the rest of the plant but the hairs longer and tangled; lobes linear- 
lanceolate, setaceous-acuminate at tip, nearly equal, thrice the
