the blade ovate, the claw broad, channeled or folded, tapering 
gradually to the base, much longer than the blade; wings oblong, 
much shorter than the slender claw; the very narrow claws of the 
keel petals twice as long as their blades: pod thick-coriaceous, 
obcompressed, ovate, curved, the impressed dorsal suture nearly 
or quite meeting the ventral, white-hoary with a long soft dense 
tangled pubescence which is persistent. 
This has passed for A. glareosus Doug]. and is another case in eh species 
are difficult to distinguish by descriptions alone. These two may be at once 
separated, however, by the character of the pubescence. In A. glareosus it is 
silky with incumbent appressed hairs, while in A. Booneanus it is much denser, 
looser, and tangled. The pods also are distinguishing in that in the former they 
are glabrate at maturity; in the latter the shaggy pubescence is permanent. 
The species rests upon several very representative collections as follows: 
President W. J. Boone, of the College of Idaho, at Caldwell, no. 2, in whose 
honor the species is named; C. N. Woops, supervisor Sawtooth National Forest, 
Hailey, nos. 5 and 25a; MERRILL and Wrtcox, Leckie, Wyo., no. 583; an 
J. Francis Macsrinkg, Falk’s Store, Idaho, no. 57. 
LIGUSTICUM TENUIFOLIUM dissimilis, n. var—What is at 
least an interesting variety of this species was secured by Mac- 
BRIDE in his no. 677, from the Trinity Lake region, August 29, 
tg1o. At first glance one would not suspect any close relationship, 
but the technical characters show that size and aspect may be mis- 
leading. The following points may be enough to distinguish this 
variety: : 
Stem naked except for one or at most two reduced bractlike 
leaves near the inflorescence, 3-5 dm. high: leaves bright green, 
ternate then pinnate, 1-2 dm. long; petiole one-third to one- 
half the length; leaflets narrowly to broadly ovate, 15-25 mm. 
long, pinnately cleft into linear-lanceolate lobes 8-14 mm. long: 
rays 9-14, 25-40 mm. long; pedicels 8-12 mm. long: fruits essen- 
tially as in the species but larger, with longer and stouter stylo- 
podium. 
Cornus instoloneus, n. sp.—Cornus stolonifera of authors as to 
western and intermountain specimens; Swida stolonifera riparia 
Rydb. Bull. Torr. Bot. Club 31:573. 1904; Suida riparia in herb; 
not Cornus riparia Rafin.
