long, the general outline nearly oval, narrowly sulcate ventrally, most- 
ly translucent. Flowers normally white, inclined to be cleistogamous, 
about 5-7 mm. long, the petals mostly but little longer than calyx. 
Banner notched, oval 2-4 mm. long, with sides little: arched along 
the edges, about as long as keel or a trifle more. Wings oblong, 
nearly as long as banner, Keel very wide relatively, about 1.5 mm. 
wide below and at tip abruptly rounded to-erect and but a little higher 
' than the rest of keel and square. Calyx campanulate, the tube about 
. 2 mm. long, the teeth arched, triangular and fully as long as tube. 
Pedicels stout, 1-2 mm, long, shorter than the delicate bracts. Ped- 
uncles 1-3 cm. long, the floral rachis about as long. Leaves 5-7 em. 
long, ascending, on short petioles. Leaflets 5-8 pairs, folded, not con- 
tiguous, oblong, rounded at tip, about 1 cm. long. Stipules acuminate 
from a deltoid base.. Stems 1-2 ft. long, rather many from the crown 
and branched below, with internodes shorter than the leaves. Pubes- 
cence soft throughout, spreading, hoary. The flowers vary greatly in 
color and length of petais, The banner is often arched to erect, with 
light-pink claw and blade striate-purple-veined and with darker edges, 
the groove is a half circle and occupies most of banner or broadly 
triangular, in some specimens the banner has a purple streak below 
the notch and on the sides. The wings equal.the keel and ascending 
with tips just touching the keel tip, obliquely ovate and flat and obtuse. 
The keel tip is acute and narrow, pink but: not purple-tinned. The 
wings are often light-pink and often purple streaked, usually darker 
below. Other material has dark-purple flowers with very striate ban- 
ner. Some Colorado forms have the banner 2-3 mm, longer than keel 
and wings about intermediate. Frequent in the Lower Temperate life 
zone from Baker Lemhi Co. Idaho and the San Rafael Swell Utah to 
central Colorado and:southward at least to central Mexico. The type 
' locality is Mexico not Peru. Some forms are short-lived nerennias. 
Blooms in summer It grows in the hills and not on the plains in this _ 
country. DeCandolle’s fanciful figure is poor, that of H. B. K, is better. 
On the plains it is replaced by the following. Gray's type is mac e up 
Of A. lentiginosus var. diphysus partly. : 
The type of Phaca triflora DC. is a fanciful fieure drawn as though 
it were a weak annual, but corresponds in essential features with the 
species. Phaca Candolleana H. B. K. which was intended to he the . 
same thing is drawn without the root as though it were a perennial and 
bas narrower leaflets but otherwise the same. Jt also is a fanciful 
figure. Plants from the Valley of Mexico by Schaffner are clearly an- 
ual and early blooming and fit DeCandolle's figure. Plants of my 
own collection at Casnalidad Zacatecas and Ramos correspond well 
with both figures showine the species to be a winter annual or flower- 
ing in the spring and fall from the same plant, a thing very common 
in Mexico, and plants inseparable from the Colorado form called cerus- 
Satus by Sheldon. The type is too near to cerussatus for it to be 
kept up as a variety. Plants corresponding to cerussatus from Mexico 
also are those of Rose from Irola No. 4558. At Baker Idaho I found it 
growing and in fruit in September and evidently in condition to live 
over the coming winter and thus at least a biennial. Parish sends me 
à form from Leastalk San Bernardino Co. California clearly peren- 
nial with mottled smooth pods and short calyx teeth. Plants growing 
in the San Rafael Swell Utah have the dense hobit of cerussatus and 
fine and soft pubescence and beautifully mottled nearly globose pods, 
elongated calyx teeth and dark-pvrrie flowers, apnearing so like A. 
pubentissimus that only an examination of the pods and calyx teeth 
can separate them. These plants also bloom as annuals and winter 
annuals but the two species d^ not seem to hybridize. A. Coquim- 
bensis answers fairly well to this species. The species is very 
variable in the pods and pubescence. |
