fruit often 2 dm. long, spreading at about 30 degrees. Leaves 7-12 cm. 
long, widely spreading. Leaflets nearly contiguous, elliptical-linear to 
oblong-ovate, long petiolulate, not mucronate, nearly smooth, not over 
2 cm. long, obtuse, 10-15 pairs. Pubescence scanty. Stipules very 
small, subulate, soon reflexed, All but the lowest internodes shorter 
than the leaves. Much branched slender annuals growing decumbent 
on alkaline flats in the San Joaquin valley and southward, common. 
Astragalus Hornij var. Bajaensis (Sheldon Minn. Bot. Stud. 9 169 
(1894) as species) var, minutiflorus Jones. A. miserandrus Greene. 
Pods 1 cm, wide, somewhat obcompressed so that in drying and press- 
ing in herbarium material they are flat with the sutures in the middle, 
nearly oval, with a short and conical beak, a trifle sulcate ventrally, 
nearly smooth, veined. Flowers about 5 mm. long, stubby and petals 
all about equal. Calyx tube 2 mm. long, with blunt teeth much shorter 
than the tube, Peduncles slender, 3-5 cm. long, shorter than the leaves. 
Most of the leaves petioled, 1 dm. or less long. Leaflets thin, 6-11 pairs, 
oblong-obovate, not over 1 cm. long. Stems low and slender. This is 
a much reduced and delicate form from the borders of southern Califor- 
via and southward in Lower California. Sheldon’s description would 
lead one to think that the pods were 2-celled and closely allied to A. 
lentiginosus, but the specimens on which his species is founded are 
wholly 1-celled and sutures approach each other only in the crushing of 
the normal shape by pressing. 
47. Astragalus insularis Kell. Bull. Cal. Acad. 1 6 (1884). A tri- 
florus var. insularis (Kell.) Jones. Pods decidedly oblique, not sulcate, 
smooth, about 1 cm, long and nearly as wide and high, obliquely ovate, 
rather narrowed below and with à flat deltoid beak about 3 mm. long. 
Flowers with blade purple-tipped, about 5 mm. long. Banner about 3 
mm. long, oval, arched to 45 to 90 degrees beyond teeth, purple striped 
below as are the wings. with sides somewhat reflexed below, about 
1mm. longer than keel. Wings oblong, about as long as keel or a trifle 
more. Keel large, with straight base and then abruptly erect into a 
triangular and acute tip about 3 mm. high. Calyx tube almost hemis- 
pherical, about 1 mm, long, about as long as the triangular teeth, al- 
most sessile. Bracts hyaline and minute, Peduncles 1-2 cm. long, fili- 
form, the rachis somewhat longer. Leaves widely spreading, 5-10 cm. 
long. the petiole as long as the leaf rachis. Leaflets 3-6 pairs, linear- 
elliptical, apiculate, in the type about 1 cm. long, distant. Stems 
in the type much branched at base and running out very long, flex- 
uous, very slender and tangled, annual. Cedros Island Lower Cali- 
fornia, Trorical. 
Astragalus insularis var Pondii (Greene Pitt. 1 288 (1889). as 
species.) This is a larger plant with rather strict stems and strict 
peduncles, not tangled, leaflets often 10 pairs and pods nearly oval. 
Bay of San Bartolemo Lower California, Lieut, Pond. 
Astragalus insularis var. Quentinus Jones Cont. 8 6 (1898). This 
is a very open and slender form with short peduncles, nearly glo- 
bose pods with the flat tip reduced to a mere apiculation and pods 
about 2-2.5 cm. long and tissue-like, the leaves often 1.5 dm. long 
and with leaflets many and fully 2 cm. long. San Quentin Bay Lower 
California. This has been referred to A. triflorus, but that is a bien- 
ee or winter annual and does not seem to grow on the Pacific 
oast. 
. Only when old and then shortly-pubescent only, only a little oblique, 
3 tion sometimes flattish and little over 1 mm. _
