1U4 Inflati 



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 nuicronate, 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 Hornlj var. Bajaensis (Sheldon Minn. Bot. Stud. 9 169 

 (1894) as species) var. minutiflorus Jones. A. miserandnis 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- 

 nia 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 shai)e by pressing. 



47. Astragalus insularis Kell. Bull. Cal. Acad. 1 6 (1884). A tri- 

 tlorus var. insularis (Kell.) Jones. Pods decidedly obliq le, not s.ilcate, 

 sm-^oth, about 1 cm. long and nearly as wide and high, obliquely ovate, 

 rntber narrowed below and with a flfit 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 

 I mm. 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. 

 lorg. 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. Tro! icpl . 



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 i)eduncles, nearly glo- 

 bose pods with the flat tip reduced to a mere ajiiculation 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 I>ower 

 California. This has been referred to A. triflorus, but that is a bien- 

 nial or winter annual and does not seem to grow on the Pacific 

 Coast. 



48. Astraglus triflorus (DC.) Gray PI. Wr. 2 45 (1853). Phaca 

 triflora DC. Ast. 50 t 1 (1802). Phaca Coquimbensis H. & A. Phaca 

 Candolleana H. B. K., A. cerussatus Sheldon, A. triflorus var. Can- 

 dolleanus (H. B. K.) Jones. Pods 1-2.5 cm long, 7-10 mm. wide, 

 almost oval, abruptly acute at both ends to barely acute at base, veiny 

 only when old and then shortly-pubescent only, only a little oblique, 

 the tip a mere apiculation sometimes flattish and little over 1 mm.
