Part 3, 1923] FABACEAE: GALEGEAE 183 



Cracca VENOSA (Mart. & Gal.) Kuntze, Rev. Gen. 175. IS'M. Tephrosia venosa Mart. 

 & Gal Bull. Acad. Brux 1C": 47. 1843. Perhaps the same as C. Pringlei. but the pod is 

 described as glabrous. It came from Oaxaca. 



Tephrosia chrysophylla Mart. & Gal. Bull. Acad. Brux. 10 2 49. [843. Not /'. 

 chrysophylla Pursh, 1S14. This perhaps should be referred to Cracca Langlassei M. Micheli. 



Tephrosia (?) Elliottii Benth.; S. Wats. Bibl. Ind. 220, as synonym. 1S78. This 

 is based on Galactia Elliottii Nutt. and probably belongs to that genus. 



Tephrosia Barclayi Baillon, Bull. Soc. Linn. Paris 1: 388. 1883. This is a species of 

 Dalbergia. 



3 PETERIA A. Gray, PI. Wright. 1: 50. 1852. 



Perennial herbs, somewhat woody at the base. Leaves odd-pinnate, with stipular spines 

 and no stipels. Flowers racemose, the racemes terminal or by the development of an axillary 

 branch becoming opposite to the leaves. Calyx cylindric-catnpanulate, gibbous at the base 

 above, 5-lobed, the upper two lobes united high up. Corolla ochroleucous or nearly white. 

 Banner long-clawed, the blade obovate-oblong, with the sides reflexed. Wings with obliquely 

 oblong or obovate blades, slightly auricled at the base, and slender claws. Keel-petals slender- 

 clawed, the blades obliquely obovate, obtuse, with a broad rounded basal auricle. Stamens 

 diadelphous, the upper filament wholly free, straight; anthers uniform. Ovary short-stipitate 

 or sessile, many-ovuled, the style horny at the base, inflexed, glabrous, except at the apex, 

 where it has a ring of hairs under the stigma. Pod linear, straight, compressed, 2-valved, 

 without cross-partitions, with thick sutures, many-seeded.

 mm long; leaves 5-10 cm. long; rachis slender, glabrous, terete, in the upper leaves often 

 without leaflets; leaflets when present 9-15, elliptic, lanceolate, or nearly linear, acutish, 

 2-6 mm. long, more or less strigose beneath when young; racemes terminating the branches 

 or sometimes opposite the leaves; bracts subulate, 2-3 mm. long; pedicels 6-10 mm. long, 

 glabrous; calyx strigose, the tube 5 mm. long, the lobes deltoid, acuminate, 3 mm. long, the 

 upper two united to the middle; corolla 12-15 mm. long; blade of the banner obovate, retuse; 

 blades of the wings and keel-petals obliquely obovate, truncate at the base; pod pendulous,

2. Peteria glandulosa (A. Gray) Rydberg. 



Peteria scoparia glandulosa A. Gray; S. Wats. Proc. Am. Acad. 17: 342. 1882.

 9-13, oblong or elliptic, 4-6 or rarely 8 mm. long, acutish or inucronate, glabrous above, strigose
