those of the upper lip slightly longer than those of the lower lip: corolla crimson; 

 standard 11-13 mm. long, linear-spatulate. Differs from T. arvense in the deeply 

 colored corolla which exceeds the calyx.

Page 608, after Lotus Helleri, insert : 



lOa. BONAVERIA Scop. 



Herbs with diffuse branches and nearly glabrous foliage. Leaves alternate: 

 blades pinnately several-f oliolate : leaflets with entire blades. Flowers perfect, in 

 peduncled heads. Calyx short, the lobes about as long as the tube, the 2 upper ones 

 decidedly united. Corolla yellow: standard broad, shorter than the other petals, 

 clawed: wings longer than the incurved keel. Stamens 10, diadelphous (9 and 1). 

 Anthers all alike. Ovary sessile. Style incurved. Ovules several. Pod elongated, 

 falcate, flat, slender-beaked. Seeds several. Differs from Lotus in the decidedly 

 2-lipped calyx and the indehiscent long-beaked pod. 



1. Bonaveria Securidaca Scop. Plants mostly 1 m. tall or less : leaflets 1-2.5 

 cm. long; blades cuneate to oblong-cuneate, rounded, or truncate and apiculate at the 

 apex: peduncles pubescent near the base: calyx 2.5-3 mm. long; lobes of the lower 

 lip lanceolate-acuminate: standard oval, 68.5 mm. long: wings 7.5-9.5 mm. long: 

 pods 6-9 cm. long, the slender beak hooked at the apex. 



In waste grounds, Charleston, South Carolina. Naturalized from the Mediterranean 

 region. Spring and summer. 



Page 610, after Cracca purpurea, insert: 



5a. Cracca corallicola Small. Boot very tough. Foliage densely pale-hairy 

 all over, the branches, peduncles and petioles short-hirsute: stems erect, 4-19 dm. tall, 

 densely branched, the branches decidedly zigzag, rather rigid: leaves numerous, 4-11 

 cm. long; stipules quite persistent, 1-3 mm. long; leaflets 11-15, 9-31 mm. long, the 

 blades linear to linear-oblong, mucronate, prominently ribbed, copiously pubescent: 

 racemes several-flowered, borne on short peduncles: pedicels stout, becoming 2-3.5 

 mm. long: calyx permanently hirsute; lobes subulate above the broader bases, the 

 lower ones nearly as long as the tube: corolla pinkish or purplish; standard 7-11 mm. 

 long: pods 3.5-4.5 cm. long, about 3 mm. wide, finely pubescent. Differs from C. 

 purpurea in the loose pubescence, the short upper calyx-lip and the blades of the 

 wing-petals which are auricled on one side only. 



In pine lands, southern peninsular Florida. 



Page 613, afer Robinia Boyntonii, insert : 



3a. Robinia Kelseyi Cowell. A spreading shrub or small tree 3 m. tall or less. 

 Twigs minutely pubescent: stipular spines short: leaves 1-1.5 dm. long; leaflets 7-13, 

 the blades oblong to lanceolate, 2-5 cm. long, acute or abruptly pointed, glabrous: 

 racemes loosely 3-7-flowered : calyx-lobes lanceolate, bristle-tipped: corolla rose- 

 purple, the petals less than 2 cm. long: pods oblong, 4^6 cm. long, very densely 

 glandular-bristly. Differs from JR. Boyntonii in the narrower leaflets, the glandular- 

 pubescent peduncle and rachis, the narrower calyx-lobes, the smaller corolla, and the 

 very densely bristly pods. 



On mountain slopes, North Carolina. Spring. 



Page 617, after Astragalus Carolinianus, add: 



5. Astragalus rnollissimus Torr. Plants copiously soft-pubescent, 6 dm. tall or 

 less. Stems short: leaves 1.5 dm. long or less; leaflets 19-27, the blades oblong, 

 elliptic or oval, 9-20 mm. long, abruptly pointed: racemes many-flowered: calyx 9-12 

 mm. long; lobes linear-setaceous, shorter than the tube: corolla violet-purple, 19-25 

 mm. long: pods ovoid, 11-21 mm. long, glabrous. Differs from A. Carolinianus in 

 the pubescent foliage and the smaller flowers with their short calyx-lobes and slender- 

 clawed standard. 



In dry soil, Nebraska and Colorado to Texas and New Mexico. Spring and summer.
