86 FLOWERING PLANTS OF THE RIVIERA 



of tube, often very red, as are also the petioles. Flowers usually purple but 

 varying from nearly white to deep magenta, numerous, in oval heads elongated 

 at maturity. Pods cylindrical, curved (25-35 mm - long), almost glabrous. 



Dry, hot banks and limestone.hills, extending to the mountains, 'local. April- 

 June. 



A. incanus L. Plant silvery with silky hairs, 3-8 in. high. Leaflets in 

 6-9 pairs, small, oblong or obovate, silky on both sides. Flowers purplish or 

 nearly white, 8-20 in ovoid heads on radical peduncles as long as the leaves. 

 Calyx hairy, with very short acute teeth. Pod cylindrical, arched, 15-20 mm. 

 by 4, covered with whitish down. 



Dry hills and arid places in the Var, local. April-June. 



A. sesameus L. Annual. Leaflets in 8- 10 pairs, oblong-elliptic, covered 

 with whitish hairs. Flowers small, bluish, 4-10 in dense obovate heads, sub- 

 sessile or on very short peduncles. Pods erect, 12-15 mm. long, nearly straight, 

 subcylindric, hairy. 



Dry, rocky places, rare. May. Near Nice and Le Pradet (Var). 



** Pods somewhat ovate, very hairy or woolly. 



A. pentaglottis L. Annual, whitish with hairs. Leaflets in 7-10 pairs, up- 

 turned, elliptic or oblong. Stipules broadly ovate. Flowers purplish-pink, small, 

 10-20 in dense oval heads on peduncles as long as the leaves. Pods 10-12 mm. 

 by 6 or 7 mm., erect, densely crowded, oval-elliptic, thick, covered with scaly 

 hairs. 



Dry, sandy places and arid hills. May-June. Frequent in the Var. 



A. glaux L., with 12-15 pairs of linear -oblong leaflets, and ovoid trigonous 

 pod, has been found at the base of Coudon (Herb. Rouy). 



A. purpureus Lamk. = A. hypoglottis L. See " Journal of Botany," 

 July, 1912, where C. C. Lacaita in an able and logical paper proves these to be 

 the same species ; with which decision we entirely agree, though hitherto 

 A. hypoglottis was usually considered the same as A. danicus Retz. which 

 grows on the chalk in the east of England. Stem spreading, hairy like the 

 whole plant with white spreading hairs. Leaflets elliptic or oblong, in 10-15 

 pairs. Flowers bright purple, rather large, in rather dense oval heads. Standard 

 oblong, emarginate. Calyx hairy, tubular, with irregular linear teeth. Pods 

 10 or 12 mm. by 5 mm. erect, ovate, somewhat cordate at base, hairy. 



Hot limestone hills and stony places, extending into the mountains. May- 

 July. 



A. vesicarius L. Plant silvery with silky hairs, 4-8 in. high. Root-stock 

 woody. Leaflets oblong, 4-7 pairs. Stipules lanceolate-acute, free. Flowers 

 large, violet with white wings, 5-10 in a rather loose globose raceme on long 

 peduncles. Calyx swollen in the fruiting stage, and almost hiding the pod, 

 woolly. In the Maritime Alps at Utelle above Grasse, etc., rare. May-June. 



A. aristatus L'Herit. = A. sempervirens Lam. Woody at base, and 

 forming great mats of spiny shoots. Stem very short, whitish pubescent. 

 Leaflets linear-oblong, 6-10 pairs with spiny petioles. Flowers white or washed 

 with lilac, erect, 3-8 in short, loose clusters, shortly peduncled. Calyx very 

 woolly, with setaceous teeth equalling the tube. Pods oblong, subtrigonous, 

 acuminate, glabrescent, seeds 8-12. 



Dry places in the mountain and Alpine region. June-July. Very rare in the 

 Var (Broves) and more frequent in the Maritime Alps. 



A. mnssiliensis Lam. = A. Tragacantha L. (part.). A spiny species 

 with subligneous root-stock. Leaves whitish-green with spinous petioles and 

 6-12 pairs of oblong leaflets. Flowers white, large, 3-8 in loose peduncled heads, 

 peduncles longer than in the last species. Calyx-teeth, lanceolate-obtuse. Pods 

 oblong, subtrigonous obtuse, mucronate, hairy, with four seeds. 



Maritime sands and rocks near La Seyne and St. Cyr in the Var. May- 

 June.
