ous cyanogenetic glucosid and were consequently harmless. The pro- 

 portion of prussic acid obtainable from L. arabicns is considerable and 

 varies from 26 per cent in the case of young plants to 32 per cent in 

 the case of those almost mature, when the yield of acid reaches the 

 maximum. (Adapted from Bulletin of the Imperial Institute, London, 

 vol. 1, p. 12.) 



51859. Lotus conimbricensis Brot. 



A gray-green, more or less hairy plant with decumbent, ascending, or 

 rarely erect thin stems and short-petioled leaves. The leaflets are mostly 

 ovate-lanceolate to obovate. The ovate stipules are longer than the 

 petiole and mostly longer than the leaflets. The small rose-colored 

 flowers are in one-flowered inflorescences. Found in sandy regions or on 

 grassy places on the Mediterranean coast, in the southwest parts of 

 Provence and the Riviera. (Adapted from Ascherson and Graebner, 

 Synopsis der Mitteleuropdischen Flora, vol. 6, p. 689.) 



51860. Lotus cytisoides L. 



A slightly hairy or nearly smooth plant with stipules shorter than those 

 of Lotus creticus. The corolla wings are broadly obovate, entirely cov- • 

 ering the keel. The pod, 3 to 5 centimeters long, is more or less com- 

 pressed, torulosely thickened, and straight or slightly bent. Found only 

 on the Mediterranean seacoast on rocky precipices. (Adapted from 

 Ascherson and Graehner, Synopsis der Mitteleuropdischen Flora, vol. 6, 

 aU. 2, p. 672.) 



51861. Lotus edulis L. 



A more or less hairy plant with ascending or erect, rarely decumbent, 

 branched stems, mostly 1 to 4 decimeters long. The gray-green leaflets 

 are obovate, rarely wedge-linear, and the stipules are broad ovate to 

 heart-shaped, oblique at the base, acute. The large yellow flowers are 

 in heads of one to three. Found in sandy areas in the Mediterranean 

 region only. (Adapted from Ascherson and Graebner, Synopsis der 

 Mitteleuropdischen Flora, vol. 6, abt. 2, p. 668.)

51862. Lotus filicaulis Durieu. 



A form closely allied to Lotus corniculatus var. major. It is dis- 

 tinguished by the elongated, thin, stiff peduncle. Native to Algeria.

 pdischen Flora, vol. 6, abt. 2, p. 682.) 



51863. Lotus gebelia Vent. 



An herbaceous plant, native to the Alps, which flowers all through the 

 summer. The robust and almost woody stem is branched, leafy, glabrous, 

 glaucous green, and one-fourth of a decimeter long. The ternate leaves 

 are subtended by bracts which resemble the subsessile, entire leaflets. 

 The flowers, 6 to 10 millimeters long, are at first crimson red, then pale 

 rose, and finally whitish streaked with rose. At night they fold down 

 next the petiole and are covered by the three leaflike bracts. The gla- 

 brous pods furnish a pleasantly flavored, nourishing food. (Adapted 

 from Ventenat, Description des Plantes Nouvelles et Peu Connues, CuV- 

 tiroes dans le Jardin de J. M. Cels, p. 57.) 



51864. Lotus jacobaeus L. 



A plant with an erect stem, linear leaves, and subterranean pods; 

 native to the Cape Verde Islands. 



51865. Lotus lamprocarpus Boiss. 



A plant native to the humid grasslands of Attica, with a robust stem 

 often 2 feet long diffusing into long branches. The lower leaves are 

 obovate, the upper oblong-acute. The yellow flowers are clustered in heads 

 of two or three. The narrow erect pods are shining gray, silky, and 

 smooth. (Adapted from Boissier, Diagnoses Plantarum Orientalium No- 

 varum, vol. 2, no. 9, p. S3. ) 



51866. Lotus ornithopodioides L. 



A hairy annual \sith branched, decumbent, or ascending, rarely erect 

 stems, mostly 1 to 3 decimeters long. The leaflets are wedge shaped at
