210 DIFFERENTIATION AND SPECIFICITY OF STARCHES. 



Nchnnbium lulcuin Willd. {Nchivibo lutca Pits.) Dry seed. Grains as in the preceding, tliough on 

 the whole somewhat broader. Ijength 20(U. 



Cistus vulgaris Spach. var. C. crclicus Linn. (Cislnccw.) Dry seed. Grains oval, elliptical, oblong, 

 blunt-triangular, and at times almost rcniform; two-thirds to almost as broad as long; the 

 broader ones compressed; no lamellse; usually a longitudinal slit is seen in the narrow aspect. 

 Length 21/i. 



Helianthemum wgyptic^im Mill. (Cistacew.) Dry seed. Grains oval, very often reniform or 

 roimded-triangular; one-half to two-thirds or seldom almost as laroad as long; slightly 

 compressed; no lamellse; with an oblong cavity, or a longitudinal slit on the narrow side. 

 Length 18ju. 



Lechia thymifolia Mich.x. (Cistacece.) Dry seed. Grains rounded-oval to elliptical, often broadly 

 triangular or almost reniform, two-fifths to almost as broad as long; the broader ones slightly 

 compressed; no lamellie; usually with a longitudinal slit which appears narrower, but more 

 marked when seen from the narrow side. Length 12fi, rarelj' 20/x. 



Bixa orellana Linn. (Bixaceoe.) Dry unripe seeds. Grains rounded-oval to elliptical, sometimes 

 blunt-triangular and almost reniform; the long ones two-fifths to one-half as broad as long, 

 and the shorter ones as broad as long; the broader ones compressed about two-thirds of their 

 width; few delicate or no lamella; with a long slit-like cavity which is more or less distinct 

 in both aspects ; or with a narrow slit and short transverse fissures seen only from the narrow 

 side. Length 30 and 3LV. 



Mangifera species (probably M. indica) Linn. (Avacardiacew.) Dry cotyledons. Grains oval to 

 oblong, sometimes blunt-triangular, rarely almost rcniform; two-fifths to as broad as long; 

 the broad ones compressed; no lamella; often with a slit-like cavity which is usually more 

 distinct in the narrow aspect, and from which frequently very delicate cross-fissures radiate. 

 Length 30^- Some doublets among them. 



Anacardium occidentale Linn. {Anacardiacce.) Dry cotyledons. Grains spherical or ellipsoidal, often 

 on one margin curved or even plano-convex; two-thirds to as tjroad as long; the widest ones 

 sHghtly compressed; no lamellae; the spherical grains have a small central cavity, and the 

 oval ones an indistinct longitudinal slit. Length lOyu. Among them compound grains of 2 

 to 3 part-grains. 



Lotus edulis Linn.; Krokeria edulis. (Leguminosce.) Dry cotyledons. Grains spherical-oval or rcni- 

 form; three-fifths to almost as broad as long; the broad ones compressed, the narrower ones 

 sHghtly compressed, few delicate, sometimes indistinct lamellae; a delicate longitudinal slit 

 with very indistinct radial fissures in the broad aspect; the slit as well as the radial fissures 

 are more marked in the narrow aspect. Length 45;u. 



Caragana altagana Poir. {Leguminosce.) Dry cotyledons. Grains rounded or oval; three-fourths to 

 equally as broad as long; slightly compressed; occasionally with a longitudinal slit on the 

 narrow side. Length 8;u. 



Caragana arboreseens Lam. (Leguminosce.) Dry cotyledons. Grains rounded or oval; three-fifths 

 to almost as broad as long; slightly compressed; with indistinct cavity seen on the broad 

 aspect; on the narrow side a distinct longitudinal slit. Size 8 to lOyu. 



Cicer arietinum Linn. {Leguminosce.) Fresh and dry cotyledons. Grains almost spherical to ellipti- 

 cal; twice as long as thick; with few, very indistinct lamella and an oval or oblong hilum; 

 dry, with a longitudinal slit and delicate radial fissures. Length 30/i, thickness 23yu. Among 

 them compound grains of few equal-sized part-grains (see type 14). 



Pisum sativum Linn. {Leguminosce.) Dry cotyledons. Grains oval to almost reniform, and blunt- 

 triangular; half to almost as broad as long; the l)road ones compressed. Lamelke distinct, 

 usually 5 to 7; an indistinct cavity with delicate radial fissures is seen on the broad side; a 

 marked longitudinal slit on the narrow side. Length 65/j. A few doublets are found among 

 them. 



Ervum lens Linn. {Leguminosoi.) Fresh and dry cotyledons. Grains oval to triangular with rounded 

 corners; half to almost as thick as long; with 2 to 3 lamella;; and ovate or oblong hilum; dry, 

 with delicate radial fissures in the broad aspect, and with a distinct slit in the narrow asjiect, 

 but rarely with cross-fissures. Length 40/u, width 30^. According to Payen, the length is 

 67m- Doublets with equal parts are often found among them (type 14).
