TYPE 14. ORAINS COMPOTTND, OP PEW COMPONENTS OF EQUAL SIZE. 203 



PoicnlUla aurea Linn. {Rosacew.) Dry root-stock. — Separatod-grains, size 2 to 5ju; t\w smaller ones 

 rounded, the larger ones more or less polyhedral, and frequently with a small cavity. Most 

 of the compound grains have fallen apart; those still present are composed of 2 to 8 almost 

 equal components. Some more complex ones seem to have been present. Simple rounded 

 grains are also found. 



Alchemilla alpina Lima. (Rosacew.) Dry root-stock. — Compound grains, almost round to elongated- 

 oval, frequently somewhat irregular, consisting of 2 to 10 and 20 components which are 

 almost equal. Size aljout lifi. Separated-grains, size 2 to 4 and Gju; occasionally with a small 

 cavity. Some simple spherical and oval grains are also present. 



Geum urbanu7n Limi.; Radix caryophyllacoe. (Rosaceoe.) Dry root-stock. — Comj^ound grains almost 

 rounded or oval, rarely elongated-lanceolate, consisting of 2 to 8, rarely more than 8, com- 

 ponents which are equal and regularly arranged (a few are in one row). Sizes about 10^. 

 Separated-grains almost round or angular with rounded corners; size 1.5 to 5ix. Some simple 

 spherical grains are also observed, many of which appear at first sight to be simple prove 

 by closer observation to be divided by delicate lines. 



Geu7n montanum Linn. {Rosacece.) Dry root. — Compound grains of 2 to 8 different-sized com- 

 ponents. Size of separated-grains, 2 to 6/j. Simple almost round or oval grains are also 

 present. 



Crotolaria incana Linn. (Leguminosce.) Dry root. — Compound grains of 2 to 4 and 6 components 

 which are generally equal. Size about 14^. Separated-grains, size 2 to 7m; many with a 

 small cavity. Also simple, almost round grains are found. Starch rather scarce. 



Astragalus incanus Linn. {Leguminosce.) Dry root-stock {rhizome). — Compound grains of 2 to 4 

 almost equal components. Size about Ylfi. Size of the separated-grains 4 to 10/x. Simple 

 grains of incomplete formation are also observed. 



Lathyrus pratensis Linn. {Leguminosce.) Dry roots. — Compomid grains consisting of 2 to 8 com- 

 ponents of different sizes. Size about 16^. Separated-grains, size 2 to 9ju; occasionally 

 with a small cavity. Also solitary simple, almost round grains are present. Starch plenti- 

 ful. In the root-stock of the same plant the starch-grains are rather scarce. Size of 

 the compound grains 10m; of the separated-grains 1.7 to 6^. Also simple round gi-ains 

 are present. 



Lathyrus palustris Linn. {Leguminosce.) Dry root-stock. — Compound grains of 2 to 10 and 15 com- 

 ponents of different sizes. Most of the compound grains have fallen apart. Size about 24^. 

 Separated-grains, size 3 to 14^; instead of the hilum a small cavity is usually observed, which 

 in the oval forms is one-half and one-third eccentric. Starch plentiful, filling up the cells of 

 the cortex. 



Zornia angustifolia Smith. {Leguminosce.) Dry root-stock. — Compound grains of 2 to 10 and more 

 components of different sizes; size about 14/i. Size of the separated-gi-ains, 2 to 8^. Some 

 simple grains, almost round or oval, are also found. 



Alysicarpus ferrugineus Steud. {Leguminosce.) Dry root-stock. — Compound grains of 2 to 10 and 

 15m, almost equal components. Size about 16//. Size of the separated-grains 2 to l/j.. A 

 few simple rounded and oval grains are also present. Starch rather plentiful. 



Desmanthus virgatus Willd. {Leguminosw.) Dry root. — Compound grains of 2 to 4 and 6 components. 

 The majority have fallen apart. Size about 18^. Size of the separated-grains 3 to 10/i. Also 

 simple spherical and oval gi-ains are also found. Starch not plentiful. 



Encephalartos spiralis Lehm. {Cycadacece.) Dry embryo. — Compound grains of 2 to 4, rarely more 

 (up to 8), components which are usually equal and regularly arranged. Separated-grains 

 with 1 to 3 pressure facets, which are semi-spherical and also frequently somewhat oblique, 

 or they may be oval and often cut off obliquely at one end; instead of the hilum a small 

 cavity is observed from which short delicate fissures radiate, one-half to one-third eccentric; 

 usually one or two circular lamelte aroimd the hilum, as well as several incomplete lamellae 

 toward the distal end. Size of the separated-grains, 5 to 25 and 30^. Simple eccentric- 

 conical grains are also present. 



Ophirus cethiopicus Rupr. ; Ophirus papillosus Hochst. {Graminacece.) Dry endosperm. — Compound 

 grains when lying loose in the cell are almost round or oval ; when crowded they are angular 

 or even ixilyhcdral. They consist of 2 to 10 rarely 20 components. Siz(i about 1.5^. Sep- 

 arated-grains, size 2 to 8/i; usually polyhedral, sometimes with 1 curved surface and 1 to G
