 underlying cells. — IVc, lysigenetic canal with its surrounding cells. — V, 

 Dalea alopecuroides : sections from different parts of seed. — VI, Petalostemon 

 candidus: thick-walled cells of the endosperm below the nutrient layer. — 

 Vlb, embryo with protein grains and fat. — VII, Dalea laxiflora: thick- 

 walled reserve cellulose of endosperm. 



Plate XIII. — I, Indigofera leptosepala: endosperm differentiated into 

 three parts. — la, embryo. — II, Oxytropis detlexa: cells of nutrient layer 

 thick-walled. — III, Astragalus mexicanus: separated Malpighian cells with 

 well-developed cuticularized layer and cuticle. — Illb, surface view of the 

 Malpighian cells. — IV, Oxytropis Lamherti: cells of aleurone layer thick- 

 walled. — Y, Astragalus canadensis: cells of aleurone layer large, followed 

 by the gelatinous endosperm. — Vb, cell-cavity with chromatophore after 

 the action of sulphuric acid. 



Plate XIV. — I, Bobinia Pseudacacia: — la, general view of cross-section 

 of the seed showing different layers in position. — lb, portion of upper 

 part of Malpighian cell greatly magnified to show cuticularized layer c with 

 pore-canals projecting into cell. — Ic, Malpighian cell showing light line in 

 upper part. — Id, young Malpighian cell greatly magnified. — le, osteo- 

 sclerids greatly magnified, showing longitudinal pore-canals. — If, cells of 

 endosperm with thick-walled reserve cellulose. — II, Wistaria frutescens: 

 general view, broad cuticularized layer above the light line ; chromatophores 

 in upper part of cells. — lib, section through outer part of embryo; starch 

 grains in the cells; the interior large, and showing intercellular spaces. — 

 lie, lower part of nutrient layer and mycotic layer. — lid, an oblique view 

 of the Malpighian cells. 



Plate XV. — IjDesmodium canescens: cells of embryo without starch; nu- 

 trient layer differentiated into two parts. — II, Desmodium strictum : three 

 rows of cells of the nutrient layer, followed by the aleurone, and reserve 

 cellulose of the endosperm. — Ilia, Desmodium canescens: superior face of 

 cotyledons; small epidermal cells and palisade parenchyma below; cells 

 contain fat and aleurone grains. — Illb, Lespedeza Stuvei: embryo cells of 

 lower face. — IIIc, endosperm. — IV, Aeschynomene hispida : nutrient layer 

 differentiated into two parts; cells of the aleurone layer smaller than those 

 of the reserve cellulose of the endosperm. — V, Lespedeza virginica: large 

 chromatophore in the upper part of Malpighian cell; cells of aleurone layer 

 smaller than those of the reserve cellulose. —VI, Glycyrrhiza lepidota: nu- 

 trient layer well developed ; aleurone cells large ; thick-walled cells of reserve 

 cellulose below. — VII, Eedysarum boreale: well developed cuticularized 

 layer above the light line; large chromatophore in the Malpighian cell; 

 epidermal cells of the embryo large. 



Plate XVI. — I, Vicia sativa: minute pore-canals below the cuticularized 

 layer; upper part of the Malpighian cell light colored with a large chromat- 

 ophore ; osteosclerids with longitudinal pore-canals. — II, Vicia sativa: Mal- 

 pighian cells irregular on surface; cross-section of spiral ducts in the nu- 

 trient layer; epidermal cells of the embryo without starch. — lib, starch 

 grains which have undergone disintegration. —Ill, Lathyrus maritimus:
