Malpighian cells. — IX, Glycine hispida. — IXb, embryo; fat globules /, and 

 protein. 



Plate XXXIII. — I, Vigna Catjang: lb, embryo. — Ic, surface view of 

 osteosclerids. — II, Tamarindus indica : parts of nutrient layer and embryo 

 shown; cells of the embryo thicli- walled. — III, Lens esculenta: surface view 

 of Malpighian cells; somewhat irregular on surface. — Illb, a few cells of 

 the embryo. — IV, Dolichos Lablab. —V, Glycine hispida: a', epidermal cells; 

 aleurone grains in parenchyma cell; el lower surface, eu upper surface with 

 palisade cells. 



Plate XXXIV. — I, Lathyrus venosus: Malpighian cell immediately after 

 the addition of chlor-iodide of zinc; light line, cuticularized layer and the 

 walls of osteosclerids take on a blue color; starch grains blackish. — II, 

 Gleditschia monosperma: thick-walled reserve cellulose cells of endosperm 

 treated with chlor-iodide of zinc color blue; the contents, yellowish. — III, 

 Vigna Catjang: Malpighian cell treated with sulphuric acid and iodine. — 

 IV, Desmodium canadense: treated with sulphuric acid and iodine. — V, 

 Cassia nictitans: treated with ferric chloride. — VI, Nelnmho lutea: 

 chlor-iodide of zinc colors the walls blue; phloroglucin and hydro- 

 chloric acid give no reaction, the cell retains its normal color. — VII, 

 Bhynchosia phaseoloides : Malpighian and osteosclerid cells treated with 

 ferric chloride, give the reaction for tannin; light line remains unchanged. — 

 VIII, Canna indica treated with phloroglucin and hydrochloric acid, no 

 reaction. — IX, Gleditschia monosperma: Malpighian cells treated with chlor- 

 iodide of zinc, walls colored blue, the wide light band in upper part of cell, 

 straw-colored. — X, Tropaeolum majus: thick- walled cells from cotyledon 

 treated with iodine color blue, the reaction for amyloid. — Xf, Geranium 

 caroliniaman : treated with phloroglucin and hydrochloric acid ; Malpighian 

 cells retain their normal color; the cells below slightly lignifled. — XII, 

 Marsilia quadrifolia: no reaction on the addition of phloroglucin and hydro- 

 chloric acid; walls color blue with chlor-iodide of zinc. 



Plate XXXV. — I, Dracocephalum parvijlorum: Malpighian cell treated 

 with phloroglucin and hydrochloric acid, walls strongly lignified, — II, 

 Sterculia heterophylla: lower portion of wall strongly lignifled. — IIIi 

 Lathyrus venosus: Malpighian cells natural color; starch grains after the 

 addition of iodine. — IV, Ceanothus americanus: Malpighian cells ti'eated 

 with phloroglucin and hydrochloric acid; walls strongly lignifled. — V, 

 Gossypium herhaceum: lower part of cells strongly lignified — VI, Sicyos 

 angulatus: Malpighian cells strongly lignifled, except the light line and 

 upper part of cell. — VII, Ipomoea tuba: treated with chlor-iodide of zinc. — 

 VIII, Ipom,oea tuba : treated with phloroglucin and hydrochloric acid; cells 

 very slightly lignifled ; walls below the Malpighian layer lignifled. — IX, 

 Vigna Catjang : tracheid island and Malpighian cells lignifled. — X, Vigna Cat- 

 jang: single Malpighian cell from lateral part of seed, lignified. — XI, Tilia 

 pubescens : lower part of cell strongly lignifled ; light line remains unchanged 

 when treated with phloroglucin and hydrochloric acid. — XII, Baptisia 

 leucantha: Malpighian cells slightly lignifled, the osteosclerids less so.
