Phyllanthus compressus

Nov. 29'

Root of young plant kept in sol. 4 to 1000 for 21°, & then put into 10 per cent sol. of common salt examined today after about 20° immersion, & granular matter not at all removed & rootlets more transparent.— The rows of cells with granular matter very conspicuous & differ from those of E. peplus, in many adjoining in parts of roots & many empty or clear cells in other parts. In one spot I counted 13 granular, then one clear & then at least 9 granular.— In another place there were at least 13 rows of clear cells, & here plenty of root-hairs. The same row of cells when followed up is often interrupted by single clear cell or row of small cells; & so [converging] with the clear cells. In many cells the primordial utricle, owing to the salt, a little shrunk from walls. — Near tips of roots. rows

Looked, also, at roots kept for 20° in sol. of 7 to 1000 — granular matter in all rows near tip — Higher up some single cells & rows of cells clear, & here root-hairs arose — many dark brown spheres in parts, chiefly in endoderm-cells

of small brown spheres, in every row of cells — Invariably root-hair sprang from clear cells— whereas numerous adjoining granular cells no root-hairs — I saw, however, 2 cases of just commencing root-hairs — even papillæ, & here there was some granular matter in cells: this looks as if granular matter used in forming walls of Hairs; but then I carefully rexamined several clear cells with no root-Hairs near vascular bundle in endoderm many elongated cells with much brown granular matter — Also some milk tube with the hyaline aggregated grain, not numerous — Irrigated these specimens with Caustic Potash at 10° 40', examined 30th 8° 40' —

Granular matter still present in full quantity, but brown in exterior cells & in endoderm — & the agg. matter in milk-duct, rendered more orange.— Specimens, frayed now beautifully clear & it was even plainer than ↘

before that Hair-roots arise from empty cell.—

There was, however, one group of 4 papillæ or nascent, hairs arising from cells with the granular matter not, however, so abundant as in most cells. On other hand I saw nascent Hair arising from perfectly clear cells —) I saw row of very narrow, apparently inserted cells full of granular matter. — Does Potash dissolve only living granular matter; this specimen had been kept in the 10 per cent solution of salt?

N. B. Effects of Boiling water & alcohol lean to side of phenomenon being a vital one — These spheres in cells of root-caps look like dead chemical affair—
