June 18th 8O — Seeds which had been clasped by Drosera on Jun 6th & 8th & placed on damp sand on Jun 10th
F /
7 Cabbage seeds planted & only 2 have germinated A third has partially germ it has end of radical rotten & edge of cotyledon(which are of unequal size) brown & black & decayed— Evidently killed by secretion & midrib of one cotyledon brown (The other 4 cabbage seed rotten)
5 Cress seeds. 1 germinated, — 4 dead ' it was very curious that 2 protruded radicles on the leaf of Drosera, but died when placed on sand
2 Radish, one germinated, but much delayed & the exterior of both cotyledons oddly whorled with purple with the . edge kill blackened & in parts withered. — radicles crooked & displaced, with extremely small with hardy any absorbent hairs
I opened the other radicle which was evidently dead— & the cotyledon blackened in great patches evidently where seed has lain on secretion
