17 Plantago

18 Prunella vulgaris (Commonist) Kept 5-6 weed a very few germinated

19 20 Cerastium vulgatum did not germinate. Kept do.

June 1— 1857.  Poa & Tresetum very abundant Ranunculus & Dandelion vigorous.— By careful examination I f one 1/2 dead leaf of Clover & Achillæa— not one daisy— 1/2 dead Cerastium, which all utterly died soon (Bears a cropping by cattle in Pampas.) All the grasses were present & extremely vigorous— so that luxuriant growth has killed nine species of plants.

May 30 1858)  Ranunculus Dandelion & Grasses. Small bare patches had appeared in spring & on them I noted many seedlings coming up, but by this time all had perished: thus confirming my experiment of sowing seeds.

Trisetum, Poa, Lolium predominant  Holcus increased.— Buttercup & Dandelion very vigorous—
