Oxalis (Greenhouse/ grown out of doors)
With large leaves & concentric purple mark on leaves— flower pale purple.— syringed & leaflets closed closed to certain extent, like O. acetosella. —
May 2d Oxalis with Coppery foliage & yellow flowers— I syringed 2 lots of plants in Hot House & one lot in pot showed slight signs of depression of leaflets. The other showed no signs.— I then put pot outside of H. House — rather cold day & leaves after 3/4 hour I found all considerably depressed — so cold seems efficient. — I took plant into Study but leaves never expanded & at night it went beautifully to sleep with each leaflet inwardly folded
