Clotzsch [Klotzsch] says in German work that no crossed Pinus silvestris [sylvestris] & Nigricans, Quercus robur & pedunculata, alnus glutinosa & incana, Ulmus campestris & effusa, seeds from these & from their true parents were sown at same time & place. Now after 8 years the hybrid trees are 1/3 larger than the others.

p. 503. M. Fabre describes the two kind of flowers & pods of Vicia amphicarpa one subterranean & the other aerial, the former flowers seed perhaps rather most fertile. By uncovering & covering the branches can convert one form into the other, yet flowers differ much. Arachis hypogaea & trifolium subterraneum bury their flowers after fertilization, but he knows of no other case of flowers formed in the earth except the above Vicia.

M. Cosson cited case of Latherus amphicarpus

[182v]

as having subterranean flowering branches; the seeds from both kinds of Lathyrus produced similar individuals. Has found subterranean flowers with Orobus saxatilis (Mem. Latherus nissodia & other cases of Dimorphis in Leguminosæ)
