Embriologycals researches in the thalictrum genus. — Embriology of Thalictrum angustifolium L. v. flavum L.
In this research has been studied the development of the female gametophyte of Thalictrum angustifolium L. v. flavum L.; it has been found a tetrasporic bipolarized type: the Pyretrum type, with sixteen nuclei.
The gametophyte is characterized by cellularization of every antipodal nucleus.
Besides this is a new type in the Thalictrum genus, supposing that in others species of this genus, has been recognized the Normal type.
The author supposes another type in this specie, probably a development of the tetrasporic tetrapolarized type, of which he will refer when the necessary elements emerge.
In this specie the microsporogenesis is simultaneous.
