 on such problens of nomenclature; I; also, became only last Win- 

 ter aware of severall striking, unf ortunately sterile^f orms of Lern -

 am convinced, that^by further delaying my work,I not only could- 

 fill in several known gaps and also augment my notes, but also

 Callitriches from California, and did probably annouce their re-

 some more will 1 augment them., I have ordered the new edition of A. 

 Greyy and am curious about it. W. brasiliensi s also shows some dif-

 of it, which is available to me; if this is oorrect for all forms,, 

 is, of course, a big question. The back-surf ace is less raised 5 with 

 brasiliensis than with our arrhiza . , The simplest and least perfect 

 structure is definitively the columbiana . Her back surface is al-

the form of an ellipse very closely. Its texture is much länger-
