Mr. MiiiTiit considers his N. nodtih^a probably n (Iccp-wMtcr

This is the largest species in the genus : it either varies much, 

 however, in size and proportion, or eli^e the following forms 

 should be considered distinct. As they all possess the revolv- 

 ing dark-colored lines, I prefer to consider them as simple dwarf 

 varieties.

Broadly ovate, approaching N. mtUabilis, L. in form.
