perience, little travel, and poor judgment but who do not hesi-

the beginning he would be pure cat, but if he met a dog which 
bit off a piece of his tail he would be catera, if the blood oozing 
out of his tail happened to stick it to his leg then he would be cat- 
erella, and if he got his tail all chewed off he would be catacauda. 
Let us take up Rydberg’s handling of Juniperus. He confines it 
to J. communis which he splits up into two species, and he makes 
the genus Sabina out of the rest. He of course cannot rest the 
the Juniperacee! So he rests Juniperus on the channeled and 
awl-shaped and not appressed leaves and sessile berry, and Sabina 
on the pediceled berry and scale-like and appressed leaves. Now ~ 
whenever the Virginian juniper grows in moist soil and shaded 
places and develops the awl-shaned leaves it is a Juniperus, but 
when it grows in drier soil and has only the scale-like leaves it is 
no longer a juniper but Sabina, but Rydberg does not say what 
it is when it has both kinds of leaves on the same plant as is 
genera all through his Flora of Colorado. In previous papers 
have shown how absurd is Rydberg’s attempt to split up Astrag- 
alus. s 
Now let us take up another class of genus splitters, whose.
