world-wide repute ‘as Pennyroyal, the Mentha Pulegium of Lin- 
neus. In this error Dr. Kellogg, it must be admitted, led the 
way; for when the plant appeared to him he named it as a new 
Hedeoma, H. purpurea (Proc. Calif. Acad. v. 52). In working up 
the Labiate for the State Survey volumes, after having examined 
this plant minutely, Dr. Gray simply transferred it to the Cali- 
fornian genus Jficromeria, where, as he remarks, it is “ anoma- 
lous ;” and so it stands to-day in the Synoptical Flora, as MJ/icro- 
meria purpurea, Gray. It is abundant not only on that island in 
the San Joaquin River, whence Dr. Kellogg and Dr. Gray had it, 
but also in several parts of Middle California rather remote from 
that station; and not more than one species of mint, JZ. pzperita, has 
been more familiarly known in all countries during many centuries. 
A dozen years ago I found by the wayside, in Berkeley, a 
Cichoriacea new to me, and of which no account was given in the 
State Survey volumes, or in any other American book ; but, sus- 
pecting it of alien derivation, I soon found it to be Crepis virens, 
Linn., one of the most cosmopolitan members of its genus. But 
Dr. Gray twice mistook this plant for a new species, assigning it 
two new names, one in each of two distinct genera. It is his 
Malacothrix crepoides (Pac. R. Rep. xii. 49), and Crepis Coopert 
(Proc. Am. Acad. ix. 214); and it was a friendly fortune which 
permitted him to make this correction of a humiliating two-fold 
error with his own pen. Even Malva parviflora was by this 
author new-named JZ. obtusa when first it went to him from Cali- 
fornia. 
_ Iam said to have given the new name Paronychia pusilla to 
an obscure weed of Southern Europe, of which the real name ‘is 
Herniaria cinerea. It is the only instance in which I have honored 
an old weed with a new name; and as I have worked upon the 
Californian flora now nearly as many years as Asa Gray did, my 
record in this respect seems not likely to prove worse than his, 
to say the least.
