Dr. Asa Gray (Proc. Am. Acad. viii. 370), after remarking as 
to the placing of the genus Scutellaria in a subtribe, goes on to state 
that “ The winged nutlets of Perilomia, however, are curiously imitated 
in one or two species of Scutellaria, only obscurely so in S. parvula, 
as has been noted by Dr. Torrey, . . . but strikingly in S. ner- 
vosa, Pursh, and in a Japanese species not otherwise very similar 
" The presence of this membranaceous wing, together 
with a reputed difference in shape of the corolla, is used as a basis 
of separation of the above-mentioned genus Perilomia from Scutellaria 
by Humboldt, Bonpland & Kunth (Nov. Gen. & Sp. Amer. ii. 326). 
Prof. Fernald (Ruopora, xxiii. 85), after examining sheets of the Old 
World S. galericulata and of the North American form, which for 
many years had passed as 5. galericulata, came to the conclusion that 
the Old World plant is really not found as such on this side of the 
Atlantic, but that it has a closely related representative here. This 
was demonstrated chiefly by nutlet-characters, the exact significance 
of which will be clarified in the sequel. 
These facts have combined to indicate that perhaps a critical 
inspection of the group in question, from the standpoint of the fruit, 
might serve to throw light on, if not to clear up, some well known 
taxonomic difficulties existing here. From an examination of over
