ON SOME SPECIES OF CHERASTIUM. 
By Frep, Townsenp, M.A. 
Tue late M. Ch. Grenier, in a supplement, lately published, 
of his ‘ Flore de la Chaine Jurassique,” has given his views of the 
synonymy of Cerastium po: Curt., together with a description 
of the species and an arrangement of its supposed varieties. As this 
work may not be peucrally. pana I here give a translation of 
his Tamarks on the species, and appe me of my wn 
“C. pummum, Curt. (1778); C. laude, Loi (1805) ; C. gluti- 
nosum, Fries (1817), non H.B. K.; C. obscurum, Cheub. (1821). (See 
the synonomy at the end of this article. 
_“* NOTE on C. pumilum, Cart.—M. Babington has established the 
identity of C. pumilum, Curt., C. glutinosum, Fries, and C. obscurum, 
Chaub. On the other hand, in my monograph, of the Cerastia, I have 
shown the identity of C. alsinoides, Lois , and C. glutinosum, Fries ; C. 
aleinosdes i is therefore only a synonym of °C. pu 
ibe LC. alsit 
as distine t species (dubitanti ag animo, p. 35). The two descrip- 
tions should therefore be uni o the synonyms. e same 
should be done with respect to C. Gictaasen and C. pumilum of the 
‘¢ Flore de France.” But a place must be reserved for the varieties of 
my C. pumilum, which I shall presently describe, and for C. aggre- 
gatum, Dur., which should be retained as a net es. 
first mention of C. glutinosum, Fries name was first published 
by Fries in 1817, in the first ere 7 his “ Novitiz,”’ w Cc. 
in company 
aout (?) after the pa name, 
C. Grenieri et pallens Schultz, may be added to the above 
scariose of its bracts. I propose, therefore, to retain it as a 
variety, if not as a species. In like manner I Leis Sey ge retain C. 
litigiosum, De Lens, as a variety; this is distinguished by the petals 
being twice as long as ses sepals. a
