80 PROCEEDINGS OF THE AMERICAN ACADEMY 



80 striking, that, since the collector's original tickets inilicute at least 

 three separate stations and different dates of gathering the specimens, 

 I was disposed to regard them as distinct species ; but a few scattered 

 hairs on the glabrate form render the separation unadvisablc. The 

 larger leaves of this little plant are 3 lines, the smaller only 2 lines 

 in length. Capsule half a line at most in length. 



Galium. The revision of this genus for the North American 

 Flora brings in few additions and few changes that have not already 

 been indicated. The following are the principal. 



Galium Texensk is a name proposed to take the place of G. Cali- 

 fornicum, var. Texaniim, Torr. & Gray, Fl., whicli was later referred 

 to the Mexican G. uncinulatuin. Our plant better accords with the 

 character of G. obstipum, Schlecht., but still seems to be distinct from 

 the Mexican species, one or more, to which it is nearly related, and it 

 is an annual. The form Texense is used because Scheele introduced a 

 G. Texanum, founding it on a mere form of G. viryutum, and badly 

 describing it. 



Galium Kamtschaticum, Steller, is a species allied to G. cir- 

 ccEzans, which ranges from the mountains of Lower Canada (where it 

 was recently collected by Dr. Allen of New York), and the higher 

 mountains of New England (where it is known as G. LitteUii, Oakes, 

 G. circcBzans, var. montanum, Torr. & Gray), to those of Oregon and 

 "Washington Territory, Unalaska, Kaintschatka, and Sagalien. One 

 cannot understand why Ledebour referred this plant to G. ohovatiim, 

 II BK., a species figured as having unicostate leaves and inhabiting 

 Equatorial America. 



Galium Arkansanum. Tliis is G. latlfoUum /3, Torr. & Gray. 

 It has, indeed, the flowers and inflorescence of that most distinct 

 species, but has more scabrous-hispidulous and narrow tmicosfafe 

 leaves. Besides Dr. Engelmann's specimen, it is known to us by a 

 linear-leaved form collected at the Hot Springs of Arkansas by Dr. 

 Foreman of Washinjrton. 



Galium Mattiiewsii. Trichogaliiim, inter G. angustlfoUum et C. 

 stellatum, glabrum, la;ve, frutescens ; caulibus paniculato-ramosissimis ; 

 foliis rigidis oblongo- vel ovato-lanceolatis parvis, superioribus apice 

 cuspidato-acutatis ; setis fructus immaturi rigidulis breviusculis. — 

 Arid district in Inyo Co., California, Dr. Matthews. 



Galium Bolanderi, Gray, Proc. Am. Acad. vii. 350, proves to 

 have been founded on a male plant of the white-berried species which, 

 collected in fruit by Sir Joseph Hooker and myself, was published as 

 G. margaricoccum, Gray, 1. c. xiii. 371.
