ADDITIONS AND CORRECTIONS. 



RUBIACE^!. 



26. GALIUM. P. 35, add, after the mention of Asperula : — 



ShebAbdia abvensis, L., according to Macoun, has been found wild in several places in 



Canada. 



G. dasycAepum, Nees, PI Neuwied Trav 11 (510), collected on the Missouri at the mouth 



of the Yellowstone, and briefly described, is wholly obscure. It is likened to Or. boreale. — The 



following is a somewhat anomalous species, perhaps to stand after G. multiflorum. 



G. Catalinense. Herbaceous perennial, hispidulous-puberulent or glabrate, unarmed : 

 stems erect, 3 or 4 feet high, mostly simple with short flowering branches which little sur- 

 pass the larger leaves ; its nodes usually with a tumid ring • leaves in fives or fours, narrowly 

 oblong, obtuse, mucronate, one-nerved (rarely by the union of two leaves 2-nerved), either 

 sessile by a contracted base or short-petioled ; at the insertion within bearing some obscurely 

 glandular bristle-shaped appendages : flowers on short slender pedicels, perhaps polygamous : 

 corolla white {2 lines in diameter) : young fruit sometimes naked and smooth, sometimes 

 beset with soft and straight bristles of about the length of the body. — Island of Santa Cata- 

 lina off Los Angeles, California, W. S. Lyon. 



COMPOSITE. 



To the Synopsis of Genera add, at the end of the Inuloidece, p. 59 : — 



63 \ DIMERESIA. Heads 2-flowered, homogamous. Involucre 2-phyllous. Pappus plu- 

 mose, early deciduous. 



Tkibe VIII. SENECIONIDE^, p. 79. An additional division is required for an 

 outlying genus, viz. : — 



Style-branches attenuate : involucre imbricated : often some chaffy bracts on the receptacle. 

 — Subtribe Liabece, Benth. & Hook. 



178 K BEBBIA. For the characters see p. 453. 



13. BRICKELLIA, Ell. 



B. Nevfnii, Gray. (Next to B. nacrophylla, p. 106.) White-tomentose, almost as in B. in- 

 cana, frutescent : leaves ovate or oval (larger ones only half-inch long): heads 30-40-flowered : 

 outer bracts of the involucre resembling the small rameal leaves, equally tomentose : other- 

 wise nearly like B. microphylla. — Proc. Am. Acad. xx. 297. — S. California, near Newhall, 

 Nevin.
