Berula* angustifolia, Koch. {Slum angustifolium, L.) — San Luis Val- 

 ley, Colorado, in hot springs, the temperature of which is 80° Fahr., and 

 in spring water at Fort Tejon, Cal., where the water has a temperature of 

 62° Fahr. In neither of these locations was there much of a yearly- 

 variation in temperature of the water, yet in one instance, as in the other, 

 the plant grew luxuriantly, the difference in the temperature of the water 

 at the two places being 18° Fahr. (732, 262.) 



Sium cicutj3folium, Gmelin. (Apium lineare, Benth. & Hook ) — San 

 Luis Valley, Colorado (730, 732). 



Ctmopterus alpinus, Gray. — Low annual shoots 2-5' high, from a 

 perennial root ; leaves bipinnatisect or bipinnate, segments 2-4" long, linear, 

 acutish, glabrous, or very minutely puberulent ; scape as long as or exceed- 

 ing the leaves; involucels 5-7-parted, segments linear or lanceolate, as 

 long as the flowers; calyx-teeth conspicuous, subulate; fruit thickish winged, 

 with the marginal ones a little wider than the others ; vittse one in each 

 interval and two on the commissure, all small. Flowers small, yellow. — I have 

 taken the character of this fruit from No. 213 of Hall and Harbour. The 

 material, moreover, is very scantjr. If, however, the specimen examined 

 bj^ me is fairly a representative one, the resemblance between it and 

 (Enanthe is too obvious to escape attention, especially when we remember 

 that with the other peculiarities it has no carpophore. — Griffith's Peak, near 

 Georgetown, Colo., at 11,500 feet altitude (725, 731) ; also accredited by 

 Porter to Mount Lincoln, Colorado, at an elevation of 13,000 feet. 



Ctmopterus glomeratus, Raf. — 3-8' high; caudex 1-2' high, branching 

 from the summit ; peduncles shorter than the leaves ; leaves ternately 

 divided, deeply bipinnatifid, on long petioles, which are dilated at base. 

 Umbels on very short rays ; involucels palmately parted, unilateral and 

 sometimes coherent with the rays of the umbellets ; flowers white ; fruit in 

 my specimen, No. 210, of Hall and Harbour, with marginal wings thin and 

 expanded and with the dorsal ones only a little less so. I must confess my 



* Berula, Koch. — Calyx-teeth minute. Stylopodium conical and styles short. Fruit nearly glo- 

 bose, with a broad commissure, emarginate at base, the ribs nerve-like, not raised above the thick 

 epicarp; oil-tubes numerous and contiguous, surrounding the terete seed. Carpophore 2-parted, very 

 slender. — A smooth, perennial aquatic ; leaves pinnate and serrate ; involucres and involucels of several 

 leaflets; flowers white.— Fl. Cal., p. 260.
