Pees 2, Wisconsin, Lapham ; and 5, Californian Mountains, Bolandes It also occurs on the Pacific coast at least 
as far south as the Datles of ae Columbia, Lyall; J. ergata Mey. Junc., p. 10, is a depauperate northern form.

n salt-marshes and in saline sandy soil near the coast of ae Francisco Bay, Bolander, Kellogg, Hb. norm. 6.— 
Flowers July and August. — The plant certainly stands close to J. Balticus, but may always be recognized by the char- 
acters given above, and the habit is quite different. The stems of the larger specimens are much thicker, often 25-3 
lines in diameter, and softer; inflorescence as in all its allies very changeable, sometimes loose but more commonly 
compact and with gray 1- ra branches ; flowers larger than in J. Balticus, 2}-3 lines long, and capsule from an 
oval base pointed; 8 —0.37 and in Chamisso’s Chilian specimen even 0. 40 line long, smoothish or usually 
somewhat Bijeilbaed: ais ewe socseapdusStag with the cells of the epidermis, which when removed leaves the seed, 
very similar to that of J. Balticus, marked with a distinct but delicate transverse reticulation ; something of: this is 
also seen on the inside of the detached epidermis, perhaps from adhering parts of the second layer of cells. J. Balticus 
has usually smaller flowers, 1}+-2 lines long, only in North Pacific specimens have I seen them nearly as large as in 
. Lesueurtt; its capsule is more prismatic and abruptly mucronate, the seeds of the same size, but (evidently 
owing to the greater eee « of the epidermis, which otherwise exhibits the same structure) always marked [491] 
with regular transverse reticulat

South Carolina, 8, and an unusually slender one, 9, from the Californian Mountains, where the common one also grows. 
The western botanists find in the salt-marshes near San Francisco a brown-flowered variety, which may be distinguished 
as var. brunneus ; giktagts nomena looser and fastigiate, Herb. norm, 10, or more compact, ib. 11: other differ-

green lowers 13 a low (8-15 inches high) rigid form with a more compact darker colored inflorescence.

Psand abundantly by ih Smith, Porter and see on sodiadeay Sigy Pennsylvania (Herb. norm. 15), 
where it had been discovered by Mr. Smith a year before ; also in Rausch’s » Lebanon county. — The very com- 
plete specimens sent by these gentlemen enable me to ‘ania the history of Toe thus far, very rare plant, which 
proves to be intermediate between J. Balticus and J. filiformis, with the rootstock of the former and the inflorescence 
of the latter, and with almost the seeds of J. arcticus. Seeds 0.32-0.38 line long, with short and broad appendages 
and a distinct rhaphe, distinctly but somewhat irregularly reticulate and partly also lineolate ; epidermis easily removed 
after eigen. 
J. setaceus: a larger and a smaller form from South Carolina have been distributed in Herb, norm. 14 by Mr. 
Ravenel ; eter tal of the creeping rhizome short, stems cespitose. 
Page 445. J. arcticus is more closely allied with J. Balticus and Smithii than with J. Drummondii. More speci- 
mens obtained from the coasts of the — Pacific show that the var. Sitchensis is not rare there, and extends to Kam- 
schatka ; its characters hold their own 
J. Drummondii, Aaa Alps, Sade. Hb. norm. 16. 
e 446. J. Parryi: a form with the interior sepals obtuse and much shorter than the exterior ones, which are 
as long as + dc was found by Mr. Bolander on alpine meadows, California 
- J. stygius, also on the north shore of Lake Superior, 0. B. hed it seems rare everywhere, [492] 
so that 1 adore a yet been able to obtain it in sufficient quantity for the Herb. n 
J. Vaseyi. While I was deploring the destruction of Dr, Vasey’s original baaiig: Rev. Mr. Holzer and Dr. Bige- 
low discovered this species in abundance in damp open woods on both sides of the river near Detroit, growing together 
with J. Greenii. Dr. Bigelow’s fine specimens are distributed in Herb. norm. 17. Many of them are 2} feet high.
