490 TRANS. OF THE ACAD. OP SCIENCE. 



Durand informs me, undoubtedly of European origin ; the 

 only certain locality in North America is the- Californian 

 one. 



Pag. 439. J. Rcemeriamis. The New Jersey locality 

 rests on the doubtful authority of Pursh; I have seen no spe- 

 cimens collected farther north than Wilmington, N. Carolina, 

 whence Mr. Canby has sent it, Hb. norm. 1. 



Pag. 441. J. Balticus has been distributed in Hb. norm. 

 4 from Pennsylvania, Porter; 3, Michigan, Bigeloic ; 2, Wis- 

 consin, Lapham, and 5, Californian Mountains, JBolander. It 

 also occurs on the Pacific coast at least as far south as the 

 Dalles of the Columbia, Lyall ; J. Haenkei, Mey. June. p. 10, 

 is a depauperate northern form.

 (1863): rhizomate repente; caulibus (2-3-pedalibus) crassio- 

 ribus mollibus saape fistulosis ; paniculaa ramis secundis ; flo- 

 ribus (bruneo-striatis) majoribus ; sepalis lanceolatis exterio- 

 ribus acutissimis interiora obtusa paulo superantibus, omnibus 

 supra capsulam ovatam vix obtuse angulatam acutam brevio- 

 rem vel a;quilongam conniventibus; antheris 6 late linearibus 

 filamento brevissimo quadruplo quintuplo longioribus ; semi- 

 nibus magnis ovatis obtusis breviter vel vix apiculatis tenuis- 

 sime irregulariter reticulatis vel laaviusculis. — J. Balticus,

In saltmarshes and in saline sandy soil near the coast of 

 San Francisco bay, Bolander, Kellogg, Hb. n. 6. — Fl. July 

 and August. — The plant certainly stands close to J. Balticus, 

 but may always be recognized by the characters given above, 

 and the habit is quite different. The stems of the larger spe- 

 cimens are much thicker, often 2£-3 lines in diameter, and 

 softer; inflorescence as in all its allies very changeable, some- 

 times loose but more commonly compact and with strikingly 

 1-sided branches; flowers larger than in J. Balticus, 2^—3 

 lines long, and capsule from an oval base pointed ; seeds 0.30 

 -0-37 and in Charaisso's Chilian specimen even 0.40 line long, 

 smoothish or usually somewhat reticulate, the network cor- 

 responding with the cells of the epidermis, which when re- 

 moved 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 J. Besueurii / its capsule is more prismatic 

 and abruptly mucronate, the seeds of the same size, but, evi- 

 dently owing to the greater transparency of the epidermis,
