PRIMULACEiE. 



Trientalis europaea arctica (Fiscb.) Ledeb. Fl. Eoss. iii, 25 (1847); T. arctica 

 Fiscb. ; Hook. Fl. Bor. Amer. i, 121 (1830). Tlie range given witb Lbe original descrip- 

 tion is from Sandy Bay, in Clarence Straits, to Uualaska, and in Kamcbatka. 



Between tbo Mission and Cape Pbipps, June 1 (No. 10); of fre(i[ueut occurrence in 

 tbe spruce forest. 



Glaux maritima L. Sp. PL i, 207 (1753). Type locality Euroi)e. 



On tbe mainland near tbe Mission, June 19 (No. 32) ; growing in patcbes on tbe 

 beacb just above tbe line of bigb tide. It occurred also on Kbantaak Island at tbe 

 bead of Port Mulgrave. 



GENTIANACEiE. 



Gentiana amarella L. Sp. PI. i, 230 (17.53). Type specimens from Europe. 



Cape Pbipps, July 23 (No. 72), and Disencbantment Bay, August 11 (No. 104); at 

 botb points growing on tbe beacb. Two forms are represented in tbeso two num- 

 bers, tbe best disposal of wbicb, in tbe present state of our knowledge concerning 

 tbe varieties of G. amareUa, is to refer tbera to tbat species without a varietal desig- 

 nation. No. 72 has purplish foliage and stem, blue flowers, and a deeply cleft calyx, 

 tlie narrow lobes of wbicb are not more than one-half as long as the corolla. No. 104, 

 while very similar in form and size, has green herbage, yellow flowers, and a calyx 

 with more foliacetms divisions, the larger commonly two-thirds to three-fourths as 

 long as tbo corolla. 



Gentiana platypetala Griseb. Gent. 191 (1839). The type specimens were col- 

 lected on tbe island of Sitka during tbe second expedition of Kotzebue in tbe early 

 part of tbe present century, and none have been reported since. 



Disencbantment Baj', August 12 (No. 108). It lias been impossible to compare ours 

 with the original sj)ecimens, yet from Grisebach's description we appear to have 

 the same plant. It closely resembles small specimens of G. calycosa, the stems 

 being 15 to 22 cm. high and bearing to 10 pairs of ovate-oblong, obtuse or bluntly 

 acute leaves. Each stem is terminated by a single sessile flower iuvolucrately sur- 

 rounded by 2 or 3 pairs of leaves, the inner reduced. The calyx, Avhich is about 

 one-half as long as tbe tube of the campanulate blue corolla, has a 8i)athaceou8 

 membranaceous tube 10 to 14 mm. long, which usually spreads open along two oppo- 

 site lines nearly to the base, the free margins being thin, scarious, and apparently 

 not torn. The calyx lobes proper are minute, lanceolate, acute, herbaceous organs 

 about 3 mm. long. Tbe corolla lobes are conspicuously narrower at their insertion, 

 broader than long, and abruptly acuminate, while the plaits in tbo sinuses are tri- 

 angular, broader than bigli, and acute or emarginate. 



Menyantlies trifoliata L. Sp. PI. i, 145 (17.53). Type locality European. 



Kbantaak Island, .June 20 (No. 39): coiumon in fresh-water ponds, growing both 

 in tbe water and on the adjacent Avet soil. 



HYDROPHYLLACEiE. 



Romaiizoffia sitchensis I'ong. Veg. Sitch. 158 (1831). Type locality, Sitka. 



Near Dalton I^anding, August 15 (No. 123), growing anuing shaded rocks in a 

 canyon leading from tbe St. Elias riinge. This plant so closely reseuibles a small 

 saxifrage, Saxifra<ia niidicanlis for example, tbat a- critical look at tiie corolla is 

 necessary to distinguish it. K\en tbo thickened l)ases of llu; i)etiules and tbe two 

 divergent carpels of the uiature iVuit precisely simulate those of certain saxifrages, 

 yet they have the nio.st widely different genetic relation.
