three-deft spreading lip. The only mature capsule seen belonging to 

 an emersed flower is hardly over three lines long and clavate-oblong. 

 Immature submersed capsules are of double this length and fusiform, 

 their setaceous calyx-lobes commonly three lines long. The ovary is 

 Strictly one-celled from the first. The submersed plant lias somewhat 

 the aspect of Naias Jiexilis or a narrow-leaved Anacharis ; the stems 

 a foot long ; the leaves an inch or two long, and a third or a fourth of 

 a line wide. These are alternate, tending occasionally to opposite 

 and verticillate, generally quite entire, but sometimes with one or two 

 lateral teeth. The emersed leaves seen are only two lines long, and 

 are not unlike those of Doumingia ptdchella. Possibly this new plant 

 might be brought under that genus, but not with propriety. Besides 

 the sessile long-linear ovary, the uniseto-e anthers, and the great in- 

 equality of the two lips of the corolla, the tube in that genus is more 

 deeply cleft laterally than between the two small petals. Our plant 

 must accordingly be received as a new generic type, allied to L>/sipo- 

 mia, IIBK. (Lysipoma, A. DC). Doumingia, and somewhat to Lnuren- 

 tia. but not referable to any of them. It is dedicated to the discov- 

 erers, who are assiduous collectors and acute observers, and who have 

 already much increased our knowledge of the botany of Oregon.

 Cascade Mountains. S. Oregon, and now (1878) collected by V. 

 Rattan, in Fir (^Douglas Spruce") forests, on the north fork of Mad 

 River, in Humboldt Co.. California, in fine flowering state, with 

 corymbiform-glomerate inflorescence on a very short stem, of only an 

 inch or two in height. The lower scales are apparently rather broader 

 than in Newberry's plant. The specimen collected by the late George 

 Gibbs apparently belongs to the following specie-.
