196 PROCEEDINGS OP THE AMERICAN ACADEMY, 



one of the coutineutal American species (of. L. lllacuia and L. canes- 

 cens, IIBK.), or segregated into several more or less distinct forms. 

 The indefiniteness which now prevails regarding the S. American species 

 of tlie genus is such as to render the further classification of the 

 Galapageian forms, for the present, impracticable. 



LiPPiA, Iloust. 



L. CANESCENS, HBK. Nov. Gen. & Sp. ii. 2G3 (1817). L. lanceolata, 

 Rose (1), 137, not Michx. L. nodijiora, Cham. Linnaea, vii. 213 (1832); 

 Rob. & Greenm. (1), 147; not Michx. — Charles Isl. : Lee (hb. U. S. 

 Nat. Mus.) ; Baur. Chatham Isl. : A. Agassiz (hb. U. S. Nat. Mus.) ; 

 Baur, no. 178 (hb. Gr.), a green form. Duncan Isl.: Siiochp-ass & 

 Heller, no. 709 (hb. Gr.). Hood Isl. : around a mud lake, Snodgrass 

 & Heller, no. 755 (hb. Gr.). Further distrib. S. Am. 



L. rosmarinifolia, Anderss. (1), 198, & (2), 80; Rob. & Greenm. 

 (1), 147. — Abingdon Isl.: Snodgrass & Heller, no. 827 (hb. Gr.). 

 Albemarle Isl.: in very dry places of the middle region, Andersson j 

 Elizabeth Bay, Snodgrass & Heller, no. 280 (hb. Gr.) ; eastern part, 

 Btur, no. 179 (hb. Gr.) ; Tagus Cove, not common, 150 to 460 m. alt., 

 Snodgrass & Heller, nos. 168 (hb. Gr.), 147 (hb. Gr.) ; mountain east 

 of Tagus Cove, Snodgrass & Heller, nos. 233, 251, 888, 890, & 896 (all 

 in hb. Gr.). Nos. 888, 890 & 896 show that the leaves on some branches 

 become strongly toothed. Endemic. 



Baur's nos. 181 and 182 (both in hb. Gr.) from eastern Albemarle 

 are probably branches of this species (sterile). 



L. SALiciFOLiA, Anderss. (1), 198, & (2), 80. — Charles Isl.: in 

 woods on the side of the mountain summit. Andersson (hb. Gr.). 

 Endemic.

 ticifolia, Sims, Bot. Mag. t. 1848 (1816). Verbena dichotoma, Ruiz &
