912 MINNESOTA BOTANICAL STUDIES. 



Lobelia tortuosa n. sp. (Plate LXVll). 



Woody; stems clustered from a thick mass of roots, the older 

 ones almost an inch in diameter at the base, gnarled and twisted, 

 the young flowering and leaf-bearing ends ascending and spar- 

 ingly branching, closely studded with leaf scars; leaves nar- 

 rowly lanceolate-oblong, slightly cyathiform, acuminate at the 

 apex, tapering at the base into a short winged petio'le, six 

 inches in length, three-fourths of an inch wide, light green and 

 somewhat pubescent above, pale and densely soft pubescent be- 

 neath, with prominent midveins; flowering branch angled; ped- 

 icels a half inch in length, horizontal for half their length, 

 then twisted and curved upward, each subtended by a subulate 

 bract, tomentose; calyx shallow cup- shaped, truncate, shortly 

 pubescent, the lobes linear, almost as long as the tube; corolla 

 an inch and a half in length, garnet colored, somewhat con- 

 tracted near the middle, pubescent, lobes revolute; stamens 

 glabrous, or occasionally with a few scattered hairs; lower an- 

 thers tufted at the ends with white hairs; style with a pubes- 

 cent ring at the base of the stigma. 



The type is No. 2443, collected on perpendicular cliffs along 

 the Hanapepe river, Kauai. The thick, knotted mass of roots 

 protrude Irom crevices of the rocks, and from them spring the 

 at first declined and twisted, finally ascending, sparingly 

 branched stems. Its nearest relative seems to be L. neriifolia 

 A. Gray, from east Maui. Mr. Fernald has compared the two, 

 and finds them quite distinct. 



ROLLANDIA Gaud. Bot. Voy. Uranie, 458, pi. 74. 1830. 



Rollandia lanceolata Gaud. Bot. Voy. Uranie, 458, pi. 7b. 

 1830. 



There seems to be some doubt as to whether R. lanceolata is 

 the proper name since Dr. Gray says it is quoted as B. montana 

 on the plate. Hillebrand has recorded a number of forms and 

 varieties. To one of these belong my specimens, collected on 

 the lower slopes of Konahuanui. The stems are simple, smooth, 

 nearly an inch in diameter, inclined to be decumbent. The 

 leaves are often two feet long, acute at each end. The flowers 

 are red-purple, over two inches in length, curved. Rollandia 

 is a genus which is found only on the island of Oahu.
