Asa Gray states calyx viseons. the lolies little longer than the tube; in all the 

 specimens collected the calycine lobes are twice as long as the tube. 



The plant does not only occur on the summit of Kauai as for example on 

 j\[t. AVaialeale, but also on the outskirts of the bogs in the forests at a lower 

 elevation. When found in the latter locality the stems are stouter and taller; 

 they then grow usually on the trunks of moss-covered trees. 



Specimens were observed in the forests on the Ixirder of Kauluwehi swamp at 

 an elevation of 4000 feet. Lobelia Kauaciisif; is a very handsome species worthy 

 of cultivation, as are the other species of Lol)elia occurring in Hawaii. 



When growing on the extensive bogs at the sunniiit of Kauai (Mt. Waialeale, 

 5200 feet elevation) it is associated with Felca Waialcalae, Panicum monticoUi, 

 Panicuni isarhn(ildes, Oreohuhis fiircattis. Saiiiciila, Acntnia e.rigua. Viola Kaua- 

 cnsis. I) II ha 1(1 ill Waialealac and others. 



The type of Asa Gray's Lobelia Gaudichaudii var. Kauaensis in the Gray 

 Herbarium ccmsi.sts of a few fragments of tlowers, and the outline drawing- of a 

 leaf, which must have been made after a leaf taken from a .sterile specimen ; 

 the drawing of the leaf is exceptionally large and leaves of that size occur only 

 on plants which have not as yet reached the flowering stage. When the plants 

 begin to flower the leaves drop oft" gradually. 



Heller's specimen is in excellent condition, and is identical with the glabrous 

 specimens collected by the writer on 'SIX. Waialeale. Kauai.

(Plates 43, 61.) 



stem (i-10 thii high, covered with leaf-scars as in the typical form of the 

 species, inflorescence branching candelabra-like, or a single spike about 55 cm 

 long and 1 cm or more in diameter, villous-hairy throughout, light green in 

 color; lower leaves oblong, sessile with a broad l)ase, 9-14 cm long, 3.5 cm wide, 

 with thick prominent midrib and obscure venation, liluntly acute at the apex, 

 glabrous below with the exception of the midrib and the entire margin, pubescent 

 above, upper leaves gradually reduced to foliaceous, broadly ovate bracts; 

 raceme more densely flowered than in the typical form, villous, the flowers ar- 

 ranged along the upper third of the spike, pedicels and calycine tube villous 

 with whitish gray hairs, the calycine lobes green, but ciliate at the margin; 

 corolla shorter than in the typical form but broader, whitish green, the veiiLs 

 Very indistinct, oifly visilile in the buds, slightly pur|)lish tinged.

A much stouter plant than the typical form of the species, difl:ering in the 

 broad, fleshy, oblong leaves, and broad, ovate bracts. The whole aspect of the 

 plant is dift'erent ; the typical form is glabrous and lias dark purple, slender, 

 glabrous racemes, while the racemes in the variety, which is almost worthy of 

 specific rank, are thick, stout, bright green and villous throughout. The villosity 

 and compact character of the plant are not due to location, for both the typical 

 form and the variety grow side by side in the open bog of ]\It. Waialeale on the 

 island of Kauai, at an elevation of 5000 feet, in company with Compositae. 

 Drosera longifolia L., several species of Plaiifago, Paniciiin monficola Hook, f., 

 P. isachnoidca Munro, P imbricaium Hillbrd. and Onoboliis fiirvafiis H. ]\lann.
