Delissoa undulata Gaud. Bot. Voy. Uranie, 457, pi. 78. 1830. 



As stated by Dr. Gray, in Proc. Am. Acad. 5: 148, D. subcor- 

 data seems to be nothing but a form of this species, for, as he 

 remarks, " leaves with the base subcordate, obtuse, or acute, 

 being found on the same stem." Scattered plants may be 

 found on the grassy slopes west of the Hanapepe river, Kauai, 

 at elevations of about 2000 feet. On an individual plant may 

 be found young leaves which answer to the description of D. 

 undulata, while the old leaves agree with description of D. sub- 

 cordata. The blades of the mature leaves are often seven 

 inches long, with petioles six inches long. The slender, green- 

 ish corollas are curved.

LOBELIA L. Sp. PL 929. 1753. 



Lobelia kauaensis (A. Gray) 



Lobelia gaudichaudii var. Kauaensis A, Gray, Proc. Am. Acad. 

 5: 150. 1862. 



Had Dr. Gray seen these two plants in the living state, he 

 certainly would not have considered the one a mere form of the 

 other, worthy of varietal rank only. My specimens were col- 

 lected in the bog at the head of the Wahiawa river. The trunk, 

 three or four inches in diameter, is covered with leaf scars, and 

 rises to a height of five or six feet, when it sends out five can- 

 delabra-like branches of nearly two feet in length. The upper 

 half of these branches is covered with very large, curved flow- 

 ers, two inches or more in length, usually of a pale purple or 

 pink, with deep purple stripes, and on pedicels of an inch in 

 length. The calyx is slightly over a half inch in length, the 

 lobes oblong, blunt, longer than the tube. The oblong-lance- 

 olate leaves are a foot and more in length, sessile, with a, broad 

 base, acute. Those on the branches are of the same shape, 

 but gradually decrease in size, until just below the flowers they 

 are only an inch or two long.

I saw L. gaudichaudii on the summit of Konahuanui, but it 

 was just out of flower. It is a species of very different growth. 

 The stems are simple, as a rule, and only an inch or two in di- 

 ameter. The original description of it in DC. Prodr. 7 : 384, 

 calls for " planta 3 pedalis medulla farcta. Folia 3-4 poll, 

 longa, 6-12 lin. lata, erectiuscula." The corolla is described as 

 only three times louger than the calyx.
