Heller: plants of the Hawaiian islands. 917 



at the Nuuanu Pali, appears to be the same as Nuttall's plant, 

 which was probably also collected at the Pali, It is described 

 as " less than a foot high." My specimens are ten to fifteen 

 inches high, branched. The leaves are three foliolate, the lat- 

 eral divisions sessile and oblique, the terminal ones petioled 

 and larger. No. 2894, collected at the Pali, but some two or 

 three hundred feet higher, on the steep slopes, is perhaps Nut- 

 tall's Bidgns gracilis, as it answers very well to his description. 

 It is taller, and more slender, with narrower and thinner leaves, 

 but does not seem to be distinct from G. mutica. 



March to October (1988, 2894); probably from the original 

 locality.

 Bidens sandwicensis Less. Linnaea, 6: 508. 1831. 



Gray evidently confused this with G. mutica, as the two are 

 somewhat similar in appearance, especially when not seen in 

 the living state. This species, however, is much taller, three 

 to five feet high, with larger flowers. It is plentiful on Kona- 

 huanui, Oahu, at an elevation of 2500 feet, and appears to be 

 confined to the forest, while C. mutica flourishes on open, grassy 

 slopes. 



November 2 (2901); original locality, "in OWahu." 



CENTAUREA L. Sp. PI. 909. 1753. 



Centaurea melitensis L. Sp. PI. 917. 1753. 



Abundant in a grassy field at Waikiki, Oahu. An annual, 

 about two feet high, with small yellow heads. 



May 9 (2287); original locality, "in Melita." 



DUBAUTIA Gaud. Bot. Voy. Uranie, 469, pi. 84. 

 1830. 



Dubantia laevigata A. Gray, Proc. Am. Acad. 5: 135. 1862. 



Originally described from a specimen out of flower, but quite 

 distinct from D. plantaginea, which it resembles. A shrub, six 

 to eight feet high, with branching top. The bright green, 

 glossy leaves are narrowed into margined, clasping petioles. 

 The panicle, however, is pubescent, and the flowers are yellow. 

 Collected at an elevation of 3,000 feet, on the ridge west of the 

 Hanapepe river, Kauai. It is not plentiful there, and very few 

 plants were in bloom. 



July 23 (2(316); original locality, "Kauai Sandwich Islands."
