Crotalaria longirostrata H. & A. Bot. Beechy, 285. 1841. 



This handsome species has not spread much during the past 

 thirty-five years. Hillebrand notes it as growing along "a 

 roadside in Nuuanu valley and on the Waikiki plains near Hon- 

 olulu, escaped from the Agricultural Society's garden." I have 

 seen it only at the Nuuanu station. The flowers are rather 

 large, bright orange yellow, the keel marked with red. The 

 seeds are small, blackish.

Crotalaria saltiana Andr. Bot. Rep. pi. 6^8. 1811. 

 Crotalaria striata DC. Prodr. 2:131. 1825. 



A common weed about the streets of Honolulu, in waste 

 ground, and in fields. It occurs also at an elevation of 2000 

 feet on Tantalus, growing on the edge of the woods. It has 

 evidently been in the island since 1865, as there is a specimen 

 in the Mann and Brigham collection at the Bernice Pauahi 

 Bishop Museum, under the name of G. longirostrata. The Mann 

 and Brigham plants were collected in 1865. The seeds of this 

 species are yellowish. This species and G. incana have spread 

 much more rapidly than any of the other species, as they can 

 be found almost anywhere in the neighborhood of Honolulu. 

 It is an East Indian species, not previously recorded as occur- 

 ring in the Islands.

Collected in Nuuanu valley along the roadside, aDd in open 

 lots in the northwestern part of Honolulu. It is herbaceous, 

 with stout, branching, glaucous stems. The flowers are large, 

 an inch or more in length, bright yellow. The seeds are large, 

 blue-black.

Ervtlirina mpnosperma Gaud. Bot. Voy. "Orange, 486, pi. HJf. 

 1830. 

 This, the " Wiliwili " tree of the natives, is rather a strange 

 looking object when in full bloom, although very handsome. 

 The large flowers, which grow in dense clusters on the ends of 

 the leafless branches, are either of a brick red or pale yellow
