Heller : PLANTS OF THE HAWAIIAN ISLANDS. 801 



Cyperus umbellatus (L.) Benth. PL Hongkong. 386. 1861. 



Kyllingia umbellata L. Suppl. 105. 1781. 



This plant was collected on a grassy ridge back of Waimea, 

 Kauai, at an elevation of 2500 feet. It was seen in only this one 

 place. 



October 1 (2851); original locality, "inlndiis." 



ELEOCHARIS R. Br. Prodr. PL Nov. Holl. 1: 224. 1810. 

 Eleocharis ovata (Roth.) R. & S. Syst. 2: 152. 1817. 



Scirpus ovatus Roth. Catal. 1:5. 1797. 

 Scirpus obtusus Willd. Eaum. 1:76. 1809. 

 Eleocharis obtusa Sciiultes, Mant. 2:89. 1824. 



Collected at the foot of Hanapepe falls, on the island of Kauai. 

 It does not seem to differ materially from the widely distributed 

 American plant. 



July 2 (2488). 



FIMBRISTYLIS Vahl. Enum. 2 : 285. 1806. 



Fi mbristy lis poly morpha Boeckl. Linnaea, 37:14. 1871. 



Collected in Pauoa, Oahu (2385), and along the Hanapepe 

 river, Kauai (2475). Of the forty synonyms of Boeckler, it is 

 a hard matter to decide which is the proper name for the 

 Hawaiian plant. The coining of a new specific name by Boeck- 

 ler was certainly not admissible, even if there was sufficient 

 ground for uniting all of the species which he cites. It is im- 

 possible for me to obtain the proper name for this plant, hence 

 the use of the meaningless term Frimbristylis polymorpha. 



Fimbristylis uinbellato-capitata Steud. ? 



Specimens collected at Waikiki, Oahu, within the race track 

 enclosure, where there is a pool of brackish water, seem to be- 

 long to the plant which Hillebrand designated as a variety 

 u mbellato capitata of F. cymosa, which is " F. umbellate- capitata 

 of Mann, Euum. no. 518, but probably not of Steud." Mann 

 does not state where his specimens were collected. Hillebrand 

 records it from nearly all of the islands, and states that it is 

 found "in higher and exposed localities, and more frequent 

 than the first form" {cymosa). Waikiki, where it was collected 

 by me, is practically at sea level. 



March 20 (1958).
