Lemna minor L. Sp. PL 970. 1753. 



This species, unrecorded for the Hawaiian flora, is very com- 

 mon about Honolulu, in taro ponds, and other bodies of still 

 water. At Capiolani Park, where the specimens were collect- 

 ed, it is especially plentiful.

Astelia menziesiana Smith, in Rees, Encycl. App. 34. 



Rhizome thick, creeping, covered with thin brown scales; 

 flowering stem channeled, two feet high or less, clothed through- 

 out with dense, white wool, simple and leafless up to the inflor- 

 escence; leaves closely imbricate at the base of the flowering 

 stalk, which they slightly exceed in length, linear, gradually 

 attenuate, maximum width three-fourths of an inch, clothed on 

 both faces with appressed white hairs, midvein yellowish, 

 prominent beneath, but not noticeable above, the upper side 

 marked with two prominent lateral nerves, and a number of 

 smaller intermediate ones; inflorescence paniculate, the alter- 

 nate branches two to five inches long, each subtended by a 

 sessile, ovate-lanceolate, acuminate, leafy bract, the lowest one 

 longer than its flowering branch, about equaling the inflores- 

 cence, the others successively shorter and broader, and each 

 shorter than the branch which it subtends; pedicels at right 

 angles to the peduncle, stout for the size of the flower, nearly 

 a half inch in length, densely white woolly; bractlet at the base 

 small, shorter than the pedicel; perianth segments purple, ob- 

 long, narrowed at the apex, but hardly acute, white wooly on 

 the outside, the three inner ones less so than the three outer 

 ones, and slightly narrower, all three nerved, the outer ones 

 tipped with an incurved protuberance; stamens shorter than 

 the perianth segments; stigmas small, sessile on the narrowed 

 apex of the ovary; ovary ovoid, three- celled, glabrous.
