Should also cliech Lamoureauxpaper for his 
no doubt better opionion on -whether man- 
introduced or not. Forget it- checked for you 
Comment 
Native^ extirpated. Reintrodution attempts 
apparently unsuccessful! 
Apparently introduced by military in 1960 *s 
Probably now well established. 
Introduced by guano workers 
Rative^, not present 1923? reestablished itself 
from either seeds or materials planted in 1923 
Surely an introduction by man, last seen in 
1896. 
Last found 1903 ? 1923 planting failed. 
Race is endemic to Laysan 
Probally result of introduction in I923 
Endemic species or same as that on Rihoa 
Onions introduced by man, found growing, were 
extirpated by man. 
=S. cuneat um var laysanicum of Lamoureaux who 
listed it as an endemic race or variety. 
Recently has been reduced in synonymy. 
Disappeared between 1903 - 19 H* Several 
reintroductions, with species possibly 
re-establishing on Mar. 69. 
Reintroductions failed. Some of the^native" 
species (which I have assessed from Lamoureaux's 
account from those occurring on both Leewards 
and mamn Hawaiians) conceivably were introductions 
from the main islands. Your guess is as good as 
mine. 
Last reported I903 ’ 
First collected 1959 ? natural or man introduction? 
Lamoureaux thinks MI 
Reintroductions failed
