Goinment 
Last growing in 1923 . 
Lot present in 1923 . Reestablished either 
from own seeds or Tanager Expedition 
plantings. 
Lamoureaux includes this species in the 
list that was probably introduced by man. 
In totals I have so included it here. 
Lot sure myself that it could not have 
been a natural introduction. 
Described from Laysan, gone before I9II. 
Last reported I903 
= Solanum nodiflorum of Lamoureaux 
Sowed by man, extirpated, in one instance, 
by man. 
Sicyos hispidus of Lamoureaux and before. 
Recently described by St. John. 
= Sicyos sp. of Christophersen & Caum 
and Lamoureaux, evidently. 
Recently described by St. John 
Described by St. John from specimens collected 
by Long in Sept. 1964 . (St John lists 
C.R. Long 2,370 as both the holotype of 
Sicyos semitonsus and as an example of 
Sicyos laysanensis -Presumably a typo) 
As of St. John, only known from and 
presumably endemic to Laysan. 
Probably introduced by military in early 
1960^3.
