229. Argtroxiphium macrocephalum, Gray, in Proceed. Amer. 

 Acad. 2, p. 160, &. 5, p. 137. — The tuft of linear silvery-pubescent 

 leaves from the shoft and thick stem is sometimes as much as four feet 

 in diameter, and the compound branching panicle arising from their 

 midst, six or eight feet high, bears innumerable heads of flowers, which 

 are yellow in the disk and purple in the ray. (M. & B.) 



230. WiLKESiA GYMXOXiPHiUM, Gray, 1. c. 5, p. 136. — This looks 

 much like an ArgyroxipMum raised upon a stem 6 or 8 feet high. The 

 leaves are Yucca-like, whorled, and their connate cup-like bases over- 

 lapping one another from below upwards. The compound panicle is 

 one to three feet long, bearing small yellow heads, about half an inch in 

 diameter, on very slender peduncles and pedicels. — Only found on the 

 dry southwestern slopes of the mountain of Kauai. (M. & B. 535.)
