Notes on the Flora of Arizona 



Lyman Benson 



In this article the follow^ing topics are discussed : ( 1 ) A New 

 Haplophyton from the Southwest ; (2) Triodia eragrostoides in 

 Arizona; (3) The California Poppy in Arizona. 



1. A New Haplophyton from the Southwest 



Dr. D. M. Crooks, head of the division of drug and related 

 plants of the Bureau of Plant Industry, Washington, D. C, pointed 

 out to the writer a difference in appearance of the Arizona plants 

 of Haplophyton cunicidinn from figures of the same species grown 

 in Mexico. Investigation of the characters of specimens obtained 

 from the United States National Herbarium and in the University 

 of Arizona Herbarium has resulted in the following segregation : 



HAPLOPHYTON CIMICIDUM A. DC. var. Grooksii L. 

 Benson, var. nov. Leaves lanceolate, 15-27 or rarely 32 mm. long, 

 4—8 or 10 mm. broad; seeds 6-7.5 mm. long, somewhat grooved 

 and ridged, commonly with part of the surface with broad papillae 

 resembling pebble-grained leather. Foliis lanceolatis, 15-27 mm. 

 rariter 32 mm. longis, 4-8 mm. rariter 10 mm. latis; seminis 6-7.5 

 mm. longis, striatis vel partim papillatis. Southeastern Arizona to 

 Western Texas ; southward into Northern Mexico. Type collec- 

 tion: "Prison Road," Santa Catalina Mountains, Pima County, 

 Arizona, D. M. Crooks & Robert A. Darrow, Dec. 27, 1939. Type 

 mounted on three sheets in the Herbarium of the University of 

 Arizona. 



The corresponding characters of typical Haplophyton cimicidum 

 are as follows : Leaves ovate-attenuate, 35-45 mm. long, 14—22 mm. 

 broad; seeds 8-10 mm. long, deeply grooved and ridged. The 

 species is common in southern and central Mexico, and it occurs 

 as far northward and westward as Guaymas, Sonora {Palmer in
