40. (iXAPHALODES, Tuumefort. Low floccose - woolly annuals,

 late flowers on a small receptacle, each enclosed in a conduplicate bract, 

 the tip of which is scarious-appendiculate; the few hermaphrodite-

 scarious. — Open ground; very common. May. 



2. a. amphibola, Greene, 1. c; Gray, Proc Am. Acad. xvii. 214 

 (1892), under Micropus. Fructiferous bracts about 10, somewhat imbri-

41. ANCISTROCARPHUS, A. Gray. Low cauescently flocculent 

 annual, erect, branched from the base, with alternate entire leaves, and 

 more or less glomerate heads. Fertile flowers 5—9, loosely disposed ou 

 a slender receptacle, their enclosing bracts cymbiform, firm except the 

 narrow hyaline tip. Sterile flowers involucrate by 5 larger bracts, these

42. ADENOCAULOX, Hooker. Perennial, with alternate dilated
