660 PROCEEDINGS OF THE AMERICAN ACADEMY 



It was long ago remarked, in the Flora of North America, that 

 ovaries of the ray in Agarista calliopsidea DC. are ovuliferous. I 

 have lately seen, in a cultivated plant, that they are equally if not 

 more fertile than those of the disk. The specimens under cultivation 

 showed well-formed styles to the ray-flowers ; but these I find are 

 present in all the indigenous specimens I possess, although commonly 

 short or even included in the tube. Agarista DC. -and Pugiopappus 

 are therefore congeneric. As Don's Agarista in Ericacea is earlier, 

 and is to be restored, the present reinstated genus naturally takes the 

 name of Pugiopappus. The species are : — 



Pugiopappus calliopsidea. Caule 1 - 2-pedali inferne folioso ; 

 capitulo majore ; involucri exterioris squamis ovatis basi coalitis ; ligulis 

 cuneato-obovatis (semipollicaribus ad pollicarem) ; disci corollis tubo 

 piloso-annulato ; achenis radii latis ala tenui cinctis, disci margine 

 intusque longe mollissime villosis. — Agarista calliopsidea DC. 



Pugiopappus Breweri. Minor ; foliorum lobis angustissime line- 

 aribus ; involucri exterioris squamis linearibus ; ligulis oblongo-spathu- 

 latis (semipollicaribus) ; annulo corollas disci obscuro imberbi ; ache- 

 niis radii prsecedentis, disci secus margines costamque paginal in- 

 terioris tantum longe villosis ; pappi aristis validioribns achenio 

 dimidio brevioribus. — This is the plant, collected by Professor Brewer 

 (no. 241) "on dry hills at San Buenaventura," below Santa Barbara, 

 which in Proc. Am. Acad. 5, p. 545, I wrongly referred to P. Bige- 

 lovii. It is nearer the preceding. 



Pugiopappus Bigelovii Gray, 1. c. Humilis ; foliis subradicali- 

 bus carnosulis, segmentis paucis angustissime linearibus ; capitulo in 

 pedunculo scapiformi parvulo ; involucri exterioris squamis lato-line- 

 aribus ; ligulis quadrato-oblongis ; annulo corollas disci imberbi ; 

 acheniis radii oblongis ala crassiuscula marginatis, disci (ut videtur 

 plerumque sterilibus) tenuiter ciliatis. — The style in the disk-flowers 

 is articulated above the base, and the thickish basal portion is less 

 deciduous, in all three species. In those, also, the disk-achenia, or 

 some of the central ones, are disposed to be infertile. 



Leptosyne DC, with its three genuine species and Tuckermannia 

 of Nuttall, which I long ago referred to it, has perhaps still greater 

 claim to be regarded as a good genus. L. Douglasii DC, L. Still- 

 manii Gray, and L. Newherryi Gray, differ chiefly in some details of 

 flowers and fruit ; in the latter the cup or little border which answers 

 to pappus is almost obsolete. There is no trace of it in the remark-
