190 LEAFLETS. 



Probably descended from the subalpine M. implexus of northern 

 California, but with no such underground growth, and good 

 characters of its own. 



M. PAificuLATUS. Stems stout and somewhat fistulous, 1 to 

 2 feet high, glabrous, remotely leafy, small plants simply race- 

 mose at summit, the larger in a manner paniculate, each axil 

 bearing a raceme instead of the usual }^eduncles ; root not seen : 

 lowest leaves 3 or 4 inches long, peduntles and blade about equal 

 as to length, the latter oval, obtuse, doubly dentate: pedicels 

 and calyx as well as bracts minutely villous : corolla yellow, li 

 inches long, with short tube and broad limb.

 son. 



M. PKioisroPHTLLiJS. Stems simple, 8 or 10 inches high from 

 a short horizontal base or rootstock, not stoloniferous, probably 

 only annual or biennial, densely leafy at base with somewhat 

 rhombic-ovate or deltoid-ovate obtuse leaves an inch long or 

 more, on very short winged petioles, the cauline smaller and 

 remote, of obovate outline and sessile, all definitely and not very 

 finely pubescent and rather closely subserrate-dentate ; floral 

 bracts ovate, cuspidate, not more pubescent than the proper 

 foliage, calyx rather less so : corolla I inch long, wholly yellow ; 

 the few flowers all long-pedicelled.

A Further Study of Chaptalia. 



The reference is to pages 154 to 158 preceding, an enquiry into 

 the tenability of Chaptalia as the name for a certain genus 

 of American Mutisiace^'. What led to that study were the 

 C. alsophilfl and confinis of p. 158. The investigation of these 

 Civo v\as not made without examination and comparison of a 

 large collection of herbarium material in the National Museum 



^ I use this name purposely as that of a Natural Family ; one clearly distinct 

 from all other so-called Composltae There is, in my view no true relation, and 

 nothing but the merest analogy between these plants and either asters or sun- 

 flowers.
