Brickellia squamulosa, Gray, Proc. Am. Acad., xv. 30, comes 

 into our flora, being found by Mr. Greene to occur abundantly in New 

 Mexico. It is woody only at the base, sending up long and simple 

 stems which bear narrowly linear leaves, 2 or 3 inches long and less 

 than two lines wide the first year ; they flower the next year, when 

 they bear only squamiform and minute leaves or bracts. 



Garbicria fkuticosa, Gray, in Proc. Acad. Philad., Nov. 1879, 

 379. Having followed Bentham and Hooker in the restoration of 

 Cassini's genus IVilisia, I found Nuttall's Liatris fruticosa still more 

 worthy of generic distinction. But, in taking up Nuttall's subgeneric 

 name of Leptocllaium (in Proc. Am. Acad. xv. 48) I overlooked the 

 patent fact that Gardner had used that name, somewhat illegitimately, 

 for an allied Brazilian genus. Whereupon, as the above reference 

 shows, I promptly took the opportunity of dedicating our genus, to 

 the rediscoverer of the plant, Dr. A. P. Garber, of Columbia, Penn- 

 sylvania, a most devoted and acute botanist, who has done more for 

 the development of the botany of subtropical Florida of late than any 

 one, except Mr. A. H. Curtiss, who is still in the field. 



APLOPAPPUS. The primary sections of this extended genus, as 

 here accepted, are Priojiopsis, Aplopappus proper (which is made to 

 include £riocarpum, Nutt., Pijrrocoina, Hook., Himiopnppiis^ Nutt., and 

 Sideranlhus, Nutt.), Isopappus, Steiiotus, Ericamcria, and Macronema. 



Aplopai'pus integkifolius, T. C. Porter, is taken up from an 

 unpublished name of a plant collected in Wyoming by J. M. Coulter 

 and also by Burke, a species between A. lanceolatas or paniculatus 

 and A. iniijiurus. A. Parryi, whicli inclines on the one hand toward 

 Solidaqo, especially in a reduced form (var. depauperalns), is in- 

 cluded in the Stenotus section. A. nanus takes in A. cervinus of 

 Watson as a variety, and the following new species are brought to- 

 gether into a subsection of the Ericameria section, which is transitional 

 between that and the section Macronema. 



Aplopappus Watsoni. Viscidulo-pubescens, spithama^us ; ramis 

 fastigiatis subherbaceis e basi lignosa ; foliis lanceolatis sen angusto- 

 spathulatis oblongisve mucronato-acuminulatis membranaceis (vix pol- 

 licem longis) ; capitulis pauciusculis subglomeratis ; bracteis involucri 

 lanceolato-linearibus acutis vel acuminatis plerisque tenuiter charta- 

 ceis vel paucis herbaoeis, omnibus erectis ; ligulis 4-8 ; floribus disci 

 vix numerosioribus ; appendicibus styli ramorura setaceo-liliformibus.
