REPORT OF THE STATE BOTANIST FOR I92I 53 



Opuntia Opuntia (L.) Coulter 

 On ledges of rock about 5 miles south of Saugerties. House 

 8419, July 23, 1 92 1. 



Viola palmata x sororia hyb. nov. 



Early leaves broadly ovate to reniform, entire or with some of 

 the blades slightly lobed, somewhat pubescent above, glabrous 

 beneath and on the petioles; later leaves softly and rather densely 

 pubescent on the petioles and lower leaf surfaces, the blades less 

 pubescent above, variously 3 to 7 lobed or nearly entire ; flowers 

 abundant but soon withering without developing fruit ; capsules 

 all from cleistogamous flowers on short, horizontal or deflexed and 

 buried peduncles. 



Saugerties, Ulster county, C. H. Peck, May 10, 1904. Type. Also 

 collected at Van Cortlandt Park, New York City. House. 



Aster violaris Burgess 

 Rocky woodlands near Cragsmoor. House 8579, August 20, [921. 



Aster Claytoni Burgess 



Woods near Napanoch. House 8366, August 21, 1921. 



In these specimens the leaves are thin, and with the white rays 

 and suJbumbelliform clusters of the heads of the inflorescence matches 

 well the description and plate by Burgess. It differs, however, in 

 that the branches of the inflorescence and the bracts are densely 

 glandular-canescent, the outer shorter bracts conspicuously green, 

 inner longer ones with green midveins and green tips, all blunt 

 or rounded and conspicuously webby-ciliated on the margins. The 

 disk is pale or whitish, turning to slightly crimson with age. These 

 characters do not accord well with the complete description of A . 

 Claytoni, and the same lack of complete agreement of characters 

 is to he. noted in regard to many other recently collected specimens 

 of Biotian asters with the descriptions by Burgess. It leads to the 

 conclusion that following the lines marked out by Burgess an indefi- 

 nitely larger number of so-called species might be established with 

 as little satisfaction from a systematic point of view as prevails in 

 the treatment of New York Crataegus by Sargent.
