Arabis viridis Harger 



(Rhodora, 13:38. 1911) 

 Rocky woods, Glenmont. House 7872, May 24, 192 1. 

 A rather conspicuously distinct plant which seems to have passed 



unnoticed until recently, or which has been included in A . 



laevigata, from which it differs by being bright green and 



more leafy, the white flowers with conspicuous petals and the pedicels 



noticeably erect. 



Asclepias intermedia Vail 



Sandy soil west of Albany, in open fields. House 7159, July 4, 

 1920. 



The plant here recorded consisted of a single root with three 

 flowering branches. The flowers possessed the clovelike odor of 

 A. obtusifolius, which is common here, and the character 

 of the leaves also indicated that A. obtusifolius was one of 

 the parents of this hybrid. The hoods were pointed or acute as in 

 A. syriaca, but the rather darkish purple color of the flowers 

 would seem to indicate that the other parent species is A . pur- 

 purascens, which is not uncommon here, although less so than 

 A . syriaca. 



Aster persaliens Burgess 



In dense woods of mixed hardwood and hemlock, near Clarksville. 

 House 6831, October 15, 1919. 



A very distinct member of the group of species usually included 

 in Aster divaricatus L. and which should at least be 

 regarded as of varietal rank. 



Aster linariifolius L. 



This beautiful aster is very common on the sand plains west of 

 Albany, and presents numerous variations with respect to the inflores- 

 cence. The common form here as elsewhere in the State has 

 the heads of the inflorescence numerous and terminating short 

 peduncles, the peduncles provided with small appressed leaflike 

 scales. These peduncles vary in length from 4 to 10 cm and in 

 number from three or four to a stem to large congested inflorescences 

 of thirty or forty heads. Two extremes, however, merit definite 

 record, namely : 



Forma monocephalus forma nova. Stems branched near or below 

 the middle ; heads solitary and terminal on each branch, the peduncle 

 portion of which is 6 to 10 cm long, and with its reduced leaves 

 presents a marked contrast to the larger leaves below and resembles 

 somewhat in appearance single-headed forms of Aster 

 n e m o r a 1 i s . Karner, Albany county. C. H. Peck.
