 Rhododendron L. 



viscosum (L.) Torr. Clammy Azalea. White Swamp Honey-

 More common near the coast.

 L. Andrews. 



nudiflorum (L.) Torr. Purple Azalea. Pinxter Flower. 



canescens (Michx.) G. Don. This species seems to be more com- 

 mon than the preceding in the Conn. Valley. Ac- 

 cording to our observations" a mark of distinction 

 between the two is the simultaneous appearance of 

 flowers and leaves in R. canescens.

latifolia L. forma polypetala Nicholson. [See Alfred Rehder

 of Kalmia was discovered by Miss M. Bryant at 

 South Deerfield, and described by Asa Gray in the 

 Am. Nat., Vol. IV, p. 373 ; 187 r. In this form the 

 corolla is completely divided into linear or hhform 

 divisions. One of these forms is in the Arnold 

 Arboretum, and Prof. C. S. Sargent has figured 

 and described it in Garden a?id Forest, Yo\. II, 

 pp. 452-453. The writer discovered a similar form 

 in Leverett near a roadside, in 1907. (See Rho- 

 dora, Vol. II, p. 199.) And in June, 1910, a large 

 clump of the same was discovered at Mt. Toby.
