Rhododendron L. 
viscosum (L.) Torr. Clammy Azalea. White Swamp Honey- 
suckle. Belchertown, etc. Rather rare and local. 
More common near the coast. 
viscosum (L.) Torr. var. glauwcum (Michx.) Gray. Springfield, 
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. 
canadense (L.) BSP. Rhodora. 
Kalmia L. Laurel. 
latifolia L. Mountain Laurel. Spoon-wood. 
latifolia L. forma polypetala Nicholson. [See Alfred Rehder 
in Rhodora, Vol. XII, p.1.] This interesting form 
of Kalmia was discovered by Miss M. Bryant at 
South Deerfield, and described by Asa Gray in the 
Am. Nat., Vol. IV, p. 373; 1871. In this form the 
corolla is completely divided into linear or liliform 
divisions. One of these forms is in the Arnold 
Arboretum, and Prof. C.S. Sargent has figured 
and described it in Garden and Forest, Vol. Il, 
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, rgro, a large 
clump of the same was discovered at Mt. Toby.
