CEnothera fruticosa Lin. var. phyllopus Hooker. 



This is a form in which there is no distinction between stem and 

 peduncle ; the floral leaves are like those of the stem^ giving to the flowers 

 the appearance of being solitary and axillary. Freely branched. Detroit, 

 No. 1261, June 30, 1916. Occasional and perhaps an escape from 

 cultivation. 



CALCARATACE^. 



Viola papilionacea Pursh. var. alba (T. & G.), N. comb. 



Viola cucullata Ait. var. alba T. & G. Fl. N. Amer. I. 137, 1838. 

 Smooth; flowers white. Frequent in places. Near Rochester. No. 

 3628, May 10, 1914, and near Rockwood, No. 4.144, May 21, 1916. 



Viola ros-Trata Ait. var. phelpsiae (Fernald), N. comb. 



Violata rostrata Ait. forma Phelpsiae Fernald, Rhodora XVII, 180, 



1915. 

 Flowers white. Near Rockwood. No. 4146, May 21, 1916. 



Viola pedatifida, Don. 



I have seen living plants of a violet collected by Mr. E. W. Mason of 

 Lapeer, which had palmately, many-divided leaves, the divisions of which 

 were very long and narrowly linear or filiform. It probably belongs 

 here, where it may be placed until further study will determine its 

 proper disposition. This species has not before been reported from 

 Michigan. 



MONOTROPACE^. 



Pyrola asarifolia Mx. var. incarnata (Fisch.) Fernald. 



Leaves orbicular to ovate, rounded, truncate or subcordate at base, dull, 

 smaller than in the specific type which are of a different form also. Com- 

 mon in swamps at Marl Lake, No. 4184, June 11, 1916, and Nos. 4218 

 and 4219, June 18, 1916, from near Pontiac. 



Pyrola asarifolia Mx. var. uliginosa (Torr. et Gray), N. Comb. 



Pyrola uliginosa Torr. et Gray; Torr. Fl. N. Y. I, 453, pi. 69, 1843. 



Leaves sub-orbicular to obovate, narrowed to an acute base; smaller 

 than in the preceding variety; not common. Swamps at Marl Lake, No. 

 4185, July 9, 1916. 



POLEMONIACE^. 



GiLiA RUBRA (Lin.) Heller. 



Near Farmington, No. 4357, August 12, 1916. Probably an escape 

 from cultivation but seems to be well established. First discovered, I 

 believe, by Mr. Gladewitz.
