these results may be noted abnormal development, without asymmetry or 

 irregularity, in the enlargement of parts, particularly the lengthening of 

 scapes, of petioles, of peduncles, of claws. 



In the accompanying figure is outlined a plant wholly normal except 

 for the long petioles and peduncle, and the coloration of the petals, which 

 were partly green and white. This includes two kinds of abnormality. 



It is to be regretted that at the various times these abnormal plants 

 were noted or collected little if any attention was paid to the exact condi- 

 tions under which they were growing. Accordingly it is impossible 

 definitely to state which results obtain from any set of conditions, as 

 interesting as such facts would be. Reparative abnormalities have been 

 noted by the Macouns, father and son, in Trillium undidatuni and cermium, 

 and in Trillium sessile in this paper. Physiological abnormalities have 

 been noted by Mr. J. M. Macoun in Trillitun grandiflortan (Canadian 

 Rec. Sci., Oct., 1897, 476, 477) ; and by Mr. H. W. Britcher in the same 

 species (Maine Agric. Exper. Sta. Bull. 86, Nov., 1902). Two specimens 

 collected by Mr. G. B. Grant, at Moose Head Lake, Maine, in August 

 1898, have the simple leaves long-petioled from the rootstock, probably 

 developed as suggested by Mr. Holm for Trillium sessile. Mr. Grant's 

 specimens probably are Trilli^cm grandi/lorum. He writes that one 

 botanist has called them " fall leaves," thereby suggesting a likeness to 

 the putty-root and Tipularia. However in these the only foliage leaves 

 are autumnal, while in Trilliurn the usual whorled leaves are foliage leaves. 

 To settle this point, careful observations should be made on Trillium 

 beds during the coming season between May and October.

EARLY BLOOMING OF SPRING FLOWERS IN THE VICINITY OF 



WASHINGTON. 



Prof. C. A. Wheeler, of the U. S. Dept. of Agriculture, who for 

 many years has kept a record of the time of blooming of plants, reports 

 that for many species the time of blooming in a given locality may vary 

 through a period of about thirty days. In the vicinity of Washington he 

 has this year observ^ed Berberis japonica in bloom since Christmas ; Chim- 

 onanthus fragrans (^Caly canthus praecox JJinn.^ since Februar>^ 1 ; Almis 

 Japonica February 10, shedding its catkins February 14; Acer saccharinum, 

 Forsythia viridissima and Forsythia suspensa February 13 (the last in shel- 

 tered places). At Glen Echo Miss Sipe found Hepatica triloba blooming 

 profusely February 8, W. E. S.
