PRELIMINARY LIST OF HEPATICS COLLECTED IN WORCESTER, 
riASSACHUSETTS. 
Heleiv E. Greenwood, 
The Hepatics listed below have been collected by the writer within the 
limits of Worcester, Massachusetts, at various times within the last year 
and a half. Doubtless other species will be found in addition to these. 
Certain kinds are found here in abundance, but conditions are not favor- 
able for a great variety of hepatics. There is a great deal of low, wet, 
swampy land in the outlying territory of the city. The hills of Worcester 
are full of springs, so that in many localities the roadsides remain very moist 
throughout the whole season, thus affording just the right conditions for 
Blasia, Anthoceros, Pellta a.nd. Riccia. 
The acreage of woodland with the accompanying brooks is fast disap- 
pearing within the city limits so that favorable situations for such forms as 
Jainesoniella, Lepidozia, Lophozia, Na^'dia, etc. are rapidly growing less. 
Thanks are due to Miss Haynes for her determination and verification 
of species and for her encouraging words.
