place of this species, finally publishing it as ** Bzozra ?" with 
the remark : “ Perhaps a new genus ; but it agrees in many 
characteristics with Brotia discolor," e. i., with Doellingeria 
scabra Nees. That Miquel's plant was not a Biotian aster 
seems indicated by its outer involucral scales, described as 
but little shorter than the inner ones. Probably this species 
and the preceding when fully studied will be found not 
members of Aster at all.

A. corymbosus Aiton — A. divaricatus L. 
A. macrophyllus L., . . . rays white or purplish. The “ pur- 
plish” plants = A. macrophyllus L. proper; the “ white ”’ 
ones were probably in part the same in older bleaching 
condition ; and in part were rougher larger-leaved forms 
of A. Schreberi Nees. 
B. stem and leaves nearly smooth and glabrous ; heads usually 
smaller ; A. Schreberi Nees. = A. Schreberi Nees in smoother 
states ; and A. umbelliformis Bu. and perhaps other smooth- 
ish allies.

of acute. This seems the same with a rare round-bracted 
form or ally of A. macrophyllus L.; see infra.
