variously shaped terminal clusters, sometimes corymbiform ; invo-

44, Sidalcea À Gray.’*—Perianth nearly of Malva ; calyx 5-fid. 
Stamens , apex of column double ; exterior in 5 phalanges, apex 
4—~x -antheriferous ; interior divided into » filaments. Germen of 
Malva ; cells: 5-10; style branches same in number, filiform, in- 
wardly longitudinally stigmatiferous. Mature carpels membranous, 
erostrate, indehiscent, separating from short axis. Seed ascendent 
(of Malva).—A herb; habit of Aalva ; leaves sometimes lobed or 
partite ; flowers ecalyculate,’ in spikes or terminal racemes ; pedicels 
0 or short (Worth Western America’). 
45. Napæa L.'—Flowers dicecious (nearly of Aalva) calyx 5-

dehiscent or sub-2-valved, separating finally from short axis; seed 
ascending (of JJalva).—Loftly perennial herbs, leaves alternate, 
more or less deeply partite; flowers’ ecalyculate, in false fasciculate-
