 great part of the summer, and with seed-pods in the autumn. Readily 

 distinguished from H. Ka\midnum, by the leaves, bracts, and sepals being 

 much smoother and shining.

Other Species of Yiypericum. The only truly hardy shrubby species of 

 /Hypericum are, H. elatum, H. hircinum, H. calycinum, H. KalmwH?, and 

 H. prolificum. The other hardy species are of such low growth, that they 

 may be considered, for all practical purposes, as herbaceous plants. H. 

 ncpalensc Royle appeared to be hardy in the Hort. Soc. Garden, but it was 

 destroyed by the winter of 1837-8. H. adpressum Bartr., H. Yosmarinifdliiim 

 Lam., H. gnlioides Lam., H. fasciciddtum Lam., and some other shrubby or 

 frutescent species, are described by Torrey and Gray, but we are not aware of 

 their having been yet introduced.
