umbel-bearer, but an ally of Elder and Honeysuckle. 
We cannot stay to deal with the family, but we may 
glance for a moment at Honeysuckle (Lonicera peri- 
clymenum), because its cluster of flowers also shows 
a strong inclination to become a Composite. The 
calyces with their contained ovaries are crowded 
together at the end of a branch, and on examination 
it will be found that some of the calyces are joined 
together in pairs. The corolla has been drawn 
out into a long trumpet-shape, but opens unequally, 
not with the five lobes that denote the conjoined 
petals separate, but the limb of the corolla rather 
divided into two lips, one with three or four lobes, 
the other with one or two. The process of close 
association has begun, but at present only with the 
calyces and ovaries; the corollas stand as far as 
possible apart, and are usually half full of honey. 
The stamens and pistil, which extend beyond the 
mouth of the corolla, stand well away from each 
other. Only the larger moths and the long-tongued 
bees can reach the honey, and after the first drink 
only the moths can reach down far enough; but 
short-tongued bees come for the pollen which they 
can collect from the anthers easily, and in so doing 
no doubt effect cross-fertilisation, which is otherwise 
done by the fluffy faces of the moths as they push 
between anthers and stigma. 
Now we will turn to the true Composites, and first 
glance at the simplest native form, the Hemp Agri- 
mony (Hupatorium cannabinum),a plant that grows 
to a height of four or five feet in damp coppice and 
moist hedgerow. Its large handsome ieaves are some- 
what similar in appearance to those of the Hemp
