IDENTIFYING PLANTS 143 
This one evidently belongs to Sub-class Calyciflore. 
We scan the Natural Orders of this Sub-class until 
we reach Onagracee (‘“‘Johns,” p. 92). Now we 
have determined the Order, we ought not to have 
much difficulty in settling the species, for there are 
but five genera, and the greatest number of species 
are included in the genus Hpilobium. There is no 
Sub-order in this case. Yes, our plant is an 
Epilobium ; it answers splendidly to the require- 
ments of that genus; and the second species that 
is described is the one we are looking for. The 
plant we hold in our hands is H'pilobium hirsutum, 
the Great Hairy Willow Herb, or Codlins-and- 
Cream (see photograph on Plate 20, a). 
The Buck Bean (Menyanthes trifoliata), illustrated 
on Plate 20, b, is another of the plants I have 
gathered. It represents the Sub-class Corolliflors 
and the Natural Order Gentianacese. Did you ever 
see a more exquisite flower? Its ternate leaves 
are somewhat like those of a Broad Bean, but its 
flowers, to my mind, are the very acme of beauty. 
See the delicate white fringe on the petals! What, 
indeed, could be lovelier! But you should have seen 
the big patch of these flowers on the marshy ground 
from whence I brought this specimen : it would have 
given you some idea of how Nature beautifies 
apparently waste places, and makes them sweet. 
The Buck Bean is decidedly a flower to hunt for, 
and once you make acquaintance with it in its 
natural haunts, you are not likely to forget it. 
Some people call this flower the Bog Bean, and it is 
a good variation of its name, for it grows in and 
beautifies boggy ground.
