who are assisted by Noctuw. On this account its 
sweet perfume is only given off at night. The 
flower being so widely opened, honey would in the 
ordinary way be accessible to all callers, but to save 
it for the long-tongued ones who can cling to stamens 
and pistil and dust themselves with pollen what time 
they are drinking, an ingenious plan is adopted. The 
honey lies along the centre of the basal half of each 
petal, in a deep groove which is walled in by thick, 
arching borders fringed with stiff hairs, which pre- 
clude admission to any insect’s tongue unless it be 
inserted at the open end. The accompanying figure 
(after Miller) will make this plain. After the moth 
has clung to the stamens in alighting, it climbs up to 
the tips of the petals, and feeling the way between 
the little pointed warts studding the surface of the 
petal, finds the entrance to the nectary (c). 
If we were to dig up the bulb of this Martagon 
Lily—but I do not suggest that any reader who 
comes across its sole British station should do so, for 
a White Lily or Tiger Lily from the garden will do 
as well—we should get the best insight into the 
true character of these bulbs. In all species of the 
genus Liliwm the bulbs consist of a large number of 
fleshy scales overlapping each other. Now, the very 
form of these will convince the investigator that 
they aremerely undeveloped leaves, which have been 
enormously thickened to serve as storehouses for the 
starchy wealth of the plant. Any one of those scales 
separated from the mass will develop into one or 
more tiny bulbs. Sometimes such miniature bulbs 
form at the base of the scale, sometimes around the 
edge.
