though still versatile, is more rigid than in the species with 
included anthers. The sterile ends of the connectives are flat- 
tened and united, fig. 32, though they are no longer needed for 
\he same purpose as in S. gesneriaefolia, since for more than 
half the distance from their insertion to their end they are in 
close contact with the roof of the corolla, and so the elevation of 
the lower end does not tend to depress the polliniferous end in 
the least, as may be seen from fig. 30. As in S. splendens, they 
reach the floor of the corolla at some distance from the mouth, 
and their form is such that they almost completely cut off access 
to the nectar, a narrow space below their ends being the only 
passage left unclosed. 
This species is also apparently adapted to pollinators that do 
not need to settle on the flower as bees do when obtaining nectar, 
but can balance themselves before it. The small lip and the elon- 
gated tube of the corolla effectually exclude the former, if of 
large or medium size, while smaller bees are cut of by the sterile 
ends of the connectives and the contracted basal part of the 
tube. The large amount of nectar and the general form and ap- 
pearance of the flower point to birds, as before, and the obstruct- 
ing but movable connective offers no barrier to them. At the 
same time, the narrow passage beneath the connectives and the 
presence of a white stripe on each lateral lobe of the corrolla, a 
very efficient nectar mark, are very suggestive of psycophilous 
flowers, and there is reason to believe that in S. Heerii we have 
a species well . fitted to pro fit by the visits of birds and butter- 
flies, and possessing special adaptations to both. 
Westringia rosmariniformis (Australia). — Contrasted with 
the sages just described, is this curious Labiate. The corolla is 
tubular below, the two lips diverging at the mouth, the upper 
being bilobed, the lower trifid, figs. 33-34. The mouth of the 
tube is partly closed by a tuft of hair, a concentrated develop- 
ment of the pubescence found over the whole corolla. This in 
connection with hairs on the style, fig. 36, forms a guard for the 
nectar secreted by the hypogynous gland. A varying number 
of pale brown dots arranged with considerable regularity about 
the mouth of the white corolla, and especially on the lower lip, 
with a similar dot near the base of each filament are the chief nec-
