alone a fairly conspicuous guide to differentiation. 
The P. Chilina appears to be the one more habitually 
grown with us than the others. While the length 
of its leaf is 2 in. to 23 in., the length of the Nubigena, 
which grows in a few favoured places, is only from 
I to 2 in. in length, and the Macrophylla with his more 
sickle-shaped leaves, as by his name he ought, out- 
tops the two by an average measurement of something 
between 3 and 4 in. . 
The P. Totara and.Alpinus are both comparatively 
short-leaved. Not only does the P. Chilina differ 
in length from the P. Macrophylla, but in the presence 
of stomata—stomata inconspicuous it may be, but 
stomata for all that, and of which the P. Macro- 
phylla is destitute. 
The P. Chilina (sometimes wrongly called P. Andina, 
an obsolete synonym for the Prumnopitys) has leaves, 
the under-side of which are of a yellowish colour. 
The stomata are hardly visible to the naked eye, but 
under microscopic persuasion become as clear as sun 
at noonday. To amateur apprehension this under- 
surface seems to consist of a yellowish midrib, with 
two rather greener marginal bands, and between 
them some sixteen to twenty rows of minute-looking 
stomatic bands set out in wide rows. A specimen 
before me also presents without microscopic aid one 
half-baked-looking attempt at a growth of its most 
curious-looking fruit. The impression left with me 
is that of a long stalk growing out from the stem 
and terminating in a green fruit, of a dolichocephalous 
(longer than broad) shape, and to complete the 
picture, propped up with an arrangement that 
suggests a high collar on an unnaturally large-sized 
neck. This is that swollen peduncle or stalk so 
much vaunted, and what botanists term the fleshy 
receptacle. 
The P. Nubigena has a few south-westerly haunts
