P. MONOPHYLLA AND CEMBROIDES 31 
P. Monopuytta,. the one-in-a-cluster representa- 
tive, is a very slow-growing tree, and only occasionally 
seen in botanical gardens. Though it is rumoured 
that attempts to grow them—and we may include 
in this remark the Edulis and Cembroides—were 
made many years ago, evidences of these efforts are 
apparently not very forthcoming. A few have, we 
believe, been planted of late years by collectors of 
the ‘‘unordinary.” As the tree only seems to 
increase at a rate of about 3} in. per annum, it must 
be presumed that those who plant, plant for a far- 
distant-off posterity. Yet even this tree, with all its 
sloth of habit, does not bear away the palm, under 
Grand National Donkey Race rules (when the first 
is last, and the last first), in any competition of this 
description among its kindred companions, since the 
P. Eputis grows at a still slower pace. It and the 
P. PARRYANA, or QUADRIFOLIA (as it seems better 
known in America), the representative of the four- 
in-a-cluster member of the family, are more or less 
non-existent in the British Isles, though Veitch in his 
manual of Conifers suggests hopeful possibilities for 
the latter in a Cornish or Devon climate. I cannot 
hold out encouraging hopes to any in quest of their 
seed. So far it is the only one mentioned in the 
fifty-two species of Pines by Elwes and Henry that 
I have failed to add a specimen of to my cone col- 
lection.

member of the group. 
After diligent search, quite respectably grown 
specimens of this tree have been found growing in 
several places in Great Britain. Though not of much 
account evidently here, or highly recommended by 
the faculty, these trees bear in the central scales of 
their cones highly prized delicacies of an edible
