I. Meteorological.<br />

(a) Frost.<br />

1. Graham Officer (Proc. Roy. Soc., Tas., 1892, p. 155) referring to the Nive<br />

Plains near Lake St. Clair, speaks of them being “covered with dead and fallen trees,<br />

the result of a severe frost 50 or 60 years ago.”<br />

2. “Relative Frost Resistance of Eucalyptus in Southern California,” by E. N.<br />

Munns, Journ. of Forestry, XVI, 412 (April, 1918). In this paper twenty-six species<br />

are dealt with. A few of the vernaculars are open to possible correction, e.g., E.<br />

polyanthema, which is called “Australian Beech,” perhaps a misplaced label, for<br />

such a name is quite unknown in Australia. E. amygdalina is called “Giant<br />

Eucalypt.” Perhaps E. amygdalina var. regnans—E. regnans—is meant. E.<br />

leucoxylon, “White Wood.” This is a mistake, although it is sometimes called<br />

“White Ironbark.” The author of the specific name regnans (p. 422) is Mueller. E.<br />

goniocalyx, “Box-wood.” Box-wood is not an Australian wood, though “Box” is. E.<br />

calophylla, “Feather-veined Gum.” This is evidently a Californian name for the<br />

“W.A. Red Gum,” but it is descriptive of all the Corymbosae.<br />

One of the conclusions in a useful paper is that E. viminalis is the most frost-hardy<br />

species of the genus that has so far been planted in Southern California, followed by<br />

E. polyanthemos, E. Gunnii, E. bicolor, and E. regnans. It is quite evident, however,<br />

that the original seeds were not obtained from the most frost-resistant localities in<br />

all cases.<br />

(b) Snow.<br />

See Dudley Le Souef, “Effect of Snow on Eucalyptus trees,” (Vict. Nat., 18, 108–<br />

110, 1901).<br />

(c) Wind.<br />

Effect of wind. See Fissility (timbers), Part LIV, p. 208.<br />

See my “Forest Flora of New South Wales,” Part LX, for two remarkable<br />

photographs showing:—<br />

(a) “Wind-blown trees, Stanley, North-west Coast, Tasmania. (These illustrate the<br />

dwarfing or nanism caused by strong sea breezes in exposed situations.)<br />

(b) “A Cypress Pine (Callitris robusta. R.Br.) after a Cyclone, Cambo Cambo<br />

Station, Collarenebri district, N.S.W.” This shows the devastation in a forest,<br />

including the cyclonic or twisting force, and the disintegration of the timber into<br />

long splintery masses.<br />

IV. Parasites.<br />

(a) True Parasites (Mistletoes).<br />

I am indebted to Mr. W. F. Blakely, my Botanical Assistant, for the following<br />

lists, and hope the publication of them will lead to much fuller interest being taken
