1. With E. Sieberiana.

As regards the vernacular names in the “Flora Australiensis,” Cunningham's name of “Blackbutt” is a misnomer, and has probably arisen from confusion of the species with the “Mountain Ash” (E. Sieberiana), and the name of “Mountain Ash” for E. hæmastoma has probably arisen through too close reliance upon herbarium specimens, those of E. hæmastoma and E. Sieberiana being frequently difficult to discriminate unless complete material be available.

As compared with E. Sieberiana, there is a close affinity in juvenile foliage. See E. Sieberiana, p. 306.

2. With E. virgata, Sieb.

Herbarium specimens sometimes exhibit a good deal of similarity. I have a flat-topped fruit (not quite ripe) of the large-fruited kind of hæmastoma from Peat's-road, Hawkesbury River, which was named E. virgata by an excellent authority.

3. With E. Luehmanniana, F.v.M.

The juvenile leaves present a good deal of resemblance. There is a closer resemblance between typical hæmastoma and Luehmanniana, variety altior, which it may be sufficient to draw attention to.

4. With E. coriacea, A. Cunn.

The large-fruited or typical hæmastoma may resemble those of E. coriacea a good deal, but the venation of the leaves is different. E. hæmastoma has clean white stems much after the appearance of E. coriacea.

5. With E. Gunnii, Hook, f., var. maculosa.

This will be dealt with when the variety is reached.

In 1901 (Proc. Linn. Soc., N.S.W., p. 125), Mr. Deane and I described, under the name of E. hæmastoma, Sm., var. montana, a shrubby plant only 2 or 3 feet high, from Mt. Victoria, collected by myself. The bark of so small a shrub was no guide, and the blood-red rims decided us to place it with E. hæmastoma—a pardonable error, as it obviously strongly resembles that species.

Since then, however, I have obtained typical E. amygdalina, var. nitida, and I find that these specimens precisely match Gunn's No. 808, e.g., Currie's River, Tasmania. The pale-brown fruits with the dark red-brown rims arrest attention. The only point in which I can distinguish the Mt. Victoria specimens from those of Currie's River consists in the more obvious oil-glands of those from Mt. Victoria, but this may be in a measure owing to the age (over 60 years) of the Tasmanian specimens. The similarity of the specimens is remarkable when it is borne in mind that the Tasmanian specimens are mostly from the sea-coast, while Mt. Victoria is an inland mountain locality. In a papernote I have given very definite evidence of the absolute similarity of many Tasmanian and New South Wales forms, and this is an additional example.

E. hæmastoma, var. micrantha, differs in the erect, less falcate foliage of E. amygdalina, var. nitida. Both forms show oil-dots very abundantly. E. amygdalina, var. nitida, shows these dots far more abundantly than E. hæmastoma, var. micrantha, as a rule, whose leaves are generally thicker, but in mountain specimens it is sometimes not possible to separate them on these grounds.

The fruits are less brown, less sessile, and with a rather more marked rim than those of var. nitida.

As regards amygdalina generally, the rims of the fruit are thinner; amygdalina has fibrous, and hæmastoma a smooth bark; but in dwarf mountain forms it is sometimes difficult to speak about bark.
