Description.

Doubtful species.note

E. Bowmani, F.v.M., in B.Fl. iii, 219 (1866). Named in honour of Edward Macarthur Bowman. He was the eldest son of Dr. James Bowman, of Ravensworth, Hunter River, and nephew of Mr. James and Sir William Macarthur, of Camden Park, New South Wales. He obtained his botanical training from the latter gentleman.

Notes supplementary to the description.

Bentham (loc. cit.) says: “I have some hesitation in describing the species without having seen the fruit.”

It is indeed imperfectly known. Only a few leaves, buds, and anthers of the type are in existence, at all events in Australia.

Range.

QUEENSLAND, where it was collected by the late E. Bowman in only one locality, which may have been the Suttor River, where Bowman collected other Eucalypts; but this is surmise.

Affinities.

1. With E. hemiphloia, F.v.M.

“Probably includes E. Bowmani, described from insufficient material.”—(J. G. Luehmann, Proc. Aust. Adv. Science, vol. 7, p. 526, 1898.)

I think this opinion is the correct one, on the material available. It is, at all events, closely allied to E. hemiphloia. I have no proof that it is a distinct species, and publish the drawing and these few notes in order that the origin of E. Bowmani may, if possible, be traced. I do not think any useful purpose would be served in discussing further, at present, the possible affinities of this plant.

2. With E. hemiphloia, var. albens, and E. cladocalyx, F.v.M. (corynocalyx).

Bentham (loc. cit.) says: “It seems to be allied to E. albens and E. corynocalyx, but differs from both in the shape of the flowers.”

3. With E. siderophloia, Benth.

Chiefly different from E. siderophloia in less shining leaves with about equal numbers of stomata on each side, mostly solitary umbels on a broadly-compressed stalk, absence of stalklets, the lid not long-pointed, the filaments while in bud more twisted, and possibly also in bark and fruit. The tree from Mount Elliott referred to by Bentham under E. Bowmani, belongs to E. drepanophylla.—(Under E. siderophloia, in Mueller's “Eucalyptographia.”

4. With E. Baileyana, F.v.M.

Under E. Baileyana, F.v.M., Mueller, in “Eucalyptographia,” points out certain differences between that species and E. Bowmani, but inasmuch as Mueller himself included two species under E. Baileyana,note his figure being a composite one, with fruits of E. Baileyana and flowers and leaves of E. eugeniodes, the comparison in question is of no value. It has no close affinity to E. Baileyana.
