A BIPINNATE CYCADEA FROM N.E. AUSTRALIA. 
By BERTHOLD Seemann, Pu.D., F.L.S. 
This plant, certainly the most singular Cycad brought into notice 
since Stangeria, with its Lomaria-like venation, was’ re-discovered by 
Mr. Walter Hill, Director of the Brisbane Botanical Gardens, and is to 
be called, after his Excellency Sir George Bowen, Governor of Queens- 
land, Bowenia. It has the vernation of Cycas, the venation of Zamia. 
A living plant of it is now at Kew, and worth examining. The stipes 
is hirsute unarmed, and the leaf bipinnate and glabrous, the pinne 
ing opposite, the pinnule alternate or opposite, unilateral, rhom- 
boid-lanceolate, acuminate, serrated towards the apex, attenuate at 
the base. I possess a Macrozamia from N.E. Australia, with bifur- 
cate leaflets, given to me by Mr. Charles Moore; but that is a very 
different plant. At first sight the leaf of this living Bowenia looks like 
a branch of Geitonoplesium cymosum, or some Dammara-like Podocarpus. 
Bowenia, found by Mr. Hill on the banks of the Mackay, Rocking- 
ham Bay, N.E. Australia, was met with on the 2nd of July, 1819, by 
Allan Cunningham, one of whose specimens is preserved in the British 
Museum, another was given, many years ago, to Mr. J. Smith, of Kew. 
Tn a list of the plants A. Cunningham collected in the tropical parts of 
New South Wales, as Queensland was then called, and forwarded to 
Sir Joseph Banks, we read, under n. 289, the following :—‘‘ droidee. 
A strong herbaceous plant appearing [to be] of this natural family, with 
3-pinnate, obliquely elliptical, acute leaves (without fructification). 
Shaded woods, Mount Cook, Endeavour River. July 2, 1819. (Can 
this bea Fem ?!)" On turning to n. 289 of the collection alluded to 
in the British Museum, I find a single frond, which is forked, and has 
below the forking two leaflets, but fifteen leaflets on each of the branches 
(pinnae). The entire length of these branches is 18 inches. The leaflets 
are larger than those of the living plant at Kew, ovate-rhomboid, 54
