112 FLORA OF TASMANIA. [Rosacea. 
Very similar indeed to the A. dealbata, and probably only a state of that plant, though looking very different 
when seen beside it. The present never forms so large a tree as A. dealbata, is of a dark lurid hue, has golden- 
yellow young shoots, and the pod is narrower, more torulose, more or less pubescent, with thicker margins, more 
coriaceous valves, constricted between the seeds, so that the pod is moniliform, and it has larger seeds. 
For many valuable remarks on the Tasmanian Acacia, see an article by Mr. Gunn in the second volume of 
the 'Tasmanian Journal of Natural Science.' 
Nat. Ord. XXVII. ROSACEA. 
Of all the large natural families of flowering plants that are widely diffused over the globe, this is 
one of the most scantily represented in Australia. Including the subfamily Chrysobalanea (which presents 
one species of Petrocarya in the Tropics and two of Stylobasium in the south-west coast), scarcely a dozen 
species have hitherto been found in the whole continent, and they belong to six genera, of which four, 
Geum t Potentitta, Rubus, and Alckemilla, are cosmopolitan; a fifth, Acana, is almost confined to the 
Southern Hemisphere, and Cep/ialotus (the Australian "Pitcher-plant") is peculiar to the neighbourhood of 
King George's Sound, in South-western Australia. It is remarkable that both the species of Alchemilla 
are English, one the A. arvensis, originally detected by Mr. Brown, and the other A. vulgaris, found, 
according to Dr. Mueller, on the Alps of South-eastern Australia. 
Gen. I. KUBUS, L. 
Calyx explanatus, ebracteolatus, persistens, 5-lobus. Petala 5-7, calyce inserta. Stamina numerosa. 
Ovaria receptaculo inserta, 1 -ovulate. Drupa succosee, receptaculo subcarnoso v. spongioso insertse. 
Only five or six species of this cosmopolitan genus are found in Australia, of which three are tropical species 
and also Indian ; one is confined to New South Wales, and one, R. Gunnianus, is only found in Tasmania.— Sub- 
scandent or suberect shrubs, rarely creeping herbs, often prickly, with alternate, simple, lobed, ternate, digitate or 
imparipinnate leaves, adnate stipules, panicled or corymbose, rarely solitary, flowers. Calyx without bracts, with 
five spreading lobes. Petals five. Stamens numerous. Ovaries numerous, rarely (in R. GumUamu) definite in num- 
ber. Fruit formed of small, cohering, fleshy drupes, attached to the dry or spongy receptacle. (Name of uncer- 
tain origin.) 
1. Rubus macropodus (Seringe in DC. Prodr. ii. 557) ; aculeatus, suberectus, ramulis pedunculis 
petiolis calycibus foliisque subtus cano-tomentosis, foliis pinnatisectis, foliolis 2-3-jugis rhombeo-ovatis 
obovatisve supra pilosis duplicato-crenatis terminali margine integro v. lobato, floribus axillaribus termi- 
nalibusque, pedunculis unifloris v. paniculatim ramosis, lobis calycinis lanceolatis acuminatis petalis rubris 
longioribus.— R. ribesifolius, Sieb. PL Exsicc. No. 192. {Gunn, 33.) 
Hab. Very common in many parts of the Colony.— (Fl. Dec, Jan. ; fr. Feb.) 
Distrib. East coast of Australia, from Stradbrooke Island to Melbourne. 
A small, slender, prickly shrub, with tomentose branches, peduncles, petioles, and calyx, and which has 
snow-white under-surfaces of the leaves.— Leaves 2^ inches long, pinnate, with one or two pairs of leaflets, 
which are rather coriaceous, wrinkled, hairy above, ovate, obovate, or rhomboid, entire or lobed, rather sharply 
doubly or trebly crenate, blunt or acute ; the terminal larger, and more usually lobed. Pedicels slender, generally 
long, axillary, one- or more flowered, or terminal and forming many-flowered panicles. Flower* |-f inch across. 
Calyx woolly, its lobes lanceolate-acuminate, longer than the red petals. Stamens as long as the petals. Fruit not 
very large, according to Gunn, but of a pleasant flavour. 
2. Rubus Gunnianus (Hook. Ic. Plant, t. 291); inermis, repens, glaberrimus, foliis simplicibus
