6» FLORA OF TASMANIA. [Butacea. 
Disteib. New South Wales and South-eastern Australia. 
A tall, handsome species, 2-4 feet high, exuding copiously a balsamic gum, that smells of turpentine and 
somewhat of Mangos {Gunn).— Branches and branchlets usually pubescent and covered with tubercles, each con- 
taining an oil-gland, but sometimes smooth. Leaves pinnate ; petioles stout, |-f inch long, often flat and dilated ; 
leaflets two or three pair, more or less obovate-lanceolate or obovate-spathulate, membranous or coriaceous, their 
apices acute, blunt, rounded, retuse, or in broader leaflets bi-trifid, studded with large glands, very variable in 
length and breadth, $~| inch long, generally with an evident prominent midrib. Flowers very numerous, pink, 
variable in size, similar to those of B. pilosa.— Narrow-leaved states closely resemble B. anethifolia, A. Cunn., 
of New South Wales. The membranous state of this, with spathulate, broad, retuse, or lobed leaflets, looks quite 
distinct from any of its congeners, but Gunn's suites of specimens show that it passes directly into the Mowing ; 
it is the B. dentigera of Dr. Muller, and is also found in South-eastern Australia. 
6. Boronia Gunnii (Hook, fil.) ; glaberrima, erecta, ramis ramulisque lfevibus, petiolis gracilibus, 
foholis 2-4-jugis lineari-lanceolatis acutis acuminatisve planis enerviis obscure glanduloso-punctatis, flo- 
ribus amplis.— B. tetrandra, 7 grandiflora, H.f. in Journ. Bot. ii. 419. {Gunn, 8.) (Tab. X.) 
Hab. Rocks on the South Esk River, near Launceston, Gunn.— (El Nov. Dec.) 
Everywhere glabrous, 2-4 feet high. Brandies smooth, smelling powerfully of rue or tansy. Leaves nume- 
rous ; petioles rather slender, f-1 inch long. Leaflets linear-lanceolate, flat, rather membranous, acute or acuminate, 
nerveless, obscurely glandular. Flowers large, often § inch across, abundant, on rather long pedicels. Filaments 
pilose, glandular at the back towards the anthers. Seeds oblong, black.— Plate X. A. Leaf of the form figured.

tical section of ditto; 12, seed; 13, section of ditto, showing the albumen in its membrane; 14, section of 
albumen, showing the embryo :— all magnified. 
7. Boronia citriodora (Gunn, MSS.) ; erecta, glaberrima, v. ramulis Iambus puberulis, petiolis 
brevmsculis crassis, foliolis 1-2-jugis lineari- v. obovato-lanceolatis acutis crassis coriaceis enerviis obscure 
punctatis, floribus breve v. longe pedicellatis.—B. variabilis in pari. Booh. Comp. Bot. Mag. i. 277 et Journ. 
Bot. ii. 418. {Gunn, 667, 894?) 
Hab. Common in alpine districts, in quartzy sand and peat, elev. 2-4500 feet : Black Bluff Mountain 
Fatigue Hill, Lake St. Clair, Hampshire Hills, Gunn.-{n. Jan. Feb.) (Lemon plant.) 
As handsome a species as B. Gunnii, but not so tall 5 it is very difficult to distinguish it from that plant, except 
by the strong and delicious smell of lemons, the fewer, far more coriaceous leaflets, and shorter petioles. Gunn 
observes that the seeds are larger and longer in this, but the difference is slight, and can only be detected by com- 
parison. Gunn's 894 ? are small specimens of the same (as he suspects himself). 
Gen. VI. ACRADENIA, Kippist. 
Calyx 5-8-partitus. Vetala 5 (rarius 4), imbricata. Stamina 8-10, alterna breviora; filamentis 
glabns. Ovaria 5, villosa, apice glandula instructa; ovulis 2, collateraliter pendulis. Stylus 1, erectus. 
Capsula 5-cocca, coccis compressis truncatis breviter cornutis rugosis, endocarpio non secedente.— Frutex 
%-U-pedalis ; foliis oppositis, trifoliolatis, glanduloso-pustulatis j floribus cymosis, albis. 
A very remarkable plant, fully and well described and figured in the 21st volume of the Linna^an Trans- 
actions by Mr. Kippist, who established the genus, and of whose analvsis I have availed m Y self in the generic and 
specific descriptions. (Name from c 
each carpel.)
