Has. Cheshunt, Archer. 
A remarkably distinct-looking species, most similar to D. Tasmanica, with which it agrees in foliage, but it is 
smaller, with a less-branched panicle, larger campanulate flowers, very much broader segments of the perianth, and 
large oblong berry. The filaments are long and stout, but not so thickened upwards as in D. Tasmanica, and the 
outer series are adnate for half their length to the sepals.

Flores multibracteati, in spicam amentiformem densissime congesti. Perianthium 6-partitum, foliolis 
basi conniventibus, interioribus concavis. Stamina 6, basi perianthii inserta; filamentis linearibus, glabris, 
exsertis; antheris versatilibus. Ovarium 3-loculare; stylo erecto trisulco; stigmate simplici. Capsula 
ovata, lignea, trilocularis, loculicide trivalvis ; loculis polyspermis. Semina pauca, compressa; testa atra, 
crustacea, umbilico nudo; albumine carnoso; embryone transverso. — Plante perennes, habitu proprio ; 
trunco subnullo v. erecto, subarboreo, crasso ; foliis ad apicem caudicis numerosissimis effusis, longissime linea- 
ribus, gramineis, subtriquetris, basibus dilatatis, persistentibus, corticem spurium efficientibus et sepissime resina 
scatentibus ; scapo robusto, simplici, tereti ; floribus albis, parvis; bracteis unguiculatis, imbricatis ; capsulis 
exsertis, brunneis, nitidis. 
One of the most remarkable of Australian genera, some species of which are well known to the colonists as 
“ Black-boys.” One of the larger species, with tall, erect trunks, occurs in Tasmania, where the dwarf kinds are 
more abundant. Brown enumerates seven species, all natives of the eastern and south-eastern shores of Australia 
or of Tasmania, and several others are described from the Swan River Colony. In all, the bases of the leaves are 
persistent, and form a more or less complete spurious bark to the trunk ; they are further, in some species, cemented 
together by a copious exudation of rich, red-brown, fragrant resin.— Leaves very numerous, effuse, narrow-linear, 
pendulous from beyond the middle. Flowers collected into dense cylindrical spikes, 6 inches to 2 feet long, 
sessile, bracteate. Perianth of six obovate, rather coriaceous or scarious leaflets. Stamens inserted at the base of 
the perianth, with long, exserted filaments, and versatile anthers. Ovary three-celled, with many ovules, and a 
long, straight style. Capsules woody, shining, protruding from the amentum, three-celled, three-valved, few-seeded. 
Seeds with a black testa. (Name from £avos, yellow, and peo, to flow ; in allusion to the gum.) 
1. Xanthorrheea australis (Dr. Prodr. 288); trunco arborescente (1-2-pedali?), foliis ancipiti- 
bus, scapo amento elongato breviore, bracteis fasciculos subtendentibus elongatis.—Kunth, En. iv. 649.

Disrris. Victoria. 
Trunk, REA to Gunn, never in Tasmania exceeding 2 feet high. Leaves 2-3 feet long, slightly scabrous. 
Scapes very variable in length, from a few inches to 4 feet high, robust. Spikes a foot or two long. Flowers open- 
ing first on the sunny side of the spike.—The aborigines used to eat the centre of the stem and bases of the young 
leaves, which have a nutty flavour, but are not palatable.
