Graminee.] FLORA OF TASMANIA. 107 
l. Anthistiria australis (Br. Prodr. p. 200); culmis teretibus vaginisque glaberrimis, foliis gla- 
bris scaberulisve, glumis spathisque imberbibus.—4An var. A. ciliate? (Gunn, 591.) (Tas. CLVI.) 
Has. Abundant throughout the Island.—(Fl. Oct.—Dec.) (v.v.) Colonial name, “ Kangaroo Grass.” 
Disrris. Throughout Australia (India, Abyssinia, and South Africa ?). 
A tall, glabrous, smooth Grass, 1-3 feet high.—Culms leafy. Leaves smooth or scabrid. Ligula membranous. 
Spathes 2 inches long, with long, straight points. Glumes of outer spikelets acuminate, j inch long.  Pedicel of 
central spikelets with a whorl of brown hairs at the top; two lateral male spikelets with subulate, almost awned 
glumes. Outer glume of central spikelet with a rigid, brown, flexuose, bent, strong awn, 13-2 inches long. — This 
appears probably to be a glabrous state of the widely-diffused 4. ciliata.—PLATE CLVI. Fig. 1, fascicle of spike- 
lets in bract; 2, lower spikelet; 3, lateral of the three central spikelets; 4, central hermaphrodite spikelet; 5, her- 
maphrodite flower; 6, sguamulse, stamens, and ovary :—all magnified. 
Gen. VI. HEMARTHRIA, Br. 
Spica compressa, semiarticulata. Spieule quovis articulo utreque fertiles, binate; altera (inferior) 
sessilis, per glumam superiorem rachi agglutinata ; altera (superior) pedicellata, pedicello cum rachi arcte 
connato, glumis liberis. Flores hyalini, mutici; inferior unipaleaceus, neuter ; superior bipaleaceus, herma- 
phroditus. Squamule 2, truncate, glabree.—Gramina ramosa ; foliis planis; ramulis monostachyis, subfas- 
ciculatis v. simplicibus. 
A very curious genus of Grasses, natives of Southern Europe, Australia, India, South Africa, and North Ame- 
rica, belonging to a section of the Natural Order that has usually a jointed rachis to the spike, which is however 
hardly the case in Hemarthria.—Inflorescence spiked. Spikelets two together, the lower sessile, the upper apparently 
so also, but seated on a flat pedicel, which is attached throughout its whole length to the rachis of the spike. 
Glumes two, the inner (upper) one of the lower spikelet attached by its back to the rachis of the spike; glumes of 
the upper spikelet both free. Flowers included, two in each pair of glumes; the lower of one palea, neuter; upper 
of two pales, hermaphrodite. Scales two, truncate. Stamens 3. (Name from ju, half, and apOpos, a joint; in 
allusion to the structure of the spike.) . 
1. Hemarthria uncinata (Br. Prodr. p. 207); rigida, culmis strictis foliosis subcompressis gla- 
berrimis, foliis subbifariis patulis brevibus basi vaginisque parce ciliatis, spica angusta elongata erecta, 
gluma superiore apice hamata. (Gunn, 417.) 
Haz. Coasts of the northern parts of the Island, Gunn.—(Fl. Dec.) 
DisrriB. Australia. 
This is, I believe, a littoral Grass, forming dense tufts.— Culms creeping, very hard and tough, leafy below 
3 inches to a foot high, quite smooth and glabrous, compressed, often curving. Leaves distichous, coriaceous, 
smooth except at the base, where the margins, as also of the sheaths, are ciliated; blade 1-6 inches long. Spike 
13-4 inches long, narrow, slender. Spikelets closely pressed to the rachis, hardly imbricated, green or purplish, + 
inch long. Outer glumes flattish, nerved, acuminate, cuspidate; inner keeled, with an acuminate point, terminating 
in a sharply reflexed point. Palee membranous. ; 
Gen. VII. HIEROCHLOE, Gmel. 
Spicule 3-flore ; floribus lateralibus masculis, intermedio hermaphrodito. Glume 2, carinatee, sub- 
equales. Palee 2, mutice v. inferior aristata, carinata ; arista terminali v. dorsali, recta v. incurva, brevi. 
Squamule 2, bilobe. Fl. d. Stamina 3. Fl. $. Stamina 2. Caryopsis libera, paleis obtecta.—Gramina 
odora ; foliis planis v. involutis ; spiculis paniculatis, nitidis, majusculis.
