40 FLORA OF TASMANIA. [Alismacee. 
l. Triglochin triandrum (Mich. Flor. Bor. Am. i. 208); foliis gramineis, floribus pedicellatis, 
staminibus 3-6, fructu subgloboso, carpellis 3 dorso carinatis cum 2-3 septiformibus alternantibus, stig- 
matibus brevibus recurvis.—Z7. N. Zeal. i. 936. T. decipiens, Br. Prodr. 343; Endl. in Plant. Preiss. 
1.53. T. filifolium, Sieb. Di Eesic.; Hook. Ie. Pl. 579. 
Has. Salt-marshes; abundant, Brown, Lawrence, Gunn, etc.—(Fl. Nov.-Jan.) (v. v.) 
Disreis. Australia, from Moreton Island southwards and Swan River; New Zealand, Cape of Good 
Hope; South America, from South Brazil on the east coast, and Chili on the west, southwards ; South 
United States. 
A slender plant, 3 inches to 2 feet high.— Root swollen and bulbous. Leaves narrow, linear, sharp-pointed, 
as long as or shorter than the scape, with membranous sheaths. Scape solitary, flowering part 1-5 inches long. 
Flowers very numerous, minute, on spreading pedicels that lengthen after flowering. Sepals ovate, acute or blunt, 
variable in size and form. Stamens variable in number, and particularly in size. Fruit broadly-ovate or elliptic, 
one line long, of three compressed carpels, alternating with as many flat abortive ones. Carpels with three ridges 
at the back, and very sharp points.—The Tasmanian specimens have sharper sepals than is usual, and the stamens 
are more frequently six. 
2. Triglochin centrocarpum (Hook. Ic. Pl. t. 728); pusillum, cespitosum, foliis filiformibus 
scapo brevioribus, seapis plurimis, floribus breve pedicellatis, sepalis membranaceis valde insequalibus acu- 
minatis obtusisve, stuminibus 3-5, fructu lineari apice truncato, carpellis 3 fertilibus 3 sterilibus alternan- 
tibus linearibus dorso planis tricostatis, costis lateralibus marginalibus basi breviter calcaratis, stigmatibus 
parvis recurvis.— ndl. in Plant. Preiss. ii. 54. (Gunn, 161.) 
Var. 8; fructibus brevioribus brevissime pedicellatis divaricatis. (Gunn, 899.) 
Has. Sandy, moist places; abundant, Guan. Var. B. Georgetown, Gunn. 
Disrmis. Victoria and Swan River. 
An insignificant plant, 1-2 inches high.— Zeaves 4-1 inch long, filiform, narrow, blunt. Scapes numerous, 
rigid and wiry when in fruit, bearing a spike of five to ten minute flowers. Fruit on very short pedicels, linear, 
$— inch long, three-angled or six-angled, the alternate faces much smaller, and formed by the alternate sterile car- 
pels. Carpels very narrow, blunt, with a small, recurved, feathery stigma; back flat, with three ridges; the two 
lateral marginal produced at base each into a short projecting spine.—Swan River specimens are sometimes twice 
a slarge as these, with much longer pedicels to the fruit, but the majority do not differ from Tasmanian. The 
var. B looks a somewhat different plant because of its small, sessile, spreading (not erect) fruit, but I find the same 
size of fruit on long pedicels in Swan River specimens, and both erect and spreading. 
2. Triglochin procerum (Br. Prodr. 343); robustum, elatum, radice tuberibus plurimis, foliis 
gramineis linearibus obtusis sepius supra medium natantibus, scapo solitario, spica elongata, floribus breve 
pedicellatis, sepalis obtusis, staminibus 6, ovariis 6 fertilibus, stigmatibus linearis recurvis papillosis, car- 
pellis 6 sepius obliquis tortisve apicibus divaricatis.—Cycnogeton Hügeli, Endl. in Ann. Vien. Mus. 
i. 210; Plant. Preiss. ii. 55; Icon. t. T3; Gen. Pl. Suppl. p. 1369. 
Var. 8. minor, gracilior, foliis anguste linearibus spica abbreviata. 
Has. Fresh and brackish water ; abundant. Var. 8. In pools dried in summer.—(Fl. Nov.) ( 
DisrarB. Tropical New Holland, Port J ackson, Swan River, and Victoria. 
An extremely variable plant, as Mr. Gunn well remarks, from 1 to 3 teet hi 
The var. 8 is smaller and more slender, growing in sandy 
ing numerous oval tubers 3-1 inch long. Leaves 6 inches to 3 feet long, and 2-2 inches broad, compressed below, 
flat above, linear, blunt, the upper part floating on the water. Scapes solitary, very variable in thickness and 
length, some as thick as the thumb, others as a crow-quill. Spikes long or short, of many, sessile, crowded flowers,
