fimple, ovate, emarginate. Branches fpinous." — Native of 

 the Eaft Indies. Fruit a berry of three cells, with nfeeJ in 

 each ; hence this plant fecras intermediate between Tric/iilia 

 and Limonia. Willdnno'W. V/c know nothing of it, but 

 there appears little reafon to place it here. 



The gcxmiTrichdia is fufficiently natural, notwithftanding 

 the aberrations of ftrufture in the neflary, or Jlamens, and of 

 number in other parts of the_^'?c':y.-'r. The fpecies ai-e by no 

 means well deterniined, or corre£lly nsmed. One alone has 

 appeared in the Ei ropean ftoves, nor are well-afcertaincd 

 fpecimens frequent in colleftions. The prefence or abfence 

 of axillary glands on the leaves, and the ftrufture of the part 

 bearing the anther:, whatever it may be called, feem to pro- 

 mife the beft marks of fpecific diftinftion. The feeds in 

 T. glandulofa, the only one whofe fruit has fallen under our 

 examination, are each inclofed in a rigid, elaftic, permanent, 

 bivalve tunk, whofe outfide is clothed with red pulp. Whe- 

 ther this be precifely the cafe in the reft, the defcriptions of 

 authors are not exaft, nor confiilent, enough to help us to 

 determine.

Eff. Ch. Calyx in five deep linear fegments. Stamens 

 connedtcd at their bafe, without teeth. Anthers of two 

 cells. Stigma capitate. Capfule without valves, fingle- 

 fecded, inclofed in the converging bafe of the calyx, whofe 

 fegments are fpreading and feathery. 



The fpecies of this genus are herbaceous, generally pe- 

 rennial, with alternate leaves. Flowers terminal, capitate 

 or fpiked, each accompanied by three membranous fnining 

 hrahsas. The hairs of the calyx, at firft: clofe, fubfequently 

 become extended, and give the fegments a feathery afpeft. 

 Trich'mium is truly, as its learned author obferves, very 

 clofely related to Ptilotus ; fee that article. We {hould 

 indeed feel no fcruple in confidering them one genus. Per- 

 haps they ought ftriftly to be referred to the cTafs Monadel- 

 phia, or at leail they, and their Linnaean allies Gomphrena, 

 Achyranthes, Celofia, &c. fhould be indicated at the head of 

 that clafs, for the convenience of young botanifts. Why 

 the latter were not all placed there by the author of the 

 fexual fyftem, to the great relief of his fifth clafs, can only 

 be attributed to his peculiar idea of the ftruft tre of tlieir 

 flowers. He calls a nellarlum, what Mr. Brown efteems the 

 united bafe of their filaments ; but we believe an enlarged 

 confideration of the whole tribe will juftify the latter 

 opinion. 



1. 'T.fuftforme — Leaves linear, very narrow, fmooth as 

 well as the branches. Stems numerous. Root fpindle- 

 thaped. Heads of flowers nearly ovate. Brafteas acute, 

 fingle-ribbed. — Gathered by Mr. Brown, in the tropica! 

 part of New Holland. 



2. T.gracile. — Leaves linear, very narrow, fmooth. Stem 

 nearly fimple. Head of flowers almoft globular. Brafteas 

 obtufe, riblefs. Filaments unequal. — Found in the fame 

 country. 



3. T. Jiflans. — Leaves linear, very narrow, fmooth as 

 well as the branches. Spike elongated, rather lax. — From 

 the fame country'. 



4. T./patnlatum Radical leaves obovato-fpatulate, flat, 



Imooth. Spike cylindrical. — Gathered by Mr.. Brown in 

 Van Dlemen's ifland. 



5. T. miurocepbalum. — Stem-leaves lanceolate, wavy, 

 Imooth as well as the angular branches. Spike oT^long, 

 with a woolly ftalk — Native of the fouth coall of New 

 Holland. 



6. T. incanum. — Le:ives lanceolate, hoary and downy ns 

 well as the round branches. Spikes nearly ovate, lateral as 

 well as terminal. — Gathered b) M. Baudin, on the weil 

 cOcifl; oi Nev/ Holland. 



We have feen r j fpecimens of this genus, any more than 

 of Ftilotiis above-: 'le.itioned. 



TRICHIRI, in Geography, a fmall ifland in the Grecian 

 Archipelago , 5 n-ilcs E. of Specla. 



TRICHLSnOS, from Sp.|, the hair, in Surgery, a ca- 

 pillary f.fl"nre, or fra'^ure of the flcuU, fo called from its 

 being fo fine as to refemble a hair put upon the bone. 



TRICHIURUS, in Ichthyology, a genus of the order 

 of Apodes ; the charafters of which are, that the head is 

 extended, with lateral opercula or gill-covers ; that the teetli 

 are enfif.rm, and femi-fagittated at the apex or tips ; that 

 it has feven branchioftegous or gill-membrane rays ; that 

 the body is compreffed i.id enfiform, and the tail fubulated, 

 without any fin : whence it is called kpturus, and in Englifli 

 needle-tail. There are two 



Species. 



Lepturus or Argenteus; Silvery Trichiurus. With the 

 lower jaw longer than the upper ; and equally diftinguilhed 

 by the fingularity of its fliape, and brilliancy of its colour ; 

 the body very coniprefied, tapering towards the extremity, 

 and terminating in a fine point : the whole body, except the 

 fins, of a bright filver-colour ; the head narrow and the 

 mouth wide ; the lateral fine of a gold-colour, commencing 

 at the gills and continued to the tip of the tail ; the dorfal 

 fin moderately wide, tranfparent, and of a yellowifli tinge, 

 commencing almoft immediately behind the head, and termi- 

 nating near the end of the tail in a mere membrane, the 

 other parts being ftrongly radiated ; the peroral fins imall 

 and of an oval fhape ; without any direft vent-fin, but hav- 

 ing a feries of very fmall naked fpines or rays, about no 

 in number, continued from the vent, which is fituated about 

 the middle of the body, to nearly the tip of the tail. Its 

 general length is from two to three feet : it is faid to be 

 very voracious, fwims with rapidity, and in the purfuit of 

 its prey fometimcs leaps into fmall veffels, which happen to 

 be failing by it. It is a native of the rivers and larger lakes 

 of South America, and is confidered as an eatable fi(h : it 

 is alfo found in fome parts of India and in China. 



Indicus, or FleSricus, or Fufcus ; Brown Trichiurus. 

 With jaws of equal length ; nearly equal in fize to the pre- 

 ceding, but different in the conformation of the jaws, which 

 are of equal length, and in the form of its teeth, which an.- 

 very minute ; the tail lefs flender and fliarp, and the colour 

 of the whole fifli pale brown, variegated with fpots of a 

 deeper caft : a native of the Indian feas, and poflefling a 

 degree of eh'dlrical power.
