 (Tetrapteris acutifolia ; Cavan. Diff. n. 595. t. 261.) — 

 Leaves ovato-la^iceolate, acute, fmooth. Panicle terminal.

8. T. citrifoUa. Orange-leaved Triple-wing. Swartz 

 Ind. Occ. 857. Willd. n. 8. (Tetrapteris injEqualis ; ■ 

 Cavan. Diff. n. 594. t. 260. Acer fcandens tricoccos, ■ 

 foliis citri, flore luteo minore ; Plum. Ic. 9. t. 16.) — 

 Leaves ovate, acute, fmooth. Umbels axillary, ftalked. 



Capfules W'ith four wings ; the two lowermoft fmalleit 



Native of woods on the mountains of Jamaica. The 

 flirnbby Jiem climbs to a great height, with very long, 

 round, flexible, fmooth branches. Leaves ftalked, three or 

 four inches long, flexible, with feveral lateral ribs. Flowers 

 fmall, yellow, in axillary and terminal panicled umbels. 



Dr. Swartz very juftly obferves, that the Tetrapteris of 

 Cavanilles is no diilinft genus from Triopteris. Our fecond 

 fpecies, having but three wings to the whole aggregate 

 fruit, or a fimple circumambient wing to each capfule, may 

 be thought to anfwer ill to the idea of this genus. 



Tkiopteris, in Gardening, furnilhes a plant of the 

 climbing woody exotic ftove kind from the Weft Indies, 

 of which the fpecies cultivated is the Jamaica triopteris 

 (T. jamaicenfis). 



It is a tender exotic plant, which conftantly requires the 

 proteftion and warmth of a greenhoufe or ftove in this 

 chmate. 



Method of Culture — This plant is propagated and in- 

 'creafed by leeds, cuttings of the branches, and layers. In 

 ftriking roots, the cuttings will be greatly aflifted by the 

 ufe of a hot-bed of tanners' bark. The plants, after they 

 are raifed, are always to be kept in pots, which are to be 

 placed amongft thofe of the greenhoufe or ftove kinds. 

 They (hould have occafional waterings during hot -.veslher. 



They afford a defirable variety in colleftions of the above 

 kinds of plants. 



TRIORCHIS, a word ufed by fome to exprefs a man 

 who has three tefticles. 



It is alfo ufed as the name of a buzzard ; and of a plant, 

 called ladies' traces. 



TRIORS, or Triers, iu Law, fuch as are chofen by 

 the court to examine whether a challenge made to the panel 

 ot jurors, or any of them, be juft or not. 



The triors, m cafe the firft man called be challenged, are 

 two indifferent perlons named by tiie court ; and if they 

 try one man and find him indifferent, he (hall be fworn ; 

 and then he and die two triors fhall try the next ; and 

 when another is found indifferent and fworn, the two triors 

 (hall be fuperfeded, and the two firft fworn on the jury 

 Hiall try the reft.
