TREMANDRACE^E. (Poreworts.) A 

 small order of polypetalous dicotyledons, 

 consisting of heath-like shrubs, all Aus- 

 tralian, with small entire leaves often ver- 

 ticillate, and red blue or rarely white flow- 

 ers on slender axillary pedicels. They are 

 chiefly characterised by regular flowers, 

 with four or five valvate sepals, as many 

 spreading petals, twice as many free hypo- 

 gynous stamens, anthers opening in ter- 

 minal pores, and a free ovary, usually two- 

 celled, with one two or rarely three pendu- 

 lous ovules in each. The order, although 

 small, is perfectly distinct in habit and 

 character, and, though having some affinity 

 with Polygalaceo?, is at once distinguished 

 by its regular flowers ; it has, however, a 

 more remote analogy with the tribe Lasio- 

 petalece of Sterculiacece. 



TREMANDRA. A genus of Tremandra- 

 cea>, conferring its name on the order to 

 which it belongs, and composed of two 

 species inhabiting Western Australia. 

 They are delicate shrubs, covered with a 

 stellate down , and have opposite ovate 

 leaves, axillary purple flowers, a five-cleft 

 calyx, a corolla composed of five petals, 

 ten stamens, two-celled anthers, and a two- 

 celled ovary. [B. S.] 



TREMBLE. (Fr.) Populus tremula. 



TREMBLIN. (Fr.) Briza minor. 



TREMBLING-TREE. Populus trepida. 



TREMELLA. The typical genus of the 

 natural order of Fungi called Tremellini, 

 distinguished by its tremulous gelatinous 

 generally more or less waved and sinuated 

 mass, having an even hymenium without 

 any definite upper or under side, and free 

 from papilla? or tubercles. The species 

 vary greatly in colour, being white bright 

 or pale-yellow, rose-coloured, chocolate, 

 brown, purple, &c. Their form is as varied 

 as their colour, sometimes yielding sinu- 

 ated plates, sometimes brain-like masses, 

 sometimes clubshaped processes, and some- 

 times orbicular bodies or uniform resu- 

 pinate strata. Occasionally they grow on 

 living trees, but more frequently on dead 

 branches, while two occur on the naked 

 ground or amongst grass. T. mesenterica, 

 which is conspicuous in every dead hedge 

 in winter from its orange tint, produces 

 occasionally myriads of conidia. [M.J B.] 



TREMELLINI. A natural order of 

 hymenomycetous Fungi, distinguished by 

 their gelatinous texture, their hymenium, 

 in the more typical forms, covering the 

 whole surface without any definite upper 

 or under side, the sporophores, whicli are 

 often lobed or quadripartite, not being 



packed into a regular hymenium butplaced 

 at very different heights, and the spicules 

 being much elongated. The spores more- 

 over, which are either simple or septate, 

 produce occasionally little offsets at the 

 sides.which may either be secondary spores 

 or spermatia. If secondary spores, the 

 primary must be considered as protospores, 

 analogous to those of Pucciniwi. This 

 opinion is, however, at present merely 

 theoretical. Tremellini occasionally con- 

 tain a nucleus which is not gelatinous, and 

 which has sometimes a cretaceous texture. 

 The species occur almost exclusively on 

 decayed wood, either naked or bursting 

 through the bark. Two species only have 

 at present been described with a terrestrial 

 habit. When dry many of the species 

 shrink up very much, but they recover 

 their original condition perfectly when 

 moistened. Hirneola has several repre- 

 sentatives in tropical climates besides the 

 common Jew's Ear, which seems univer- 

 sally distributed , but the greater part of 

 the order is peculiar to temperate climes 

 of either hemisphere. [M. J. B.] 



TREMENE. (Fr) Trifolium pratense. 



TREMME. (Fr) Agrostis stolonifera. 



TRENTANELLE. (Fr ) Ehus Cotinus. 



TREVESIA. A genus of Araliacew, con- 

 taining a single species from India, a 

 prickly shrub or tree, with large round 

 pinnatisect leaves, and whitish-green 

 flowers in terminal paniculate umbels. 

 The calyx-limb is unequally toothed ; the 

 petals are from four to seven, and the sta- 

 mens from six to nine (generally seven), 

 with cordate anthers. The ovary is five to 

 eight-celled, covered with a large epigy- 

 nous disk ; the styles are the same in num- 

 ber as the cells, but united into a single 

 pyramid at the apex, and surmounted by 

 a bilobed stigma; the fruit is fleshy, wtih 

 five to eight one-seeded cells. [W. CJ 



TREWIACE/E. An order formerly pro- 

 posed by Lindley for the genus Treicia, 

 which he has since, with other botanists, 

 referred to Euphorbiacece. 



TREWIA. The name of a genus of Eu- 

 pltorbiacece, comprising a tree, native of 

 India, with triplinerved leaves, and dioe- 

 cious flowers— the males in racemes, the 

 females in pairs on a branched peduncle. 

 The male flowers have a membranous two- 

 leaved calyx, ultimately reflected ; within 

 this are numerous stamens, placed on a, 

 convex receptacle. The female flowers have 

 a calyx of one membranous sheathing leaf, 

 ultimately falling off; and a four-celled 

 sessile ovary, with the style divided into 

 four feathery stigmas. The fruit is fleshy, 

 with four one-seeded stones. [M. T. MJ 



TRI. In compound words = three; as 

 tricostate, having three ribs ; tricornis, 

 having three horns. 



TRI ADELPHOUS. Having the stamens 

 collected into three parcels. 



TRIAKENIUM. That kind of fruit
