The above list contains ten of the best ornamental 

 trees. It might he extended indefinitely if all our good 

 trees were included. Tlie ornamental eucalypti and 

 acacias would at least treltle this list, an<l the palms 

 alone would easily double it. Ernest Biiaunton.

TREVfiSIA (after the family Treves di Boniigli of 

 Padua, patrons of botany). Aralii^cea^. About 9 species 

 of small trees or shrubs from tropical Asia and the 

 islands in that region, with large Ivs. either palmately 

 cut and simple or digitately or pinnate compound, and 

 flowers which are rather large fur the family and ])0rne 

 in panicled umbels: petals 8-12, valvate, somewhat 

 thick; stamens S-li^: ovary 8-12doculed: fruit large, 

 ovoid. Greenhouse subject. 



palmata, Vis. \ Gastbnia palmttin, Roxb.). A small 

 tree, with the ends of the branches sparingly prickly 

 and the young parts tomnntose: Ivs. crowded at the 

 ends of the branches, 1-1 H ft. across, palmately 5-9- 

 lobed to below the middle; petioles 1-1>2 ft. long:

TRICALt'SIA (Greek, triple calyx; true of some spe- 

 cies). Bul'iaceie. Here belong the two shrubs from 

 Natal which are cult, in S. Fla. under the name of 



Kraussia. When Kraussia was written for this Cyclo- 

 pedia the undersigned treated it in the manner sug- 

 gested by Bentham and Hooker, Index Kewensis and 

 Flora Capensis. Since then the writer has had access 

 to the Flora of Tropical Africa, which throws a new 

 light on the relationship of these plants. In Vol. 3 of 

 that work Kraussia is made a section of Tricalysia 

 characterized by having the calyx -limb 4-(i-lobed ; tlie 

 other species have a truncate calyx-limb which is cntirf- 

 or nearly so. Tricalysia is a genus of erect or clinildiig 

 shrubs, with small axillary flowers. It cinitalns a few 

 species froni Natal and Madagascar in addition to 21 

 from tropical Africa. The two species UK-'iitioiied be- 

 low have funnel-shaped fls. which are about a quarter 

 of an iuL-h long. Their color is not stated; it is pri)))- 

 ably white. The fls. are borne in cliisti-rs, whifh are 

 much shorter than tJie leaves. It is not ch-jir why these 

 plants should be cultivated at all. Tln^y l>]r.om in S. 

 Calif., but have not bloomed in S. Fla. 



Generic characters of Tricalysia: calyx-tnbe in manv 

 species girt at the base with a single or double epi- 

 calyx of involucral bracts: corolla funnel-shaped or 

 shortly salver - shaped; throat bearded or glabrous; 

 lobes 4-8; stamens 4—8, inserted at the mouth of the 

 corolla; ovary 2doc-uled, rarely .3-loculed. Jfraiis^^ia 

 hi ii^eolafa- is here remove<l to Tricalysia and Hiern is 

 citcil as the author of the combination TriraJi/.sia Jav- 

 nu-ldta, though the combination has probably never 

 been formally made previous to this occasion.

 stigma deeply 2-lobed, lobes revohite: fr. globose, the

 Sonderiana, Hiern {Kraussia coriacea, Sond.).

 wedge-shaped at the base, coriaceous, l%-3% in. long: 

 cymes about 4-lid. ; fls. pentamerous ; pedicels ^-Va

 lobed, lobes revolute. Natal. -^y jj 



TRiCHARIS. A section of Bipcadi. 



TRICHINIUM (Greek, hairy; alluding either to the 

 plant in general or to the tl. -heads). Amarantdcew. A 

 genus of 47 species of Australian herbs or shrubs, often 

 hairy, with alternate narrow or rarely obovate leaves 

 and pink or straw-colored flowers in terminal simple 

 spikes or heads, with shining scarious bracts. Perianth - 

 tube short; segments 5, equal, linear, rigid, usually 

 flumose; stamens 5, but usually 1-3 of them small and 

 antherless: fr. an indehiscent utricle. 



exalt&.tum, Benth. {Ptildtus exaUcttua , Nees). A ten- 

 der perennial, 2-3 ft. high, erect, usually branching 

 above: lower Ivs. 2-5 in. long, oblong-lanceolate rather 

 thick, contracted into a long petiole; upper Ivs. smaller: 

 spikes erect, long-peduncled, at first ovoid-conical, be- 

 coming longer: perianth '% in. or less long, yellowish, 

 with dull red tips. B.K. 25:28 (as T. alopecnroides).— 

 Lately introduced in this country as a greenhouse sub- 

 ject. 



T. Mdnglesii, Lindl.. is perhaps the choicest species. It has 

 violet-puriile fls. in large pyramidal heads 3 in. long and 2 in, 

 wide at base. It could prolj:ddy be grown as a summer annuiil.

TRICHLdRIS (Greek for three and green). Gravii- 

 )i.em. Under the name of Chloropsis, or O'hloridopsis, 

 Btanchardidna, seedsmen offer a tender pHrenuial 

 ornamental grass, growing l-23'2 ft. high and useful for 

 edgings. Its proper name is Trichloris Blanchardiana, 

 Hackel. It comes from Argentina. There are four 

 other species of Trichloris, 2 from Chile and 2 from the 

 southwestern U. S. There are no such recognized ge- 

 neric names as Chloropsis and Chloridopsis. Trichloiis 

 has the flowers arranged in long rather slender mostly 

 erect sidkes which are umbellate or panicled: spike- 

 lets 1-3-fld., the sterile bracts produced into prominent 

 awns. T. Bla lU'hardiaiKt is a useful grass, its umbel- 

 like clusters of soft - awned silvery spikes being very 

 pleasing. It is readily grown from seeds. i^ jj 3 



TRICHOCfiNTRUM (Greek, hair and slender; allud- 

 ing to the long, slender spur). Orchiddcece. A small 

 genus allied to Rodriguezia (Burlingtonia). The plants 

 grow in dense matted tufts. Pseudobulbs very small, 

 each bearing a broad, fleshy leaf. Inflorescence a few- 

 fld. raceme on which usuall}^ only one flower opens at 

 a time: sepals and petals free, spreading; labellum 

 larger, spurred, with 2 lateral lol>es and a 2-parted mid- 

 dle lobe; column short: pollinia 2, on a wedge-shaped 

 stipe. Sixteen species. Epiphytes of dwarf stature, 

 j^rowing best on blocks ; free-flowering ; they suffer 

 from too much water at the root; give them a warm- 

 house temperature. Prop, by division.

 3 in. long, tufted: fls. on short peduncles, 2 in. across; 

 sepals and petals obovate-lanceolate, inside maroon- 

 brown, with greenish tips, outside greenish; labellum 

 su])quadrate, white, with a large purple sjiot on each of 

 the lateral lobes. Brazil. B.M. 5088. A. F. 6:000. 



tigxlnum, Lindl. and Reichb. f. Similar in habit to 

 the preceding: lvs. oblong, obtuse, speckled with red: 

 fls. pendulous, nearly 3 in. across; sepals and petals 

 broadly linear, yellow, speckled with red: labellum
