TRIUMFETTA (named after Giov. Batt. Trionfetti,

Paroquet-Bur. ORD. Tiliacew. A genus comprising about 
forty species of widely-dispersed, stove or greenhonse, 
stellate-pubescent herbs, sub-shrubs, or shrubs. Flowers 
yellow, axillary or leaf-opposed; sepals and petals five; 
stamens numerous. Leaves entire, or three to five-lobed, 
serrated. Several of the species have been introduced; 
but none of them are worth cultivating for ornament. 
TRIURIDEZ. A natural order of very slender, 
white or discoloured herbs, inhabiting 
tropical forests of Asia and America. 
Flowers minute, racemose or spicate, 
moncecious or dicecious, rarely unisexual ; 
pedicels bracteate ; perianth three, four, 
six, or eight-parted, hyaline; segments 
connate at base, valvate, the tips often 
caudate ; stamens few, various in num-- 
ber, sessile in the base of the perianth; 
anthers four-celled, two-valved. Carpels 
many ; ripe ones obovoid, coriaceous and 
indehiscent, or two-valved, one-seeded. 
Leaves wanting, or bract-like, alternate, 
and nerveless. Stem simple, rarely di- 
vided, filiform, straight or flexuous, erect. 
The order comprises only a couple of 
genera — Sciaphila and Triwris — and 
about sixteen species.

to the three-celled, triangular capsule).

Composite, A genus embracing about 
thirty species of stove or greenhouse 
herbs or shrubs, of variable habit, natives 
of Central and South America and the 
West Indies. Flower-heads yellow or 
whitish ; florets bilabiate, the outer lip 
three-toothed, the inner bipartite or bifid; 
involucral bracts often two-seriate; receptacle small; 
pappus bristles copious. Leaves alternate, sometimes 
decurrent. The two members of the genus which have 
been introduced are described below. Both thrive in 
a compost of sandy loam and leaf mould. T. divaricata 
auriculata requires the protection of a warm greenhouse 
in winter; it may be increased by cuttings, inserted 
in sand, under a bell glass, in May. Seeds of T. senecioides 
should be sown in the open ground, in April. 
T, auriculata (eared). A synonym of T. divaricata auriculata. 
T. divaricata auriculata (divaricate, eared). fl.-heads 
white or yellowish-white ; involucral scales acuminate. August 
and September. J. sessile, oval-lanceolate, acuminate, denticu- 
late, nearly glabrous, dilated at base into obtuse auricles. Stems 
climbing, suffruticose. A. 1}ft. Brazil, 1827. (B. M. 2765, under 
name of T. auriculata.) 
T, senecioides (Senecio-like). fi.-heads white, solitary, on long 
duncles ; involucral scales in two or three series. August and 
rpm l. all sessile and amplexicaul, oblong, sinuate-lobed,
