capsule much exceeded by the bracteoles: seeds many, cylindrical. — SI. t. 127./. 4, 5. 

 Desc. Ft. 4. *. 302. — Flowers yellow, 1\" long. — Hab. Bahamas!, Jamaica!, all coll., 

 common ; Caribbean Islands ! ; [Cuba ! and Mexico ! to Brazil ! and Peru ! ; Galapagos !]. 



2. T. parviflora, Benlh. ! Shrubby, villous ; leaves biglandular at the base (or 

 "eglandular"), ovate, bluntish, coarsely crenate-serrate above the cuneate base, shortly 

 petioled, velvety beneath ; flowers subsessile, free from the petiole: bracteoles linear, entire, 

 nearly equalling the calyx ; calyx hirsute, 5-lobed, a little exceeded by the petals ; capsule 

 half as long as the bracteoles ; seeds few, ovoid-globose. — T. tomentosa, Kth. {non W.) : a 

 monstrosity with 6 petals. — Habit of Me/ochia hirsuta ; calyx 3"'-4'" long. — Hab. Trini- 

 dad!, Lockh., Cr.; [Guiana!, Brazil !]. 



3. T. Pumilea, L. Annual, hirsute ; leaves eglandular, oblong-lanceolate, inciso-serrate 

 above the tapering base, shortly petioled, floriferous clustered : veins excurrent between the 

 serratures ; flowers sessile, inserted into the summit of the petiole ; calyx hirsute, 5 -partite, 

 equalling the linear, entire bracteoles, enclosing the convolute petals : segments linear ; cap- 

 sule nearly as long as the bracteoles: seeds incurved, deeply scrobiculate. — SI. t. 127.,/". 6. 

 — A few inches high, or spithameous ; flowers 2"'-3"' long, tawny : petals clawed, with a

2. TRIACIS, Gr. 



/t ■ 



Calyx campanulate, 5-dentate. Petals 5, sessile at the calyx-throat. Stamens 5, anthers 

 sagittate. Ovary sessile : styles 3, entire below the 6-fid summit : placentas 3. Capsule 

 3-seeded, mediauicide-3-valved to the base : seeds scrobiculate. — A small shrub ; leaves mi- 

 nute, pinnatifld, stipulate ; flowers axillary, bihracteolate, shortly pedicellate. 



This genus is intermediate between Turnera and Piriqueta: it is distinguished from 

 Turnera by its calyx and the capsule-valves of Piriqueta, from the latter by the less divided 

 styles, the inflorescence and habit, and from both by its 3-seeded capsule. 



4. T. microphylla, Gr. — Turnera, Desv. — Habit of Ayenia ; branchlets spreading, 

 rugulose-warty, hairy, glabresceut : inferior internodes much longer than the leaves ; leaves 

 2"'-3'" long, 1'" broad, eglandular, glabrous above, hairy beneath, plaited with impressed 

 lines between the lobes •. lobes 3-4-jugal, revolute ou the margin, ovate, pointed : >>etiole 

 very short; pedicels 1"' long, or shorter, from the axils of clustered leaves; calyx 2"' long : 

 campanulate tube as long as or longer than the oblong, subentire bracteoles : teeth ovate, 

 pointed, 3—4 times shorter than the tube, a little exceeded by the spathulate, sessile petals ; 

 stamens equalling the calyx-tube ; ovary strigosc ; capsule subglobose, exceeding the bracte- 

 oles ; seeds bluntly cylindrical, slightly incurved, minutely scrobiculate : caruncle minute. — 

 Hab. Bahamas!, Swains.; [Cuba!, Haiti]. 



3. TRIBOLACIS, Gr. (n.gen.). 



Calyx clavate, constricted above the base, 5-dentate. Petals 5, sessile, inserted into the 

 middle of the calyx-tube. Stamens 5 : anthers incumbent. Ovary sessile ; styles 3, filiform, 

 entire below the 3-fid summit : placentas 3. Capsule 3-seeded, medianicide-3-valved to 

 the base : seeds scrobiculate. — A suffrutescent, glabrous, rush-like herb ; leaves filiform, 

 sessile, exstipulate ; flowers in a few-flowered , terminal raceme : pedicels short, continuous 

 S-bracteolate at the top. 



This genus approaches Piriqueta. Its stiff habit is quite peculiar, and recalls some 

 Iinaria. 



5. T. jtmcea, Gr. — Root slender, creeping, perennial, with a csespitose tuft of stiff 

 stems and branches ; stem 1' high, 1'" thick or less, much branched at the base, striate- 

 cvlindrical, growing aphyllous below at the time of flowering; leaves distant, 12"'-6'" long, 

 1"' broad, the uppermost decrescent, transformed into bracts ; raceme 6-1 0-flowered, inter- 

 rupted below : pedicels 1'" long ; calyx 4'" long : subcylindrieal base 1'" long, as long as the 

 oblong-linear bracteoles, distinct by a slight stricture from the npper clavate portion : teeth 

 V" Ion"', pointed, traceable downwards, where they are connected by the membraneous part 

 of the tube; petals delicate, convolute, spathulate, 3'" long, shortly exserted ; stamens ad- 

 herent a little to the lowest part of the calyx-base, equalling the calyx : anthers oblong ;
