bractlet การใช้

• It bears several yellow flowers contained in a cuplike unit of fused bractlets.
• The lanceolate shaped bractlets are in two series, with the apices acuminate in shape.
• Between the sepals are five narrow bractlets.
• Each flower is cupped by small, clear bractlets and has pointed greenish brown tepals.
• But unlike other violets, it has conduplicated leaf blades, strong and oblong lanceolate to broadly elliptical lobes with blunt tips, and large basally-fused pedicel bractlets.
• The flowers are 60 70 mm long, yellow or green in color but flushed with red or purple shading, as well as the bractlets, giving an overall darker appearance.
• "Aloysia fiebrigii " is distinguished by whorled, arcuate leves, short spikes ( 7-17 mm long ), short calyces 1.2-1.6 mm long, and bractlets approximately the same length as the calyx.
• :Branches angled, dull, glabrous, pale; branchlcts similar, sparsely glandular; leaves opposite, petiolate, the petiole up to 1 cm long, glandular, hispidulous, stipulate, the stipules persistent, borne on the petiole about 1.5 to 2 mm above its base, linear, up to 5 mm long, glandular and hispidulous; blades broadly ovate to suborbicular, the larger 6 cm long by 4.5 cm wide, cordate or subcordate at base, abruptly short-acuminate at apex, conspicuously dentate ( the teeth broad, extending to the middle of the blade or below ), ciliate, above sparsely but uniformly strigose ( the hairs all simple ), glabrate with age, beneath glandular, hispidulous on the veins and veinlets, densely bearded in the vein axils; lateral veins 2 to 5, straight, reaching the margin; peduncle up to 3.5 cm long, conspicuously glandular, bearing a few stellate hairs, these with numerous spreading branches; bracts at base of inlorescence conspicuous, up to 1.5 cm long, 2 mm broad at middle, narrowed at base, glandular and sparsely pubescent, the hairs both simple and stellate; cyme up to 5.7 cm wide and 3 cm long, twice compound, the primary rays 6 to 8, very densely glandular; bractlets of cyme linear, glandular, sparingly ciliate; calyx tube 2 to 2.5 mm long, cylindric, densely glandular; calyx lobes about 1 mm long, acute, ciliate with long simple hairs, glabrous on the back, eglandular; corolla 3.5 to 4 mm long, glabrous; stamens slightly exserted, the ilaments about 4 mm long; style glabrous; fruit much lattened, about I cm long, 8 mm wide, and 3 mm thick, leshy, the endocarp 3-sulcate on one face ( the central groove very slight, the lateral pronounced ) and lightly 2-sulcate on the other, with no ventral intrusion.
