prophyll การใช้

• Pistillate and staminate members are indistinguishable without opening the protective prophyll.
• This structure is called the perigynium or utricle, a modified prophyll.
• The prophyll may or may nor be armed and eventually develops a longitudinal split, exposing the flowers.
• The prophyll is large, splitting and becoming tattered, and armed with pseudo-whorls of black spines.
• The peduncle is long and the prophyll short and tubular, disintegrating into a fibrous mass at the base.
• There are four to five peduncular bracts, longer than the prophyll, with the distalmost exceeding the peduncle.
• The short peduncle is waxy and covered in hairs, the enclosing prophyll is similarly covered, two keeled and beaked.
• Prophylls 5, lanceolate, the margins spiny and bristly, about 1 cm ( 0.3 inches ) long.
• Plants are monoecious : with inflorescences up to 1.2 m long, erect among the leaves; prophylls and peduncles are not known.
• In pistillate members it is branched to two orders, staminate to three; in both, a boat shaped, beak-ended prophyll encloses it.
• In some older botanical writing, the term " stipule " was used more generally to refer to any small leaves or leaf-parts, notably prophylls.
• The peduncle is short, the prophyll is tubular and two-keeled, peduncular bracts usually absent, and the rachis is much longer than the peduncle.
• A "'prophyll "'is a leaf-like structure, such as a bracteole, subtending ( extending under ) a single flower or peduncle.
• The prophyll is two keeled, short and fibrous, the peduncular bract is longer, tubular, and forms a hairy net around the flowers with two bracts borne below each.
• Covered in scales, the peduncle is short and thick, the prophyll is tubular, beaked and tomentose, and the long rachis bears numerous short rachillae which are often Z-shaped.
• Because it has a prophyll at the base of the pedicel, it therefore would fall within section " Crocus ", although its exact relationship to the rest of the subgenus remains unclear.
• This recently described species is Malagasy vernacular name used by the Betsimisaraka people for the " Dypsis " palm species ( mostly for " Dypsis lastelliana " ), whose leaves and prophylls are the habitat for this frog.
• Instead, the inflorescences push through the persistent, disintegrating, subtending leaf sheaths : they are spreading, with peduncles 5 mm long, 9 mm wide; " prophylls " ( the lowest tract of the inflorescence ) are 90-140 mm long, persistent and erect, splitting abaxially.
• In 1992, N . G . Marchant and Allen Lowrie published the formal description of " D . marchantii " subsp . " prophylla ", a subspecies that is distinguished by its white flowers, smaller height, and numerous bracts ( prophylls ) on the lower part of the stem.
• Interfoliar, branched to 2 ( 3 in a few cases ) orders, with the basal part within the closed sheath, the prophyll hidden and the peduncular bract spreading from the top of the sheath; peduncle 68 123 cm . long, distally 9 x 5 cm . in diam ., green, glabrous, curved outside the sheath; prophyll c . 91 cm ., borne at 32 cm . above the base of the peduncle, 11.5 cm . wide, narrowly 2-winged; peduncular bract deciduous, about 80 cm ., beaked ( about 5 cm . ) and closed distally, pale waxy grey, inserted about 48 cm . from the base of the peduncle; open peduncular bract 14 x 7 cm .; rachis 84 102 cm ., with 23-24 branched and 14-17 unbranched first order branches, in a few cases some of the proximal branches branched twice more, but not more than 3 in the entire inflorescence; all axes green with white bloom; first order branches proximally 2-3 x 0.5 1 cm .; rachillae 14 32 cm ., 3 4 mm . in diam ., with flattish base and distant to rather dense triads, hardly sunken in slight pits with entire, obtuse or acute bracts . "'Staminate flowers "'with sepals 2.2-2.5 x 1.6-2.2 mm ., keeled, gibbous at the base, broadly ovate, obtuse, the margins membranous; petals connate for 0.2-0.5 mm ., the free lobes 2.8-3 x 2.8-3.2 mm ., ovate or elliptic, acute, sometimes with hooded apex; stamens 6, uniseriate, the filaments connate for 0.2-0.5 mm ., 2.8-3.2 mm . long, anthers 2.1-2.3 x 1 mm .; pistillode 2.2-2.3 mm ., columnar, 0.8 1 mm . in diam.
