Each lateral spikelet emerges from the axillary bud of a bract, bearing a prophyll
and a varying number of glumes arranged on an open axis (rachilla); some or all of these glumes develop an axillary flower, so some taxa have empty glumes, while in other taxa each glume carries a flower.
Two bud developmental stages (developing and mature) were characterized by their prophyll
Staminate inflorescence with prophyll
14 cm long, 12 cm wide; bracts 7, carinate and more or less rostrate, light-brown, 24-136 cm long, 14-16.
Inflorescences 90-123 cm long, interfoliar or infrafoliar when old; prophyll
35 cm long, 1.
The evolutionary history of the palea is more controversial; although it is in the position of an outer perianth whorl, it is adaxial and in many grasses looks very much like a prophyll
In a group of Neotropical species, the prophyll
of each renewal shoot develops into a sessile, round, clasping leaf called a pseudostipule (Duchartre, 1854b; Gonzalez, 1990).
This generally takes place as the second leaf is appearing on the primary tiller, and this apparent early appearance is due to the production of the prophyll
, or rudimentary leaf (Neuteboom and Lantinga, 1989) which is usually not visible at early stages of growth in creeping bentgrass (Cattani, 2000).
There have existed a long-standing disagreement in the use of the terms achene and nutlet to refer Carex's fruits, and perigynium and utricle to refer the enclosing prophyll
(Global Carex Group, 2015).
Inflorescence erect; prophyll
55 cm long, densely brown setose; peduncular bract to 95 cm long, proximal part covered with brown, 2-4 mm long bristles, these usually not persistent, and grey floccose, flattened, black spines, distal part with flattened, black, up to 5 cm long spines; peduncle to 130 cm long, 3,2 x 4,1 cm in cross section, proximal part tomentose, distal part spiny; rachis 23-38 cm long; rachillae many, to 14 cm long, proximal part 1-5 cm long, glabrous, distal part bearing the pistillate flowers, 3,5-9 cm long, covered with minute, clavate, hyaline hairs, only one pistillate flower inserted 0,2-1,5 cm from the rachis.
In addition, axillary branches were divided into prophyll
(the first leaf of a lateral branch), internode, sheath, and inflorescence.
paraclade consists of a short hypopodium, a prophyll
, an epipodium and a
Inflorescence branching to one order, interfoliar, erect, arching or pendulous, protogynous; peduncle usually elongated, circular to oval in cross section, densely covered in indument, often heavily armed with spines; prophyll
short, bicarinate, fibrous, unarmed or armed with small spines or bristles, hidden in the leaf bases; peduncular bract much exceeding the prophyll
, spindle-shaped, often rostrate, splitting longitudinally along the abaxial face, persistent or eroding, usually densely tomentose, heavily armed with spines or unarmed; rachis shorter than the peduncle bearing spirally arranged rachillae, each sustented by a narrow triangular bract; rachillae ca.
