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, 14-16.5 cm wide; peduncle 71.5 cm long; rachis 52.5 cm long; 43 first order branches, basal and middle first order branches with 18-25 second order branches (14.5-21 cm long), distal first order branches with 1-2 second order branches (6.5-10 cm long).
Inflorescences interfoliar, 3-4 per node, sharing a common, 3-4-chambered prophyll
, curving, becoming pendulous, branched to one order with appressed rachillae; prophyll
34-72 x 78.5 cm; peduncular bract ca.
(vegetative) innovation zone, stolons/runners with bracts, addorsed prophyll
This peculiar object, kolit sepootn, consists of the bag-shaped first bract (botanical term: prophyll
) borne on the inflorescence of the pinang palm (Areca catechu).
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
. Likewise the lemma, although clearly abaxial and bract-like, shares some similarities with an outer perianth whorl.
leuconeura (Gonzalez 3290), straight elongating shoot (2-0) showing also a non-pseudostipular prophyll
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).
In most taxa they bear a prophyll
and a variable number of leaves (Fig.
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.
Leaves filiform, 0.3-0.8 mm wide; culms obtusely trigonous to compressed-trigonous; 0-1 sterile scales at the base of the spikelet (excluding the prophyll
); anthers 1.7-2.8 mm long; achene 1.1-1.5 mm wide C.
In addition, axillary branches were divided into prophyll
(the first leaf of a lateral branch), internode, sheath, and inflorescence.
