10.5 cm; base subcordate to oblique; petiolar
portion 8-10 cm long; penducle of the inflorescence 18-25 cm long; bracteoles 5-nerved ...
--Mandible with scattered isolated punctures that do not unite, completely smooth and glossy between punctures with little evidence of striae or rugulae, mandible shorter than head length (MI 48.27-56.45); anterior medial raised area of clypeus with or without sharp carina or lacking carina; posterior border of petiolar
node with little evidence of depression; fourth abdominal segment (second gastral segment) slightly roughened or sculptured ...
Morphological traits which showed variation among the progenies were determined as the anthocyanin intensity on shoot tip, young leaf upper surface color, mature leaf form, mature leaf blade shape, shape of petiolar
sinus, and petiolar
sinus width on mature leaf, petiole color and cane color.
How tall is an unanswered question because biomechanical analysis is not possible and petiolar
distribution is not necessarily related to the length of the stem (see variations illustrated by Wnuk and Pfefferkorn 1984, fig.
Members of the genus can usually be recognized by the following combination of character states: 2-segmented petiole; 2-segmented antennal club; propodeum lacking spines or angles; petiolar
node well developed; head and body shining, sculpture restricted to setigerous punctures and localized striae; clypeus longitudinally carinate, with a median, apical marginal seta.
faginea, but differs by the number of buds on branch apices, stipular shape, petiolar
surface, inflorescence length and position, stylar branching, and fruit peduncle and spines.
Observations on petiolar
branching and foliage of an American Botryopteris.
Morphogenic response could have been attributed to the juvenility of the petiolar
(rachis) cells rather than of distal segments.
Description.--Male (from Nam Nao National Park, Thailand):: Total body length 4,2 mm (including lengthened/outdrawn petiolar
The number of wide vessels in petiolar
vascular bundles of palms: an anatomical feature of systematic significance.
Creating the conditions for a successful microbial balance starts in the vineyard, with petiolar
nitrogen measurements at bloom.
Petiole with peduncle shorter or as long as petiolar
node, node with rounded apex; petiolar
spiracle near anterior side of petiole.
