Artocarpus longifolius

Description

Tree up to 20 m tall, of intermittent growth, with terminal (and lateral?) buds, deciduous (?). Leaves distichous; stipules lateral, 0.3-0.5(-1) cm long, brownish puberulous, caducous (or subpersistent). stamen c. 0.8 mm long, anther 0.1-0.2 mm long; fruit not seen.

Morphology

1The species can be recognised by the short and thick petiole with exfoliating epidermis. 2Jarrett (1960) assumed that subglabrous specimens represented (sub)juvenile material. However, two such specimens are fertile and a specimen bearing a pistillate inflorescence has a much shorter peduncle (c. 0.3 cm long as opposed to 2-6 cm long in ± densely hairy specimens). The differences in indumentum possibly correlate with the length of the peduncles of the pistillate inflorescences and suggest distinction of subspecies, or closely related species. More material is needed to sort out the status of these two morphological entities which are sympatric and apparently have a similar ecology.
