  • Description

    Species Description - Secondary stems 8-50 cm long, simple to ± regularly pinnate, often glossy, yellow, yellow-green, or yellow-brown. Leaves loosely imbricate to wide-spreading when dry, wide-spreading to subsquarrose when moist, fragile or not (the tips of older leaves sometimes missing), 3-6 mm long, broadly ovate and plicate at base, gradually tapered to a narrowly lanceolate acumen; upper cells porose, short, rhombic to somewhat elliptic, up to 17 µm long and about 9 µm wide, those near the costa at base linear, up to 50 Jim long and 9 µm wide; alar cells confined to the basal angles, quadrate, frequently with cruciform lumina. Leaves of tertiary branches narrower at base, less subulate. Setae 3 mm long; capsules 2.5-2.8 mm long, ovoid.

    At times difficult to distinguish from P. densus, these plants are shinier, softer, and more commonly pinnatebranched, with a more pronounced heterophylly between secondary and tertiary branches and less fragile leaf tips.

    Prionodon dichotomus Hampe has been used to include this species in synonymy (Robinson, 1964b), but Griffin (1973) has presented a case for distinguishing the two species and retaining both names in use.

    The name Prionodon lozanoi Card., used by Brotherus (1924-1925) and Bartram (1928b), seems to have resulted from a slip of the pen for P. solorzanoi Card, (listed in synonymy above).
