CYRTANDREAE HAWAIIENSES 
265 
Cyrtandra cordifolia gynoglabra Rock n. var. 
Habit of species; leaves ovate to orbicular in outline, acute at the 
apex, somewhat oblique and cordate at the base, dark green above, 
hirsute, dirty brown beneath; peduncles shorter, 3.5 cm. long; calyx 
as in the species, the lobes very broad-triangular; corolla hirsute; 
ovary glabrous, as is the articulate style. 
Maui: Eastern part, southern slopes of Mount Haleakala in gulch 
near Kaupo, 5,000 feet, flowering Nov., 1910, Rock no. 8687 in herb.

This plant differs from the species occurring on the island of Oahu 
at a much lower elevation (1,000-1,500 feet) mainly in the glabrous 
ovary; the calyx lobes are, as in the species, deltoid to broadly triangu- 
lar-ovate, and the plant agrees in all other respects with C. cordifolia. 
It differs from C. begoniaefolia in the cordate leaves and broad calyx 
lobes, while the lobes of C. begoniaefolia are erect, lanceolate, acute. 
Hillebrand does not state whether the ovary is glabrous or not. 
Cyrtandra begoniaefolia occurs, or rather is supposed to occur, at 
Ulupalakua not far from where C. cordifolia gynoglabra grows, but the 
writer has been unable to relocate it.
