Hawaii: In the forests of Paauhau no. 2, near waterfalls between 
the crevices of huge boulders, northern slope of Mauna Kea, elevation

This interesting species belongs to the group with C. cordifolia 
rather than C. platyphylla on account of the triangular, reflexed 
calycine lobes. It differs from the latter in the subglabrous ovary, 
smaller calyx and straight cylindrical corolla, the short peduncle and 
oblique (not cordate) leaves. The name tintinnahula refers to the 
bell-shaped calyx.

There is only one sheet of this species in the Berlin Herbarium 
(ex coll. Hillebr.). It was originally labeled by Hillebrand Cyrtandra 
triflora Gaud. var. jS arguta folia unequilateralibus.'' The place known 
as Ulupalakua on East Maui must have been more or less covered 
with forest in Dr. Hillebrand's days. Today there is nothing but
