Valley, flowering 1868, Hillebrand, without number, in herb. Berlin; 
Wawra no. 1746 (flowering), in herb. Vienna (four sheets); Pauoa 
Valley, flowering, Nov. 4, 1908, Rock no. 704; same locality, flowering 
Oct. 29, 1909, Rock no. 10346. 
In the Berlin herbarium with the Hillebrand material, is a sheet 
labeled C. grandiflora, collected in the Malay peninsula, State of 
Pahang in 1909, no. 13673; this plant does not belong to our C. grandi- 
flora Gaud. 
The calyx and flowers of that specimen are silky tomentose, and 
in other respects it does not agree with our plant. The Meyen speci- 
men is labeled C. Rucriana, while C. B. Clarke cites it in his mono- 
graph as C. Ruckiana. 
A very distinct species common in the valleys back of Honolulu, a 
branching shrub with large white attractive flowers; occurs only at 
lower elevations of 500-1,000 feet, usually in dense shade along water 
courses.

It seems that this species has only been collected by Mann, for 
the writer found no material of it in any of the collections, neither in 
those of Wawra nor Hillebrand. C. B. Clarke in his monograph says 
also ''species non visa." 
The writer is not acquainted with the species but with the variety 
petiolaris Wawra.
