CYRTANDREAE HAWAIIENSES, SECTIONS SCHIZOCALYCES 
HILLEBR. AND CHAETOCALYCES HILLEBR. 
Joseph F. Rock 
The present paper is the third of a series deahng with the Hawaiian 
members of the genus Cyrtandra. The two previous papers were pubHshed 
in this Journal (4 : 604-623 ; 5 : 259-277) . 
Section Three: Schizocalyces Hillebr. Fl. Haw. Isl. 325. 1888 
Calyx large, split to near the base into more or less equal broadly ovate 
to linear-lanceofate lobes. Flowers either single or three rarely more in a 
corymbose cyme (C Grayana) or umbel (C. umhracculiflora) . Leaves 
linear, lanceolate to obovate-oblong or broadly ovate. Tomentum fulvous 
or deep ferruginous. 
Hillebrand classed under Section Schizocalyces the following species: 
C. macrocalyx, C. lysiosepala, C. Grayana, C. procera, C. Lessoniana, C. 
biserrata, C. kauaiensis and C. Hillehrandi; of C. lysiosepala he enumerates 
three varieties: /3, 7 pilosa, and 6; of C. Grayana sl var. latifolia; of C. 
Lessoniana a variety /3, 7 angustifolia, and 8 pachyphylla. Clarke de- 
scribed a new species as C. Grayi, which had to be referred to C. lysio- 
sepala where it is retained as a variety Grayi in this paper. Hector 
Leveille described as new two species C. Fauriei and C. kamoloensis , 
which come under the section treated in this paper. The former is 
identical with Hillebrand 's variety 5, of Cyrtandra lysiosepala (Fl. Haw. 
Isl. 330. 1888); it is not specifically distinct and is therefore retained 
with the name Fauriei as a variety of C. lysiosepala; the second species 
is identical with Cyrtandra Grayana and is consequently reduced to syn- 
onymy. Hillebrand 's varieties of C. Lessoniana have been incorporated 
with the species because the numerous intermediates do not permit of their 
being retained as distinct varieties. Hillebrand's var. j8 of C. lysiosepala 
was given the name latifolia. The writer has added four new species, 
C. halawensis, C. kohalae, C. Conradtii, and C. umhracculiflora, which are 
here described for the first time. The first and third are peculiar to the 
island of Molokai, the second to the oldest portion of the island of Hawaii, 
and the fourth to the island of Kauai. To the existing varieties he has 
added also four new ones: of C. lysiosepala a variety haleakalensis from
