East Maui; and of C. Grayana three varieties, var. linearifolia from West 
Maui, var. lanaiensis from the island of Lanai, and var. nervosa from Mt. 
Puukukui, also West Maui. The island of Kauai has furnished this section 
with one of the most distinct species with no immediate or close relatives or 
varieties of any sort. Molokai has furnished two species: one, C. halawensis, 
is related to C. Grayana but is certainly distinct enough to be classed as a 
species; C. Conradtii belongs in a class with C lysiosepala, but has the ap- 
pearance of C. paludosa or C. longifolia, the specific limits here not being as 
well defined as in the case of the species from Kauai. Hawaii furnishes one 
species, C. kohalaCj which must be classed with the present section, but is in 
habit similar to the Crotonocalyces. It is the only representative of this 
section on Hawaii. We see from the. distribution of the species of this 
section that C. Grayana has taken possession of the central group of islands, 
predominating on the western end of Maui where the species and most of 
its varieties occur. The remaining varieties of C. Grayana are to be found 
in the immediate neighborhood of West Maui, as for example diagonally 
across only a few miles distant, on the western end of Molokai (var. Fauriei), 
and immediately across to the south of West Maui on the island of Lanai, 
only a few miles distant (var. lanaiensis). Its closest relatives are found 
also on the western end of Molokai in Halawa Valley (C. halawensis), and 
on the more distant summit range of Pelekunu-Waikolu in the central part 
of Molokai (C. procera). Its nearest relatives on Oahu are probably C. 
Oliveri (C. Hillebrandi Oliver) and the specifically more remote C. Les- 
soniana. Most of the species of Cyrtandra found on Hawaii belong to the 
group of C. platyphylla; there are, however, two other species : C. Menziesii, 
belonging to Section Chaetocalyces, and one other, belonging to Section 
Microcalyces. Cyrtandra lysiosepala has a distribution similar to that of 
C. Grayana, being restricted with its varieties to the two central islands, 
Maui and Molokai. Variety pilosa from Maui seems to bring C. lysiosepala 
close to C. waiolani from Oahu. 
Cyrtandra Lessoniana Gaud. Voy. Uranie 447, tab. 54. 1826 
A shrub 1.75-3 n^- high, branches terete to subquadrangular, young 
branches and inflorescence fulvo-silky-tomentose; leaves opposite, elliptical- 
oblong to obovate-oblong, acute at both ends, minutely denticulate, thin to 
thick-chartaceous, glabrate or sparsely pubescent above, silky-tomentose 
underneath with yellowish-brown hair, especially along the midrib, veins, 
and nerves, 6-21 cm. long, 2-5 cm. wide, on petioles of 1-3.5 cm.; flowers 
usually single in the axils of the upper leaves, drooping, rarely two, on a 
peduncle of 1-2.5 cm.; pedicels 1-2 cm.; bracts oblong to linear-lanceolate, 
0.6-1 cm. long; calyx thin, whitish, glabrate or hirtulose, divided nearly to 
the base into broadly ovate acute lobes, these angular-valvate in the bud, 
open and quite reflexed with fruit ; corolla exceeding the calyx often by one 
third, sometimes as long as the calyx, 20-25 mm. long, straight- tubular, 
ampliate above, with short obtuse lobes, the entire corolla covered with 
long whitish silky hair, glabrous inside or puberulous; ovary ovoid, glabrous,
