Cyrtandra laxiflora Mann is certainly a distinct species and, as Mann 
states, comes close to C. Macraei but in flowers only. 
To C. laxiflora Mann must be referred as a special variety Hillebrand 's 
var. grandifolia of C. triflora Hillebr. not Gaud. This latter plant is 
certainly much more closely related to C. laxiflora than to C. polyantha 
C. B. Clarke (C. triflora Hillebr.). Here belongs also a new variety from 
Kaliuwaa Valley, C. laxiflora rhyzantha, which see. 
Cyrtandra laxiflora rhizantha Rock n. var. 
A shrub with few ascending branches; leaves 15-20 cm. long, 6.5-8 cm. 
wide on petioles of 4-10 cm., sharply dentate, otherwise as in Cyrtandra 
laxiflora var. grandifolia; inflorescence on the stem near the ground and on 
exposed roots, a twice to thrice dichotomous cyme, the peduncle of varying 
length, 1.5-3 cm. long; bracts 8 mm.; ultimate pedicels of varying length, 
villous; calyx and corolla as in var. grandifolia. 
Oahu: Koolau Mts., Punaluu, flowering October 31, 1914, Rock no. 
13086 in herb. College of Hawaii. 
This plant differs little from C. laxiflora var. grandifolia, but mainly in 
the smaller leaves, and open and lax thrice-dichotomously branching cyme. 
The inflorescence is borne on the lower portions of the stem and on exposed 
roots, hence the name. 
Cyrtandra laxiflora grandifolia Rock n. comb. 
Cyrtandra triflora Hillebr. var. grandifolia Hillebr. Fl. Haw. Isl. 332. 1888. 
Branches glabrous, apices hirtellous to villous; leaves large, ovate to 
suborbiculate, 15-24 cm. long, 6.5-14 cm. wide, acuminate at the apex, 
rounded at the base or uneven-sided, hispidulous above, pubescent below, 
especially on the stout midrib and nerves; petioles 3-5.5 cm.; cymes large, 
open, branching; bracts 7 mm., acute; pedicels filiform, villous; calyx as in 
C. laxiflora, more deeply divided, the lobes linear-acute, 8 mm.; corolla 
12-14 mm., the tube narrow-cylindrical, ampliate at tke throat, hirsute 
especially in the upper third; ovary elliptical, sessile and rounded at the 
base, long acuminate at the apex, puberulous; fruit twice as long as the 
calyx, elliptical-acuminate, puberulous.
