certainly the same as the Chinese one. Whether or not Cyclodon distans 
Gi'ifF., is the same or not has no bearing on the case, as it was not published 
until 1851. 
LOBELIA L. 
Lobelia bialata sp. nov. § Isolobus. 
Planta parva, glabra, erecta vel suberecta, circiter 10 cm alta, 
ramosa; caulibus tenuiter bialatis; foliis elliptico-ovatis, acum- 
inatis, basi angustatis, sessilibus vel subsessilibus, usque ad 2 
cm longis et 1 cm latis, superioribus minoribus, margine distincte 
serratis; pedunculis axillaribus, solitariis, folia subaequantibus ; 
floribus roseis, circiter 5 mm longis. 
A small, erect or suberect, branched, glabrous, annual herb 
about 10 cm high, the lower parts of the stem sometimes decum- 
bent but scarcely rooting at the nodes. Stems slender, narrowly 
2-winged. Leaves thin, elliptic-ovate, up to 2 cm long and 1 cm 
wide, the upper ones smaller, margins rather distantly and dis- 
tinctly sharply serrate, base narrowed, acute, sessile or subsessile, 
apex shortly acuminate or acute. Pedicels axillary, slender, 
solitary, about as long as the leaves, 1-flowered. Calyx-tube 
broadly ovoid, nearly 2 mm long and thick, green, the teeth 5, 
linear, erect, 2 to 2.5 mm long. Corolla about 4 mm long, pink, 
the lower lip violet, subequally 3-lobed, the lobes oblong-ovate, 
pointed, about 1.5 mm long, the upper lip with two linear- 
lanceolate, acuminate, 1.5 mm long teeth. Filaments united; 
3 fertile anthers glabrous, two sterile ones ciliate at the apex. 
Stigma slightly cleft. Fruit somewhat ovoid, narrowed at both 
base and apex, half-superior, about 3 mm long, the part above the 
calyx 2-valved. Seeds numerous, brown, ellipsoid, smooth, about 
0.3 mm long.

This species is closely allied to Lobelia radicans Thunb., but differs in a 
number of characters, in its broader, differently-shaped leaves, its stems 
not prostrate and rooting, its smaller flowers, and its two lower filaments 
glabrous, not hairy. It is even more distinct from Lobelia filiformis Lam., 
both as originally described by Lamarck from the Isle of France material, 
and as later figured and described by Cavanilles from Luzon material.
