5-8-denticulate at their subtruncate apices, but sometimes irregularly 
divided into many subulate teeth, dark purple-brown ; inner corona- 
lobes } lin. long, deltoid, acute, closely incumbent upon the backs 
of the anthers and slightly exceeding them, broadly connected at 
the base to the outer corona, dark purple-brown ; follicles (imma- 
ture) erect, slightly diverging, 3-34 in. long, 24 lin. thick, narrowly 
fusiform, tapering to an acute apex, smooth, glabrous, dull greyish- 
green, thickly marked with linear spots and lines of purple-brown.

Described from a living plant which flowered at Kew, Aug. 1907. The inner 
surface of the corolla is exceedingly beautiful when highly magnified, and unlike 
anything I have seen in any other plant. 
XLIV. CARALLUMA, R. Br. 
Calyx 5-partite. Corolla 5-lobed, with a small or very rarely 
large campanulate or saucer-shaped tube, or rarely without a distinct 
tube and the united part nearly flat and disk-like ; lobes free at the 
tips, very spreading or ascending, ovate to linear. Corona usually 
distinctly 2-seriate ; outer series of 5 distinct entire or bifid lobes or 
united into an entire or 5—15-toothed cup ; inner series of 5 filiform, 
subulate, linear, oblong, subquadrate or hemispheric lobes, shorter 
than to much longer than the anthers and often dorsally connected 
to the outer series; or sometimes both series combined so as to 
falsely appear l-seriate. Stamens with their filaments connate into 
a tube around the ovary and adnate to the dilated style-apex ; 
anthers free, ascending or inflexed upon the style-apex. Pollen-masses 
solitary in each anther-cell, ascending or subhorizontal, pellucid just 
under the apex or within the inner margin, attached in pairs by 
short slender caudicles to the pollen-carriers or to wing-like expansions 
of them, 
Dwarf succulent leafless herbs, with stout 4-6- (very rarely 3-) angled stems 
and branches, toothed or toothless along the angles. Flowers variable, usually in 
fascicles, rarely solitary, near or at the base, apex, or along the grooves between 
the angles, in a few species racemose along the attenuated terminal part of the 
stems. 
Distris. Species about 80, the others distributed in Tropical and North 
Africa, South Europe, Socotra, and through Arabia to India. 
Stems obscurely 6-angled or with obscurely 6-seriate 
tubercles (? tessellately 6-angled); pedicels 4-5 lin. 
long; corolla densely pilose on the inner face, 
_ green... Reds <ilead je aes «+ ose (20) chlorantha. 
Stems without distinct teeth, but sometimes somewhat 
crenate along their 4 very obtuse angles: 
Plant 2-23 in. high ; ties 1-3 in. long, erect from 
near the base of the decumbent stems ... .. (23) aperta. 
Plant 9-12 in. high, bushily branched, flowering near 
or at the ti of the Bechara pedicels about 1
