bracts } lin. long, ovate, subobtuse, minutely ciliate; pedicels 2-3} 
lin. long, glabrous. Sepals elliptic-ovate, obtuse or subacute, minutely 
ciliate. Corolla 2-2} lin. in diam., glabrous; tube } lin. long; lobes 
14 lin, long, oblong, obtuse. Coronal-lobes compressed, falcate, reaching 
nearly to the top of the staminal-column. Style shortly exserted beyond 
the anthers; apical part cylindric, not at all dilated at the top.

12. TOXOCARPUS, Wight and Arn.; Benth. et Hook. f. Gen. 
FE ii. 746. 
Calyx 5-partite. Corolla deeply 5-fid; tube very short, campanulate 
or shortly turbinate-campanulate; lobes spreading, longer than the 
tube, overlapping to the right and straight or twisted to the left or to 
the right in bud, and having two thickened ridges or bosses at their 
base. Corona of 5 dorsally flattened lobes arising from the back of the 
staminal filaments, alternating with the corolla-lobes. Stamens arising 
from the bottom of the corolla; filaments adnate to the style, but not 
connate with each other or only at the very base; anthers small, erect 
or conniving around the style, with a minutely fimbriate submembranous 
border. Pollen-masses very minute, ascending, apparently 2 to each of 
the pale, rather soft, quadrate pollen-carriers, but each apparently 
single mass usually consists of 2 subconnate often separable (or 
occasionally perfectly consolidated) masses. Style produced beyond the 
anthers into a beak.—Twiners with opposite leaves and axillary cymes 
or racemes of small or moderate sized flowers.— Rhynchostigma, Benth. 
in Benth. et Hook. f. Gen. Pl. ii. 771. 
Species several, mostly natives of Tropical Asia and the Malay Archipelago. 
Dr. Schumann has united Toxocarpus with Secamone, whilst he maintains 
Rhynchostigma as distinct. But in this I cannot agree with him, for Rhyn- 
chostigma and Toxocarpus are certainly identical. On the other hand the dorsally 
flattened coronal-lobes, combined pollen-masses, usually larger flowers, and rather 
different habit of Toxocarpus, appear to me sufficient grounds for retaining it as dis- 
tinct from Secamone. In its pollen-masses Tovocarpus forms a connecting link 
between Secamone with its 4 very distinct pollen-masses and those genera having 
but 2 pollen-masses, For in Toxocarpus the 2 pollen-masses contained in each lobe 
of the anther are (at least in the dried state) more or less united into one body, the 
double nature of which (when evident), is only indicated by a faint suture, although 
the two parts can sometimes be separated by the dissecting needle. This, being 
overlooked by Bentham, caused him to found a genus on the African species; 
which he placed in the tribe of Marsdeniew, with which these plants have no 
affinity, their whole type of structure being in entire agreement with the Indian 
species of Torocarpus. Dr. Schumann makes no mention of the dorsally flattened 
coronal-lobes or of the structure of the pollen-masses,
