flowered, with ascending branches; peduncles li^-G lin. long, glabrous; 

 bracts h lin. long, ovate, subobtuse, minutely ciliate ; pedicels 2-3-J- 

 lin. long, glabrous. Sepals elliptic-ovate, obtuse or subacute, minutely 

 ciliate. Corolla 2-2-| lin. in diam., .alabrous ; tube }^ lin. long; lobes 

 1 J 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.

Calyx 5-partite. Corolla deeply r)-lid ; 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. PoUen-maf^ses very minute, ascending, apparently 2 to each of 

 the pale, rather soft, quadrate pollen-carriers, but each apparently 

 single mass usually consists of 2 subcx)nnate 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. PI. ii. 771. 



Species several, mostly natives of Tropical Asia and the Malay Arcbii^elago. 

 Dr. Schumann has united Torocarpus 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 otlier hand the dorsally 

 flattened coronal-lobes, combined pollen-masses, usually larger flowers, and rather 

 different habit oiToxocarpus, appear to me suflScient grounds for retaining it as dis- 

 tinct from Secamone. In its pollen-masses Toxocarpns 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 Marsdeniece, with which these plants have no 

 affinity, their whole type of structure being in entire agreement with the Indian 

 species of Toxocarpus. Dr. Schumann makes no mention of the dorsally flattened 

 coronal-lobes or of the structure of the pollen-masses.
