the petioles. Pedicels 1 to 8 lines long. Calyx-segments broad, obtuse, the 

 margins more or less scarious, about 1^ line long. Corolla pubescent outside, 

 the broad tube as long as the calyx, thickened inside at the throat into a 

 prominent glabrous ring ; lobes spreading, obtuse, rather longer than the tube. 

 Corona-segments vertically adnate, laterally compressed, with 2 prominent angles 

 or keels on the back, more or less confluent at the base with those of the 

 adjoining segments, tapering at the top into free incurved points as long as or 

 rather longer than the anthers. Pollen-masses linear-oblong. Stigma thick, 

 obtuse or shortly 2-lobed, not exceeding the anthers. Fruit not seen. — Dene, in 

 DC. Prod. viii. 614.

In foliage this plant resembles Parsonsia velutina, but the flowers are very different. — Benth. 



6. JUL. araujacea (Araujia-like), F. v. M. Fragm. vi. 135 ; Benth. Fl. Austr. 

 iv. 339. A large twiner, the branches and foliage sprinkled with appressed 

 hairs. Leaves on rather long petioles, cordate-ovate, shortly acuminate, mem- 

 branous, 4 to 5in. long. Flowers large, in dense simple umbels, on lateral 

 peduncles shorter than the petioles, the pedicels, bracts,- and calyx shortly 

 pubescent. Calyx-segments nearly orbicular, very obtuse, 3 lines long. Corolla 

 about ^in. long, the tube very broad, slightly contracted at the throat, the lobes 

 rather longer, bearded inside with long hairs up the centre and round the base. 

 Corona-segments broadly-oblong, peltately adnate, almost cartilaginous, the 



' margins free, the upper end exceeding the anthers and abruptly contracted into a 

 short point. Pollen-masses linear-oblong. Stigma with a narrow conical beak 

 not exceeding the corona. 

 Hab.: Bockingham Bay, Dallachy. 



7. M. rostrata (stigma^beaked). R. Br. Prod. 461 ; Benth. Fl. Austr. iv. 

 339. A rather stout twiner, either glabrous or the young shoots and inflorescence 

 or the whole plant tomentose-pubescent. Leaves on rather long petioles, ovate 

 to almost orbicular, shortly and obtusely but usually abruptly acuminate, not 

 cordate or very slightly so when very broad. Flowers sweet-scented, of a 

 greenish-yellow or nearly white, numerous, in simple dense globular umbels, on 

 interpetiolar peduncles shorter than the petioles. Pedicels 2 to 8 lines long. 

 Calyx-segments broad, obtuse, about 1 line long. Corolla glabrous outside, the 

 broad tube not contracted at the throat, nearly as long as the calyx, glabrous 

 inside ; lobes rather longer, spreading, obtuse, very shortly bearded below the 

 middle. Corona-segments with an adnate, scarcely prominent base, the free 

 part erect, incurved, nearly as long as or rarely longer than the anthers. Stigma 

 produced into a flexuose beak, already as long as the corolla before it opens. 

 Pollen-masses oblong. Follicles broad, acuminate, not above 2in. long. — Dene, 

 in DC. Prod. viii. 616.

8. fit. Praseri (after Chas. Fraser), Benth. Fl. Austr. iv. 839. A rather 

 slender twiner, quite glabrous. Leaves shortly petiolate, lanceolate, acute, 

 rounded at the base, 2 to 8in. long. Umbels simple and solitary, rather dense, 

 on interpetiolar peduncles of ^ to lin. Pedicels 2 to 3 lines long. Calyx- 

 segments very broadly ovate, very obtuse, about 1 line long. Corolla-tube broad, 

 as long as the calyx, slightly contracted at the throat, which is closed by a dense 

 ring of long inflexed hairs, the tube also slightly hairy inside ; lobes ovate, 

 obtuse, shorter than the tube. Corona-segments with the adnate part scarcely 

 conspicuous, the free erect part lanceolate, acute, about as long as the anthers, 

 Stigma rostrate as in 2W. rostrata. Fruit not seen,
