8. Merremia crispatula, Prain Beng. PI. II. 730; var. anda- 

 manica, Prain. A large glabrous scandent herb. Leaves ovate-cor- 

 date, acuminate, margins entire or faintly undulate, glabrous on both 

 surfaces, 3 to 4 in. long, 2-5 to 4 in. wide ; petiole 1 to 1-5 in. long. 

 Floivers in axillary few-flowered cymes, peduncles 1*5 to 2 in. long, 

 pedicels -75 to 1"25 in. long, thickened upwards. Sepals orbicular, 

 •5 in. long, in fruit -75 in. long. Corolla campanulate, Hmb hardly 

 lobed, tube hirsute externally, yellow, 1-25 in. long. Capsule sub- 

 orbicular, -75 in. across. Seeds minutely velvety, margins somewhat 

 shaggy. Ipomcea petaloidea, var. anclamanica, Prain Journ. As. Soc. 

 Beng. LXIII. 2, 110. 



Andamans : S. Andaman, common. 



This is in all probability specifically distinct from Merremia crispatula {Ipomcea 

 petaloidea, Choisy), but it seems preferable to treat it for the moment as a variety of that 

 species and not as a new species, because of its remarkable resemblance to Merremia 

 Riedeliana, HaUier f. (Ipomcza Riedeliana, Oliv.), and Merremia mammosa, Hallier f. 

 {Ipomcea mammosa, Choisy,). From the former, as described and figured by Oliver, 

 this differs in having a4-celled ovary with 1 ovule in each cell, whereas M. Riedeliana 

 has a 2-celled ovary with 4, sometimes 5, ovules in each cell. From M. mammosa, as 

 figured by Eumphius, this differs in having obtuse calyx-lobes and a shaggy corolla ; 

 Rumphius' figure shows the sepals acute and the corolla glabrous. This plant appears 

 to be the same thing as Convolvulus platypeUis, Span., from Timor, and if it proves to 

 be distinct alike from M. Riedeliana and M. mammosa, which last is cited by Dr. Hallier 

 as an Andaman plant, though we have no authentic example of 31. mammosa from 

 the Andamans at Calcutta, the name it should bear will be 2Ierremia platypeltis. 



12. Opbrculina, Manso. 



Large herbaceoiis climbers ; stems, peduncles and petioles usually 

 winged. Leaves large, entire or lobed, rarely peltate. Floioers large, 

 showy, axillary, solitary or often in few-flowered cymes. Sepals 5, large, 

 ovoid, glabrous, accrescent in fruit and ultimately irregularly spHtting 

 from the tip. Corolla infundibuliform, rarely campanulate ; tube with 

 5 vertical smooth bands. Stamens 5 ; filaments filiform ; anthers large, 

 at length contorted ; pollen never spinulose. Ovary 2-celled, glabrous ; 

 ovules 4 ; style filiform ; stigma 2-globose. Fruit a capsule, not
