TILIACE^E. 

 Brownlowia riedelii, n. sp. 



BroivnlowicB elates affinis, differt foliis cordata-ovatis crassioribus, subtus minute lepi-* 

 dotis, supra nitidis, basi 5-nervosis, petiolis longioribus, floribus duplo minoribus, 



Wetter. — This species is readily distinguished from its nearest ally by the characters 

 given. Brownlowia elata has rotundate leaves, seven-nerved at the base, clothed with 

 very short pale brown hairs beneath, and the upper surface much less polished ; and the 

 flowers, with a whitish calyx, are at least double the size of this species. In floral structure 

 there is no essential difference. The fruit of Brownlowia riedelii is unknown. Alto- 

 gether four species are described, and the genus is restricted to India and the Archipelago. 



In the Flora of British India, Brownloivia peltata, Benth. (Journ. Linn. Soc. Lond. 

 v. Suppl., p. 56), is confounded by Masters with Brownloivia elata. The former was origi- 

 nally described from Bornean specimens, but it is also found in Mergui and other parts of 

 the Malayan Peninsula. It is easily recognised by its peltate leaves on very long petioles. 



Triumfetta rhomboidea, Jacq. 



Triumfetta rhomboidea, Jacq. ; Hook, f., Fl. Brit. Ind., i. p. 395; Oliver, Fl. Trop. Afr., i. p. 257; 

 Miq., Fl. Ind. Bat., i. 2, p. 197 (Triumfetta angulafa, Lam.) 



Timor Laut. — Common in Tropical Asia, and generally dispersed in Tropical Africa ; 

 also occurring in Tropical America. The seed-vessel of this species is covered with hooked 

 prickles. It is very variable in its foliage, the same variations being repeated in different 

 parts of its area. 



Triumfetta annua, Linn. 



Triumfetta annua, Linn. ; Hook, f., Fl. Brit. Ind., i. p. 396 ; Miq., Fl. Ind. Bat., i. 2, p. 196. 



Timor Laut. — Throughout Tropical Asia and Africa. This also has the seed-vessel 

 furnished with hooked prickles. A third, undetermined, species of this genus was collected 

 in Timor Laut. Triumfetta 2^rocumbens, Forst., is a seaside species common in Polynesia, 

 and in some islands of the Malayan Archipelago and Indian Ocean, also occurring on 

 maritime sands in North-eastern Australia. In the Kew Herbarium there are specimens 

 from Diego Garcia, Chagos Islands, Indian Ocean, and from several remote islands of 

 Polynesia, such as Fanning, Suwarrow, and Endcrbury.
