* I have examined the flowers of 0. stricta, Br., O. nana. Wall., 0. zeylanica, Linn., O. scandens, 

 Roxb., 0. imhricata, Roxb., 0. Wightiana, Wall., O. acuminata. Wall., O. macrophylla, m., and O.pauci- 

 flora, m., and fruits of 0. nana, zeylanica and scandens. Among the above species the following are 

 as yet undescribed : — 

 O. nana (Wall. Cat. Herb. Ind. n. 6783.), sufFruticosa ? glabriuscula ramis erectis parce ramosis, foliis 



subsessilibus oblongis lanceolatisve obtusis vix mucronulatis, pedicellis axillaribus solitariis uni- 



floris, calyce libero, staminibus sterilibus bifidis. — Napalia } Wallich. 



0. acuminata (Wall. 1. c. n. 6781.), fruticosa scandens? glabra, ramis angulatis, foliis ovato-lanceo- 

 latis acuminatis, racemis brevibus distichis paucifloris, calyce toro incrassato basi breviter adnato, 

 staminibus sterilibus bifidis. — Affinis O. zeylanica, foliorum forma, floribus minoribus paucioribus 

 diversa. — Sillet, Wallich. 



O. macrophylla, sp. n., glaberrima, foliis ovato-lanceolatis acuminatis insequilateris, racemis axillaribus 

 brevibus distichis, calycibus glabris ovarii basi adnatis margine libero truncato, staminibus ste- 

 rilibus integris v. vix emarginatis, ovario glabro. — Folia 4-6-pollicaria. Racemi \ix semipoUi- 

 cares, floribus circa 10 albis. — In monte Padawan Guianae Anglicae leg. Schomburgk. 



O.pauciflora, sp. n., foliis ovatis junioribus ramulis pedicellisque puberulis, pedunculis axillaribus 1-3- 



floris, calycibus molliter pubescentibus ovarii basi adnatis margine libero brevissimo truncato, 



staminibus sterilibus longe bifidis, ovario villoso. — Serra Acurua provincise Bahiensis, Brasiliae, 



Blanchet, n. 2795. An hue Dulacia singularis Veil. Fl. Flum. 1. t. 78. ? 



Among the species enumerated in Wallich's List, n. 6777. 0. lucida appears to be 0. Wightiana -. 



n. 6778. 0. Bador is correctly referred by Wight and Arnott to 0. scandens; n. 6780. O. Heyneana 



is Gomphandra polymorpha, Wight; and n. 6782. 0. longifolia is Gomphandra axillaris, at least the 



letter A ; the letter B may perhaps be a different species of Gomphandra. 



t Of this genus I have examined S.fragrans, Wall., in flower and fruit, and a Brasilian species, in 



flower only, from Serra Jacobina (Blanchet, n. 2593), perhaps S. arborescens, but my materials do not 



at present admit of my determining the species with certainty.
