3. Onax*. Calyx liber v. toro incrassato necnon ovarii basi plus minusve 
 adhzerens, fructifer ampliatus drupam involvens. Petala nunc sex per 
paria connexa, nunc quinque quinto libero. Stamina cum petalis basi 
connata, fertilia 3 petalis alterna, sterilia tot quot petala et iis opposita, 
filiformia, integra v. bifida. 
4. Scua@priat. Calyx toro incrassato necnon ovarii basi adherens, margine 
libero brevissimo truncato, fructifer drupam includens et ei adnatus. Co- 
rolla gamopetala 4-, 5-, 6-fida. Stamina tot quot laciniz corolle et iis 
opposita, omnia fertilia, filamentis tubo corollæ alte adnatis. Bracteole 
sub calyce parvee in cupulam inzequaliter 3—4-fidam connate. 
* ] have examined the flowers of O. stricta, Br., O. nana, Wall., O. zeylanica, Linn., O. scandens, 
Roxb., O. imbricata, Roxb., O. Wightiana, Wall., O. acuminata, Wall., O. macrophylla, m., and O. pauci- 
flora, m., and fruits of O. 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. 
O. acuminata (Wall. I. 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. zey/anice, foliorum forma, floribus minoribus paucioribus 
diversa.—Sillet, Wallich. 
O. macrophylla, sp. n., glaberrima, foliis ovato-lanceolatis acuminatis inæquilateris, 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 vix semipolli- 
cares, floribus circa 10 albis.—In monte Padawan Guianz Anglicz 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 provincie Bahiensis, Brasiliz, 
Blanchet, n. 2795. An hnc Dulacia singularis Vell. Fl. Flum. 1. t. 78.? 
Among the species enumerated in Wallich's List, n. 6777. O. lucida appears to be O. Wightiana ; 
n. 6778. O. Bador is correctly referred by Wight and Arnott to O. scandens; n. 6780. O. Heyneana 
is Gomphandra polymorpha, Wight; and n. 6782. O. 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.
