NEW GENERA OF W. AUSTRALIAN PLANTS. 55 
apice truncata, angulis dorsalibus porrectis, lateribus compressis. 
Styli duo in unicum glabrum coaliti; stigma incrassatum, bilobum. 
Capsula dicocca, coccis cornutis, bivalvibus, endocarpio cartilagineo, 
elastice soluto, abortu monospermo.—Fruticulus abitu Phebaliis 
simillimus, pube squamosa vestitus; foliis ovatis basi im petiolo an- 
gustatis ; floribus albis terminalibus umbellatis, pedicellis filiformibus 
squaimosis. 
Urocarpus phebalioides, J. Drum. 
Haz. By the side of a watercourse, east side of Mount Lesueur, rare. 
— Very similar in general aspect to Phebalium grandiflorum, but smaller, 
and differing essentially from Phebalium in its ovary and fruit. 
PHYTOLACCES ? 
MacanTHURIA apetala, Harv.; ramis scirpoideis ramosissimis, foliis 
paucis sparsis angustissime linearibus mucronatis, cymis paucifloris, 
floribus apetalis octandris trigynis. 
Has. Northern districts. — I introduce this species for the pur- 
pose of calling attention to the natural position of the genus Macar- 
THURIA, Hug., which appears to be very ill placed in Biittneriacee, and 
perhaps may be better associated with Phytolaccee, with which Order 
it agrees in habit. The present species is much more slender than Jf. 
australis, I have examined many flowers of both, and never found 
more than eight stamens in any; as is also stated by Steetz in the - 
appendix to Pl. Preiss. 
CUNONIACEJE. 
9. PrATYPTELEA, J. Drum.—Calyz tubo turbinato, cum ovario connato, 
limbo semisupero quadripartito persistente fructifero aucto. Petala 
Stamina 8. Ovarium basi cum calycis tubo adnatum, apice _ 
liberum, conieunt, quadriloculare, Styli 4, discreti, filiformes; s/ig- —— 
mata simplicia. Capsula calycis tubo tetragono adnata, limbo aucto — 
stellatim patente coronata, abortu unilocularis, monosperma.—Suf- - 
frutices graciles, glabri; ramis volubilibus ; foliis oppositis linearibus 
integerrimis vel remote serrulatis; floribus oppositis pedunculatis, = 
peduneulo articulato (i. e. cyma uniflora). : 
Platyptelea clematidea, J. Drum. : 
Has. Crevices of limestone rocks in ihe Champion Bay district. 
—The specimens examined were in fruit. The stamens had fallen, -
