Capparis arborea Maiden Fl. Norf. Isl. 696 (1904), p. p. 
Foliis coriaceis anguste oblongo-elliptieis utrinque acutis circa 
1—10 em longis et 3—3!/, cm latis (3:1), drupis laevibus mammoso- 
acuminatis. 
Southern Queensland: Brisbane River, F. v. Mueller, Aug. 1855; 
Fraser 1829 with broader leaves (10 cm X 4!/, cm). 
32. Capparis nobilis (Endl.), F. v. Muell. var. laurina Domin, nov. var. 
Foliis majoribus late ellipticis brevius petiolatis basi saepe rotundatis 
81/4—10 em longis et circa 5 cm latis, drupis laevibus umbone minimo 
instructis. | 
Southern-Queensland: Moreton Bay, A. Cunningham, 
Occurrit forma glabrifolia et foliis subtus hispidulo-subpubescentibus 
„var. pubescens Benth.). 
33. Pittosporum queenslandicum Domin, nov. spec. 
Arbor glabra. Folia in ramis sat distantia (nec verticillato-con- 
feria) magna late ovata acutiuscula vel subobtusa basi in petiolum con- 
Spicuum sed brevem usque plus 1 em longum cuneato-angustata utrinque 
glabra vel supra papillis minutissimis dispersis sub lente tantum con- 
spicuis instructa, integerrima sed margine crassiusculo minute fevoluta, 
crebre reticulato-venosa parum coriacea fere herbacea subtus sordide 
viridia nec glauca supra saturatius viridia circa 8—11 cm longa et 
37—54 mm lata, venis reticulatis subtus coloratis saturate violaceo-brunneis. 
Panicula terminalis pauciflora subsessilis foliis brevior solitaria. Cap- 
sulae subglobosae leviter compressae minores bivalvatae paucispermae. 
Valvae rugulosae ligneo-coriaceae intus luteae 7—9 mm longae et to- 
tidem latae vel saepius longitudine latiores. 
Queensland: Keppel Bay, Rob. Brown (Iter Australiense 1802—1805, 
no, 5449). 
Species P. venuloso F. v. Muell. Fragment VI, 186 (1868), cujus speci- 
mina originalia a cl. Dallachy in sinu Rockhingham Bay collecta com- 
paravi, proxima, sed haec foliis minoribus angustioribusque valde coriaceis 
lanceolatis vel ovato-lanceolatis (ex descriptione verticillato-confertis), 
capsulis duplo majoribus plus lignosis facillime dignoscitur. 
P. melanosporum, cum quo cl. Bentham speciem nostram conjunxit, 
primu aspectu foliis valde coriaceis minoribus, nervis pallidis (nec vio- 
laceo-fuscis) diserepat.
