A NEW GENUS OF DIOSME.E. 209 



immersis inconspicuis. Cymts terminates, trichotomae, multiflorae, pedunculo communi teretiusculo 

 vel compresso subpollicari, ramisque oppositis teretiusculis, pilis brevibus patulis velutinis nigres- 

 centes. Bractece subulatae, pilis longioribus lutescentibus appressis dense tectae. Pedicelli divaricati 

 ebracteolati (5-6 lin. longi). Calyx profunde 5-partitus, sepalis ovatis, carnosulis, extus margineque 

 hirsutis, intus glabris. Petala 5 (vel quandoque 4), calyce 5-plo longiora, aestivatione imbricata, sub 

 anthesi patentia, ovato-elliptica, brevissime unguiculata, basi sub 5-nervia, alba, undique pilis simpli- 

 cibus crispatis velutina. Stamina 8-10, hypogyna (persistentia?), petala subsuperantia, alterna iisdem 

 opposita paulo breviora ; filamenta omninb libera, lineari-subulata, laevia (sub anthera haud dilatata), 

 glaberrima: anthera introrsae, ovato-cordatas, glabrae, biloculares, rima longitudinali dehiscentes, 

 apice inappendiculatae. Ovaria 5, in germen pentagonum cohaerentia, gynophoro disciformi glabro 

 margine sinuato insidentia, unilocularia, villosissima, singula apice ad angulum externum glandula 

 tuberculove majuscule- sessili instructa. Ovula in quoque loculo gemina, sutiiras ventrali collateraliter 

 inserta, pendula. Styli ex ovariorum apice in unicum, glabrum, angulatum, subulato-linearem, sta- 

 mina subaequantem, germine subduplo longiorem, coaliti. Stigma subcapitellatum, vix lobatum. 

 Capsula sub-pentacocca ; cocci (quorum 1-3 saepe abortivi) basi subcohaerentes, sepalis persistentibus 

 pluries longiores, subquadrati v. rhomboidei, paulo compressi, basi rotundati, apice abrupte truncati 

 et angulo externo breve cornuti, coriacei vel sublignosi, dorso carinati, transversim rugosi, extus 



glabriusculi, intus sulcati glabri ; endocarpio haud secedente. Semina ? 



Hab. ad margines sylvae densae prope Portum Macquarie dictum, Insulae Van Diemen; ubi floribus 

 expansis legit Dom. Jos. Milligan mense Decembris 1846, et iterum Martii 1847. 



I take this opportunity of expressing my obligations to Sir William Hooker for having 

 kindly afforded me the opportunity of examining the flowers in a living state; thus 

 enabling me to supply some particulars with regard to colour, &c., on which little or no 

 satisfactory information could be obtained from the dried specimens. I regret to find, 

 however, that the plant is not likely at present to ripen its fruit at Kew. Mr. Smith 

 informs me it was first introduced to the Botanic Garden in 1845, in a case sent by 

 Dr. M'William from Norfolk Island, where, however, it is scarcely possible that it 

 should be indigenous.
