414 XXXVI. UHAMNEiE, 



5. ALPHITOlSriA, Eeissek. 



Calyx 5-lol)ed, spreading. Petals involute. Stamens 5, included in the 

 petals. Disk ttick, filling the calyx-tube. Ovary immersed in the disk, 

 2- or rarely 3-cclled, tapering into a shortly lobed style. Drupe glohular or 

 broadly ovoid, the epicarp of a dry, mealy or somewhat corky substance; en- 

 docarp of 2 or 3 hard coriaceous nnts or cocci, opening inwards by a longi- 

 tudinal slit. Seeds with a shining hard testa, completely enclosed in a 

 membranous brown shining arillus, open at the top, but with the edges 

 folded over ; albumen cartilaginous or horuy ; cotyledons flat. — Tree. Leaves 

 alternate, penuiucrved. Cymes dichotomous, many-flowered. Seeds often 

 persisting on the torus after the pericai"p has fallen ofl^. 



The genus is probably limited to a single species, ranging from Australia to the Pacitic 

 islands, 



1. A. excelsa, Rehseh, in EndL Gen. 1098. A tall hard-wooded 

 timber-tree, the young branches, petioles, and inflorescence hoary or rusty 

 with a close tomentum. Leaves petiolate, varying; from broadly ovate or 

 almost orbicular and verjfc obtuse, to ovate or lanceolate and acute or acumi- 

 nate, usually 3 to 6 in. long, entire, coriaceous, glabrous or slightly hoary 

 above, white, or rarely rust-coloiu*ed nnderneath with a close tomentum, the 

 parallel pinnate veins very prominent. Plowers 2 to 3 lines diameter, m 

 little nmbel-like cymes, arranged in dichotomous cymes in the upper axils or 

 in a terminal corymbose panicle. Calyx tomentose. Disk broad and nearly 

 flat. Emit 3 or 4 lines diameter, or sometimes rather larger. — CoUihnnd 

 excelsa^ Penzl, in Hueg.'Euum. 20. 



W. Australia. Islands of the Gulf of Carpentaria (Cape Van Diemeii), R. Brown; 

 Sweers Island, llenne ; Arnhem's Land, F, Mueller. 



Queensland. Curtis Island, Remie; Rockliampton, Thozet; Port Denison, Ftf^^tfan; 

 Brisbane river, Morcton Bay, A. Cunningham, Frnser, F. Mueller, and others. 



N, S- Wales. Hunter's, Paterson's, and Williams rivers, ^. Brown; Hastings and 

 Clarence rivers, Beckler and others ; Blue Mountains, Miss Atklmon ; Illavvarra, M' Arthur, 



The Carpentaria island specimens belong to a variety with remarkably large obtuse leaves, 

 the flowers rather larger than usual, and the tomentum somewhat rusty. To this belongs 

 Zizyphus pomaderroidesy Fenzl, in Ilueg. Eiium. 20, judging from R. Brown's specimens 

 corresponding to Bauer's. Alphiionia ziz^phoides, A. Gray, Bot. Amer. Expl. Exped. i. 37B, 

 t. 20 {Rhamnus ziz}jphoides, Soland.), which extends from Borneo and Nevt Caledonia to 

 the Pacific islands, does not appear to differ at all from some of the eastern Australian spe- 

 cimens ; whilst A.franguloides, A. Gray, 1. c. 280, is very like some of the more tomentose 

 N. Australian specimens. 



C. EMMENOSPERMUM, P. MiicU. 



Calyx 5-!obcd, the tube campaniilate. Petals hood-sliaped, inserteJ with 

 the stamens on the margin of the disk. Stamens 5, enclosed in the petals. 

 Disk thin, lining the calyx-tube. Ovary inserted on the disk in the bottom 

 of the calyx -tube, but not immersed, 2-cclled or rarely 3-celled, tapering into 

 a shortly-cleft style. Fruit almost capsular, with a very thin almost dry epi- 

 carp, the endocarp separating into 2 or rarely 3 cartilaginous almost crusta- 

 ceous cocci, opening along the inner face in two valves. Seeds inserted on 

 a turbinate or slightly cup-shaped funicle, without any arillus ; testa hard and 

 shining; albumen cartilaginous- cotyledons flat, — Trees, Leaves opposite
