HITHERTO UNDESCRIBED PLANTS FROM ARNHEIm's LAND. 175 



CoRCHORUS CAPSULARIS. 



Linne, spec, plant. 529 (1753). 



Truly indigenous in the vicinity of Port Darwin, according to 



Mr. Holtze, who finds it there to attain a height of 6 feet. In 



:as much as also C. olitorius was found spontaneously growing on 



Van Diemen's Gulf ; furthermore as C. tridens, C. fascicularis, 



C. acutangulus were already seen by me far inland in Arnheim's 



Land, long before any settlements there were found, while C. 



trilocularis has been brought as wild under notice from several 



localities of eastern intra-tropical Australia, it seems safe, to admit 



.also C. capsularis now as an indigenous Australian species, 



.although it is one of the principal Asiatic Jute-plants. Seeds 



•occur sometimes also in the accessory cells of the fruit. 



Sterculia Holtzei. 



Tall ; branchlets thick, glabrous ; leaves chiefly terminal, on 

 slender petioles, simple, chartaceous, nearly ovate, occasionally 

 with a shallow basal sinus, of an almost equal light green and 

 nearly glabrous on both sides, entire ; racemes mostly crowded 

 towards the summit of the branchlets, partly compound ; flowers 

 small, their pedicels about half as long or shorter ; calyx ellipsoid- 

 urceolar, outside dull yellowish-green and except on the summit 

 glabrous, inside bearing extensively a thin but dense pale some- 

 what papillular indument, the lobes spreading, of about one-fourth 

 the length of the tube, semi-lanceolar, inside beset with short 

 spreading hairlets ; staminal column glabrous, shorter than the 

 globular-ovate mass of anthers or nearly as long ; stigmas re volute, 

 considerably shorter than the style ; ovularies grey from a close 

 starry vestiture ; ovules 3-4, rarely 2. 



Tree, 30 to 40 feet high. Bast pale, very tough. Leaves 

 probably annual, 3-4 inches long, 1^ to 2 inches broad, so far as 

 seen ; their secondary venules faint. Petioles about one inch 

 long. Stipules small, tomentellous, from semilanceolar to deltoid, 

 fugacious. Racemes measuring 2 to 3 inches in length, their 

 peduncles and pedicels glabrous. Calyx about J inch long. 

 Stamens at the base of the muturating pistils rather copious. 

 Ovularies very obliquely ovate. Fruit not yet obtained. 



This species is easily distinguished from S. Edelfelti in leaves 

 much broader towards the base and blunter at the apex, in less 

 turgid somewhat longer calyces with lobes less broad, also less 

 invested and not cohering during anthesis, while the fruits are 

 likely also different. 



Goodenia Pumilio.

Of this puny but remarkable plant Mr. Holtze has recently 

 sent well developed specimens, from which the characteristics
