The genus Callitriche, which Bentham includes in this Order, 

 is omitted by Prof. Schindler; in the system used in Engler's 

 ! Pflanzenreich ' it is placed in a separate Order, Callitrichacese. 



After revising the material in the National Herbarium from 

 Prof. Schindler's Monograph, we requested Mr. R. T. Baker to 

 send us all his Halorrhagacese for revision, to which he kindly 

 x'esponded, and we have to thank him for his permission to 

 describe the following new species we found amongst his material. 



Halorrhagis verrucosa, n sp. 



Woodburn, Richmond River; W. Bauerlen; December, 1894. 



A perfectly glabrous annual about 1 to 1 \ feet high, branched 

 from the base, with slender 4-angled and slightly winged stems 

 and branches. Stem-leaves opposite, very shortly petiolate or 

 almost sessile, distant, in all specimens seen from \\ to above 3 

 inches apart, lanceolate, |- to y 9 ^ of an inch long, and at the most \ 

 of an inch broad, acute, remotely serrate, with the whitish recurved 

 margins so frequent in the genus; floral-leaves reduced to very 

 small alternate bracts, quite minute under the uppermost flowers. 

 Racemes filiform in a terminal panicle, the flowers solitary and 

 very shortly pedicellate within the bracts. Bracteoles very 

 minute or absent. Calyx-tube ovate, submembranous, glabrous, 

 faintly 8-ribbed and densely covered with whitish callosities, 

 about 10 between the ribs; the lobes triangular, shorter than the 

 tube, without any distinct basal callosities, and not cordate. 

 Stamens 8. Fruits mostly 1-celled.
