close approach is offered by this plant also to Cryptogramme with 

 which genus Prantl (in Engl er 's Botanische Jahrbücher, III, 413), 

 unites Onychium and Llavea. Whether our new fern, which is pre- 

 ferentially placed under Cheilanthes but just as well referable to 

 Cryptogramme, has the generally dimorphous fronds of the last men- 

 tioned genus, remains to be ascertained. 



In habit this fern closely resembles Pellaea pilosa, P. Bojeri, P. 

 densa, and Cheilanthes pulchella. The generic position, assigned to it, 

 is rendered all the raore justified, as Cheilanthes subvillosa has also a 

 continuous equally wide and rather ample indusium. Moreover the 

 general similarity of 0. Clelandi to C. Prenticei is very remarkable, 

 though the latter, which as yet is only known from Thursday Island 

 in Torres Straits , conforms with the ordinary type in the genus as 

 regards narrow irregulär and somewhat crenulate reflection of the 

 frond-margin for forming indusia over crowded sporangia, while the 

 underside of the fronds is clothed with short hairs and the veins are 

 much less prominent. Finally it may be added that C. Prenticei is 

 closely allied to C. fragillima. 



Newcastlia Dixoni. 



An erect undershrub, moderately branched, attaining to two feet, 

 densely tomentose; leaves from rhomboid to cordate - ovate , sessile 

 rather short, flat, thinly tomentose on both sides with whitish branched 

 hairs ; lobes of the calyx narrow semilanceolar, considerably longer 

 than the tube ; coroUa about thrice as long as the calyx , slightly 

 bearded inside near the base, otherwise almost glabrous; coroUa-lobes 

 narrow semilanceolar, nearly as long as the tube ; stamens hardly half 

 as long as the corolla-tube, inserted near the base ; anthers cordate- 

 orbicular ; style short, as well as the ovary glabrous. 



On sand-ridges at Ral-ral on the River Murray, 30 miles from the 

 Victorian border ; also at Crystal Brook ; Mr. Samuel Dixon. 



Leaves from one-third to two-thirds of an inch long and nearly as 

 broad. Calyces thinly tomentose outside. CoroUa almost half an inch 

 long. Ovary longer than broad, attenuated into the style. 



Nearest to N. spodiotricha as regards form of corolla and anthers, 

 but in other respects very different. 



The two foUowing species are also additional to the flora of extra- 

 tropical South Australia: — 



Stenopetalum croceum Bunge (emended by F. v. M. in Frag. Phyt. 

 XI. 6), at lunaminka on Cooper Creek (Mr. James McLeod!), the 

 trisect petals are yellow. This plant has hitherto been known only 

 from the western districts of West Australia. 



Geijera salicifolia. — This graceful tree has now been traced by Mr. 

 Samuel Dixon from the River Darling district into South Australian 

 territory to Ral-ral on the River Murray.
