NOTES ON WEST AUSTRALIAN PLANTS. 
By O. H. Sargent.* 
Actinotus superbus, sp. nov. Herba annua; caule erecto tereti 
pinguiuseulo subdense piloso interdum parce ramoso foliis radi- 
calibus longe petiolatis petiolis linearibus lamina bis tripartita seg¬ 
ments ultimis brevibus elliptico-oblongis subacutis ; foliis caulinis 
subsessilibus in segmenta lanceo-linearia 2 vel 3 divisis; umbellis 
longe pedunculatis in paniculam dispositis ; bracteis involucralibus 
linearibus praesertim in marginibus paginaque sup. densissime albo- 
sericeis ; floribus pentameris hermaphroditis maribusque commixtis ; 
pedicellis uti ovaria calycesque dense pilosis; calycibus hyalinis 
campanulatis lobis breviter triangularibus in comis occultis ; petalis 
flavidis anguste lanceolatis ; antheris tlavis elliptico-oblongis. 
Herba ad 18 cm. alta; petioli 15-20 mm. long. ; laminae 18— 
25 mm., pedunculi 2-0 cm. (plerumque 4 cm.), bracteae 17-24 mm., 
quam tlores circa triplo longiores. Herb. Sargent. 1398. 
The affinity of the new species is undoubtedly with A. leuco- 
cephalus Benth., from which it differs conspicuously in its stouter 
sturdier stems, far more hairy bracts and flowers, in the shape of the 
calyx lobes and colour of the anthers. I have received it from 
Bulkuling and Doodenanning (20 miles E. of York), Quairading (still 
further east), and from Datatine (roughly 140 miles south of the 
other stations). This very beautiful plant is only found after a tire 
has swept its habitat. 
Actinotus leucocepiialus Benth. var. (?) nanella, var. nov. (?). 
Ilerba annua, parva (circ. 9-13 cm. alta), eompacta, basi ramosa ; 
bracteis involucralibus extends manifeste herbaceis, intends subdense 
pilosis ; umbellis maribus—hermaphroditis vel femineis in plantis 
disjunctis ; floribus iis A, leucocephali similibus, antheris atro-pur- 
pureis. Herb. Sargent. 1399. 
This remarkable gyno-polygamous plant is perhaps entitled to 
specific rank; but it is certainly close to A. leucocepiialus Benth., 
and it seems best for the present to regard it as a variety of that 
species. 1 have received it only from Datatine, where pistillate plants 
seem to be in a majority, from Miss Doutcli and Miss Good. 
Helipterum cryptanthum, sp. nov. Ilerba annua circa 10-30 cm. 
alta ; caule erecto simplici vel pauciramoso ; foliis late ovatis integris 
acutis subdecurrentibus; capitulis solitariis vel in paniculam dis¬ 
positis cylindrico-ovoideis paucifloris; bracteis scariosis interioribus 
petaloideis unguibus oblongo-cuneatis quam lamellm paullo longiori- 
bus lamellis erectis anguste-ovatis acutis integris vel dentibus api- 
calibus paucis parvis ; pap pi setis plumosis ; corollis infundibuli- 
formibus lobis suberectis. 
Bracteae petaloideae, roseae, unguis 6-7 mm., lamella 5-6 mm. 
longa, ambo ca. 2 mm. latae. Herb. Sargent. 1404. 
This species is homoplastic with 11. Manglesii F. Muell. (with
