Hemigenia pungens (Hemiandra pungens, R. Br. Prodr. 502 ; . 
Benth. Flor. Austral. v. 109 eum saltem aliquot synonymis) 
naseitur ad Geograph-Bay, Preston- et Blackwood-River prater 
locos jam indieatos. Corolla in statu typico albida paulo ccrules- 
cens, pulehre punetata, ut jam R. Brown scripsit. Ad fluvios 
Irwin's, Arrowsmith's et Greenough's River plantam legi fortasse 
H. pungenti adseribendam, eujus autem labium calycis superum 
lacinias tres fere zquales latiuseulas gerit ; tali modo transitus 
indieatur ad Hemigeniam Bartlingii (Hemiandra ineana, Bartl. in 
Lehm. Pl. Preiss. i. 357), quz quoque ad Boxvale ab Julia Wells 
reperiebatur. Aliam formam, nempe pedicellosam, nisi speciem 
seorsam in vieinia sinus Shark-Bay observavi; hujus stirpis 
preter corollam glaberrimse pedicelli setacei calyce demum duplo 
longiores, bracteole perbreves, ealyeis tubus fere obconicus labiis 
brevissimis pluries longior, corolle purpureze lobi quinque fere 
zequilongi et omnes breviter et zequaliter bilobi, antherze staminum 
breviorum appendice cylindracea scilicet imberbi loculum zequante 
pene antherz s$taminum longiorum haud distinete appendicu- 
ate. 
Hemiandra leiantha (Hemigenia leiantha, Benth. Flor. Austral. 
v. 110) varietate foliis brevioribus et latioribus vieiniam sinus ' 
Shark-Bay attinet. Labium corolle inferum supero eminenter 
longius. Distinetio hujus stirpis ab H. pungente nondum prorsus 
perspieua. 
Variabilitas appendieis antherarum intra Prostanthere genus 
sequo jure junetionem generum Hemigeniw et Hemiandre jubet.
