 (Extra print froui the Victorian Naturalist. 1888. August.) 



Two years ago the Rev. W. F. Schwarz of the Mission-Station on 

 the Finke-River ascended Mount Sonder in the Macdonnell-Ranges for 

 the purpose of gathering plants , particularly at its lofty and rocky 

 sunimit. Thus the leaves and peduncles of a plant were obtained, 

 which — though devoid of flowers and fruits — was referred to the genus 

 Actinotus, aud recorded preliminarily in the transactions of the Royal 

 Society of South Australia 1886 as A. Schwarzii. Recently the rev. 

 gentlenian reiterated this toilsome and rather perilous tour, and 

 succeeded in carryiug away from ahnost inaccessible declivities further 

 material for the elucidation of this and some other peculiar plants; 

 thus it is now possible to confirm the temporary position of this 

 Actinotus, aud to contrast it with allied species. It has the habit 

 of A. Heliauthi ; the tufts attaining a height and expansion of about 

 2 feet. Foliage and vestiture are also like those of A. Helianthi; the 

 peduncles are solitary, from few to several inches long; the umbels 

 resemble in size and indument those of A. leucocephalus , but the 

 involucral bracts are worn away already on the few specimens obtained, 

 must therefore be compared on some future occasion ; the numerous 

 pedicels are V4 iiich or less long; the flowers, still remaining unshed in 

 the aged umbels before me , are all staminate only , the filaments 

 hardly reaching beyond the calyx; the latter is densely beset with 

 soft whitish almost appressed hairlets; the anthers are also similar 

 to those of A. leucocephalus; the fruit remains unknown. Phyto- 

 geographically also the plant is quite noteworthy ; it is the only one 

 of this — to US endemic— genus , which reaches the tropic of capricorn, 

 and is also the only one which extends to Central Australia.
