338 NOTES AND EXHIBITS. 



referred to the African J . diffusa, or the Indian plant. It is 

 just possible that, as our plant extends from the north-eastern 

 coast to Victoria and South Australia, it may vary in the colour 

 of the petals and the development of the natatory organs, so that 

 whilst the northern specimens resemble those of India, the southern 

 ones may approach nearer the African form. Members of the 

 Linnean Society i-esiding in difterent parts of Australia, would do 

 service by collecting specimens of this Jussicea, and forwarding 

 them to the Council of the Linnean Society for comparison. 



II. On some Plants from the Lachlan. 



(1) Hibiscus Sturtii (Hook.). This plant which was first 

 noticed by the late Sir Thomas Mitchell (see Trop. Aust. p. 363), 

 is remarkable for its monophyllous involucre, almost wholly con- 

 cealing the calyx. The flowers are described as pui'ple, but they 

 are probably pink when fresh. Mr. Bentham, who had before 

 him specimens from different parts of Australia, says the species 

 is very varialjle, but that it may always be known by its cup- 

 shaped involucre. 



(2) Glycyrrhiza psoraleoides (Benth.) was collected by Mitchell 

 and Sturt, and Baron Mueller has figured it in his " Litho- 

 grams of Victorian Plants." The genus was named originally 

 from the sweetness of its roots, but the Liquorice of commerce is 

 now known as Liquoritia officinalis. 



(3) Helichrysum, semipapiyosum (DC). There are many varieties 

 of this plant in the Australian colonies, and Mr. Bentham was 

 inclined to include them all under H. ainculatum. The specimen 

 from the Lachlan seems to be distinct, and differs very much in 

 habit from any varieties near Sydney, though agreeing in pappus. 



(4) Isoetopsis graniinifolia (Turcz.) is a very carious little 

 composite. It is the solitary species of a genus endemic in Aus- 

 tralia, and common to four of the colonies. 



(5) Justicia procumbens (Linn.) in its small and erect variety 

 is common to Asia and Africa, as well as Australia.
