which resembles V. lyrata that occurs frequently near Randwick ; 

 but it seems to be more closely allied to V. perfoliata, a species 

 somewhat rare, which Miss Atkinson found near the Valley of 

 the Grose. It is described in Brown's Prodromus as a species 

 belonging to Port Jackson and the Hunter, on the authority of 

 Alexander Gordon. The plant figured by Dr. P. Mueller has 

 not been found in this neighbourhood, and it seems to belong 

 almost exclusively to Victoria, as it was collected at the boundary 

 between the two colonies. Logania nuda is an almost leafless 

 shrub with small flowers, found principally on the banks of the 

 Murray. L. Jloribunda, which is common with us, differs very 

 much from this species in appearance* and character, and is one 

 of the few Australian flowers that is remarkable for its scent. 

 Our little L. pusilla is a very diminutive plant, with white flowers 

 and triangular interpetiolary stipules. L. nuda is elaborately de- 

 scribed by Dr. P. Mueller in the Pragmenta (vol. 1, p. 129). 

 Zehneria micrantJia, or Cucumis Muelleri, is an interesting plant of 

 the Cucurbitaceas or cucumber family, and in the Pragmenta it 

 is said to be indigenous on the Murray and the Darling. Some 

 little time since I received a specimen from Duck Creek, and I 

 felt pleased with it, as being one of a very small family in this 

 colony, for with the exception of our native gourd (Sicyos Aus- 

 tralis, or $. angulata), I am not aware that any other species of 

 the order exists near us. The figure of Loranthus eucalyptioides 

 of the mistletoe family is so much like the ordinary forms of 

 Loranthus prevailing in this colony, that I feel little hesitation in 

 claiming it as one of our native mistletoes. At present, there is 

 some difficulty in defining the species, as it seems that several 

 forms have flowers almost identical, whilst the leaves vary ac- 

 cording to the nature of the tree on which they are parasitical. 

 This circumstance has not escaped the notice of Dr. P. Mueller, 

 who remarks : " All the described species require a careful new 

 disquisition, as they are not only parasites of various plants similar 

 to each other, but also of genera of very different natural orders." 

 Thus, L. eucalyptioides produces, as long as it adheres to Eucalypti 

 or Casuarince, or now also to Virgilia capensis, long falcate leaves, 

 which, when the plant receives its nourishment from Banksia in- 

 tegrifolia assume an ovate orbicular shape, and a very fleshy con- 

 sistence, whilst the flowers become sessile. (Definitions &c., by
