the flower, the pollen being probably shaken by the fall of the 

 lid. 



(19.) Dipodium punctatum is a leafless plant with a raceme of 

 purple flowers. This is the only species known here, but Dr, 

 Mueller alludes to two other species, D. ensifolium and D. 

 venosum, of which latter, a straw-coloured variety occurs in New 

 England. 



(20.) The genus Cymbidium is now divided, so that one of our 

 species (0. reflexum) is referred to Sturmia. Of this, Dr. Mueller 

 remarks that it is known only to him from our Parramatta 

 specimens. It is abundant on our creeks to the north, and I 

 have also seen it in gullies in the county of Camden, but it does 

 not extend to Victoria. S. ccelogynoides grows at the Clarence, 

 and S. habenaria at Buckingham Bay. Oymbidium suave extends 

 from Illawarra to Moreton Bay, and C. caniculatum, although 

 occurring in the northern parts of this colony, is more widely 

 diffused through the arid regions of the tropics. The tender parts 

 of the stem, and the base of the leaves, afford a mucilaginous 

 food. 



(21.) Dendrolium is a genus generally epiphytal, and compre- 

 hends many species, some of which are as yet but imperfectly 

 known. D. speciosum (our Rock Lily), D. linguoeforme, and D. 

 cemulum are plentiful here, but D. pungioforme, D. teretifolium, 

 and D. Shepherdii are less frequent. To Brown's D. undulatum, 

 D. caniculatum, and D. rigidum, Dr. Mueller adds D. Milligani, 

 D. Mortii, D. Beckleri, D. monophyttum, D. tetragonum (Allan 

 Cunningham), D. elongatum (A. Cun.), D. Brisbanense, D. minu- 

 tissimum, D. exiguum, D, aurantiacum, and D. Kingianum. D. Cu- 

 cumerinum was found by the late Mr. W. 8. Macleay, near Brown- 

 low Hill, growing on the swamp oak, and the Australian D. bi- 

 gibbum has been cultivated in England. Nearly allied to this 

 genus are the species of Sarchochilus, viz. S. falcatus, S. Hillii, 

 S. Gunnii, and S. calcaratus, the first two of which occur at Tomah, 

 and were also found near Camden by Sir William Macarthur. 



The remaining Orchids mentioned by Dr. F. Mueller are the 

 following: Epiblema grandiflorum (Cape Le Grand, &c.), Oeodo- 

 TU pictum (Buckingham Bay, &c.), Phajus grandifolius (Queens- 

 land), Habenariaochroleuca(Rock'mgha,m Bay), Pholidota imbricata 

 (Kockingham Bay), Calanthe veratrifolia (Hastings River, &c.),
