THE VICTORIAN' NATURALIST. 57 



In a gaily ueai- Berwick, .ami owaeJ by Mr. R. Bain, this plant 

 may be found growing in perpetual moisture, when the whole plant 

 becomes so brittle, that it falls to pieces when exposed to light and 

 air. It may be recognise I chiefly by its color, also by its slender 

 appearance and semi-glabrous leaves. To grow it well, use leaf 

 mould, with plenty of shade, and water, and if possible, try to 

 obtain the specimens from the driest parts of the places where it 

 grows. In a place called the Pound Bend, near Warrandyte, this 

 plant used to be growing by the hundreds, even although the 

 ground near the river was covered with silt to a depth of 4 inches. 

 Flowers about December, and grows to a lieight of from 4 to 12 

 inches, the latter, only when "drawn" up by undergrowth Found 

 also in South Australin, New South Wales, and Tasmania. 



P. NANA, (R. Brown.) 



This pretty little orchid, filthough well marked, seems to have 

 caused some confusion as to which really is nana, which sp. sometimes 

 approaches very near to pale and small flowered forms of P. concinna^ 

 more especially as they are often found in company. Mr. Benthani 

 places this .'^7). near pedunculata, and, although I liave here adopted 

 his method of sequence in sp., I cannot find out in what respect 

 they are allied, because the general appearance, habit, color, &c., 

 are totally different, and the true nana seems to be much nearer fca 

 P. pyramichdis than to pedunculata, but this must be left to 

 specialists to work out, as any reduction of sj)., if made on scientific 

 grounds, will, I am sure, be always acceptable to those interested. 

 To return to P. nana, I may say that it is I0 be found near the 

 coast, often in the Ti-tree, and sometimes inland, when the forms 

 seem by exposure to become more robust. The color of flower is 

 a pale green, the leaves small, and in a radical rosette. The hood,, 

 (or galea) is narrower than thai of P. concinna, and I liave not 

 noticed the peculiar reddish tint, which in the former sp. is so 

 marked. This little plant is barely worthy of cultivation excepting 

 as an addition to a collection of native orchids, as it does not 

 remain long in flower, and is not neaily so hardy as its frequent 

 companion, P. concinna. Height from 3 to 6 inches. Found also 

 in New South Wales, Tasmania, and South Australia. 



P. I'KAKcox, (Lindley.) 



A very beautiful orchid, rather more common than tlie former 

 species, the habit and appearance leing somewhat similar, the 

 principal point of difference being according to Benthani, the narrower 

 leaves, smaller flowers, and on internal examination, broader sinus 

 between the lobes of the lower lip of tlie perianth. This sp. is to be 

 found generally on grassland, although I have collected specimens
