PAKRAMATTA DISTRICT. 15 



both as regards its size and the number of flowers on the same 

 stem. According to the doctor, it has a wide range in these 

 colonies, and extends to Tasmania. 



(8.) Microtis has J parviflora and M. rara in this district ; 

 but Dr. Mueller combines these and several others under M. 

 viridis. In addition to M. alba and M. pulchella, he mentions M. 

 atrata, from "Western Australia and Victoria. This genus ap- 

 proaches very near Spiranthes ; but the greenish spike of flowers is 

 not twisted. 



(9.) Acianthusfornicatus, with which A. exsertus is now joined, 

 is plentiful in many parts of the colony, and extends to Victoria ; 

 but A. caudatus, which in this district is a very rare species, is 

 found here and there from the Blue Mountains to Victoria, and 

 also in Flinders' Island and Tasmania. 



(10.) Cyrtosfylis reniformis is a minute orchid with a kidney- 

 shaped leaf. It is plentiful on shady creeks, generally growing 

 on moist banks, or under the shade of rocks. It extends to 

 Victoria. 



(11.) Chiloglottis dipliylla occurs in this district, and also in the 

 adjacent colonies, but here it may be regarded as rare. This and 

 the preceding species generally flower in autumn. 0. Gunnii as 

 well as G. diphylla occurs in Victoria. 



(12.) Eriochilus autumnalis is another minute orchid, and, as 

 the specific name implies, appears in the autumn. It has a wide 

 range, between St. Vincent's Grulf and Moretoii Bay. E. sealer 

 occurs at the Eiver Murchison, and JE. multiflorus at Kalga, &c. 



(13.) Galadenia is a very pretty genus, and some of the species, 

 especially C. ccerulea, C. alba, C. carnea, and G. testacea, are 

 abundant in the spring. C. Patersoni, I have found near the coast, 

 but it occurs more frequently in the interior, as I have received 

 specimens from the neighbourhood of Mudgee and also from the 

 Murrumbidgee. Dr. Mueller proposes to unite this interesting 

 species with (7. dilatata and some others under C. pulcherrlma. 

 The other species described by Brown are C. deformis, C. alata, 

 C. flava, C. latifolia, C. gracilis, 0, congesta, C. Jilamentosa, C. 

 Mienziesiij and C. macrophylla. To these, the Doctor adds C. 

 gemmata, C. unguiculata, C. ochreata, and C. barbata, combining 

 G. alata and G. angustata with C. carnea, and (7. mollis with G. 

 latifolia. During the last spring I paid particular atttention to G.
