PAEEAMATTA DISTEICT. 13 



with, the views of my eminent friend Dr. F. Mueller, as set forth 

 in the 35th number, vol. 5, of his Fragmenta PhyiograpJim 

 Australia, I am happy to find that the Parramatta district is not 

 only rich in orchids, but that the doctor has made especial 

 reference to several species found here. In a few instances Dr. 

 F. Mueller proposes to unite some of the generally received species 

 (such for example as Tlielymitra nuda and T. pauciflora, Acianihus 

 exsertus and A. fornicatus, Calocliilus campestris and C. paludosus, 

 and Microtis rara and M. parviflora), but after making allowance 

 for these alterations, it seems that we have upwards of forty 

 species in this district, some of which are regarded as rare and 

 interesting plants. The list, as amended, will now comprise the 

 following species : 

 Thelymitra ... 3 Acianthus ... 2 CorysantTies ... 1 



Diuris 3 Cyrtostylis ... 1 Caleana 2 



Ortlioceras ... 1 CMloglottis ... 1 Dipodiwm ... 1 

 Cryptostylis ... 1 Eriochilus ... 1 Cymbidium ... 2 

 Prasophyllum 4 Caladenia ... 4 Dendrdbium ... 5 

 Spiranthes ... 1 lyperanthus ... 2 



Calocliilus ... 1 Glossodia ... 2 45 



Microtis 1 Pterostylis ... 6 



(1 ) Ihelymitraixioides is one of our most admired orchids, and 

 has a very wide range, being found in many places between Port 

 Jackson and Port Phillip. It is abundant in the spring, and, with 

 its showy spike of bluish flowers, has the appearance of a cultivated 

 plant. T. nuda is a smaller flower, and generally the spike of the 

 flowers is very diminutive when compared with the preceding species. 

 T. carnea is of a dark pink colour, and on examination it will be 

 found that the structure of the flower differs from the other species 

 of this district in not having any of the segments terminated with 

 a little tuft of hairs. Dr. P. Mueller has described some new 

 species {T. Macmillani, T. pardalina, and T. porphyrosticta) , and 

 he also mentions (in addition to Brown's T. media, T. canicidata, 

 T. angustifolia, T. venosa, T. tigrina, and T. fusco-lcetd) , the species 

 T. antennifera, T.flexuosa, T. aristata, T. spiralis, T. variegata; but 

 it seems highly probable that the number is somewhat over-rated, 

 and that hereafter some of the so-called species will be united. 



(2.) The genus Diuris has three species in this neighbourhood, 

 D. maculata, or the spotted one, D, aurea which is generally larger
