78 ADDITIONS TO Ol'R FLOWKRIN(; IM.ANTS. 



ture of the Section Eucaladenia except in the peculiar 

 labellum. Stem, leaf, and outer surfaces of perianth lobes 

 delicately hirsute. Flowers usually one or two, externally 

 very pale green, each lobe marked in the centre by a narrow 

 red-brown line. Dorsal sepal erect with a recurved acute 

 apex, linear 1cm. Ventral sepals similar; lateral petals 

 rather broader. Labellum irregularly rhomboid to oblong- 

 acuminate flat, white, nearly as long as the lobes, apex acute 

 not at all recurved, lateral lobes obtuse forming simple ex- 

 pansions, bearing neither calli nor fimbriations. 



Gathered by Rev. H. B. Atkinson, M.A., on Natone Hill, 

 Lindisfarne, October, 1922. It has the erect dorsal sepal of 

 C. carnea and some of the purple colour of C. testacca, but 

 differs from both in the peculiar labellum. The only other 

 member of the genus with the absence of calli on the label- 

 lum is C. fimbriata of West Australia and that belongs to the 

 section Leptoccras. 



In the same locality Mr. Atkinson met with Ptcrostylis 

 carta, a plant not usually met with in Southern Tasmania. 

 It may be recognised from P. nutans by its erect flower and 

 blunter, shorter perianth lobes. 



Microtis atrata, Lindl. Usually about 3 inches high. 

 Green when fresh, darker when dry. The flowers are very 

 small crowded in a short spike. Flowers about one milli- 

 metre long, labellum entire broad, almost quadrate, not 

 callous. 



Near George Town. 



Pterostylis toveana, A. J. Eivart. This is an intermed- 

 iate form between /*. pracox and P. concinna. In Tasmania 

 we generally find it where these two are associated and con- 

 sequently suspect hybridisation. 



Pterostylis pcdoglossa, Fitz. With much the appearance 

 and tapering lobes of P. obtiisa it has a shorter, obtuse label- 

 lum and a rosette of leaves at the base of the stem. 

 It occurs at Eaglehawk Neck. 



Thelymitra luteocilium, Fitz. A robust plant with many 

 pink flowers and copious ciliate development of the column 

 lateral lobes. In the Flora I have treated it as a possible 

 hybrid between T. carnea and T. ixioidcs. 



For the last two determinations I am indebted to Dr. 

 Rogers and Mr. Pescott. 



The .sedge referred to in the P^lora as Carex barbata, 

 Boott, has since been described as a new species under name 

 Carex tasmanica.
