R, T. 35. G. filamentom (R. Br.)— This beautiful dark- 

 crimson form is widely distributed throughout 

 the Island. I know only of one locality on the 

 mainland where it is to be found, viz., Monarto, 

 near Murray Bridge. It has struck me as an 

 interesting fact that "C. tentaculata," a closely- 

 allied light-coloured species, so common around 

 the northern and western sides of the Gulf, does 

 not occur on the Island. I have found both 

 forms at Monarto. Blooms September, October. 



R, T. 36. C. dilatata (R. Br.)— Dudley Peninsula, Kings- 

 cote, Ravine de Casoars. Blooms September, Oc- 

 tober. 



R, T. 37. C . Patersoni (R. Br.) — This species has so long 

 been considered a legitimate dumping-ground 

 for divergent forms that perhaps no apology is 

 required for placing still another under this 

 heading. The Kangaroo Island form may con- 

 veniently be placed here for the present, 

 although it seems to me a very distinct type. 

 So far I have been unable to discover the pre- 

 sence on the Island of the forms which are so 

 prevalent on the contiguous mainland, e-g., 

 Yorke Peninsula. As in the case of C. filamen- 

 tosa, the only place in the State in which I have 

 known the Kangaroo Island form of C . Patersoni 

 to occur is Monarto, where I have collected it 

 at about the same time of the year. It has a 

 narrow leaf, varying from linear-lanceolate to 

 oblong-lanceolate. The flower is usually soli- 

 tary, the general colouring being yellow with red 

 markings. The latter are shown by a red line 

 running down the middle of each perianth seg- 

 ment, by the strongly-marked red clavate points 

 of each sepal, and by the red tip of the labellum. 

 There are four rows of calli, and the margins 

 of the labellum are denticulated, though not 

 deeply so. The caudse are comparatively short 

 and not hairy, as in the typical forms of G . Pat- 

 ersoni. Next to G . filamentosa, this is the most 

 prevalent "spider" west of Kingscote. 



R, T. 38. G . latifolia (R. Br.) — Kingscote, Harvey's Return, 

 Ravine de Casoars Creek, and very common on 

 Dudley Peninsula. Blooms September. 



R, T. 39. G . carnea (R. Br.) — Not common, but widely dis- 

 tributed. I have found it on Dudley Peninsula,
