290 Eivart, White and Wood : 



BoKONiA DENTICULATA, Sm. (Rutaceae). 



Donnybrook, West Australia, Max Koch, Oct., 1909. No. 

 1934. 



The specimen has the hirger sepals and more umbellate in- 

 florescence of ]i. fast If/ lata, Bartl., but has the longer pedicels 

 of B. denticulata. Other specimens join these two species, and 

 justify Mueller's inclusion of B. fastigiata as a variety of B. 

 denticulata. The distinctive features are the inflorescence, 

 leaves and sepals, all of which are variable and occur in various 

 combinations. 



Caladenia latifolia, R.Br., var. glandula, Ewart and Wood, 

 new var. (Orchidaceae). 



Lowden, Preston River, West Australia, Max Koch, Nov. and 

 Dec, 1909. No. 1944. 



The plant is somewhat more hairy and the leaves are shorter 

 and narrower. The chief differences, however, are in the flowers. 

 The perianth segments are dotted closely on the outer surface 

 with brown glandular hairs, especially towards the ends, and 

 they are more blunt than in the type Caladenia latifolia. 

 Owing to the lesser number of hairs, the veins show up 

 more clearly on the perianth of Caladenia latifolia. The 

 labellum in each is three-lobed, but in the variety, the middle 

 lobe is shorter than that of the type, and its margin is dis- 

 tinctly crenate. The flowers are pale yellow instead of pink or 

 white, as in the type. 



Caladenia Patersom, R. Br., var. dilatata. (Orcliidaceae). 



Lowden, Preston River, West Australia, Max Koch, Oct. 1909. 

 No. 1930. 



Calocepiialus Skeatsiana, Ewart and White. (Compo.sitae). 



Mr. Max Koch writes that the habit of this plant is quite 

 prostrate, the numerous branches are flat on the ground.
