called "Sturt's Desert Rose." Flowering, May, 1917. Agrees 

 exactly with specimens in the Tate Herbarium from the Vic- 

 toria Desert, September 15, 1891 (R. Helms). Style-branches 

 pubescent near the summit, spirally twisted and united up 

 to the 5 red, capitate stigmas, thus conforming with Gaudi-

 capitato") and with the accompanying plate. Ovary 

 glutinous, pubescent; calyx 25 mm. long; petals nearly 6 cm. 

 long, with a small tooth on one side. [Makes a shapely bush 

 up to 4 feet 6 inches tall, covered in beautiful bluish-purple 

 blossoms; sandhill country seems to be its habitat.] 



Sida intricata, F. v. M. Sixty miles along the East-West

Ooldea, flowering in January, 1917 (S. A. White). 

 Allied to II . fasciculata, R. Br.; II. elata, Maiden et Betche ; 

 and H . virgata, R. Br., but differs in the much longer leaves, 

 more numerous stamens and ovules, and in being a desert 

 plant. Moreover, there appears to be constantly only one 

 bract at the base of the flower, and this bract is placed 

 opposite to the uppermost leaf. [Often met with in the sand- 

 hills around Ooldea in full flower ; grows into a shapely bush 

 up to 2 feet 6 inches or 3 feet high.]
