coloured tips. The stamens have orange pollen. The nectary 

 scales are broadly obcuneate or wedge-shaped (see fig. 10 b) and 

 reddish; they secrete large drops of honey. The carpels are green, 

 oblique-ovate with a well developed style and a small stigma; 

 when ripe each contains several (about 6) brown, shortly oblong- 

 cylindrical seeds with a finely rugose testa. 



The Australian species comes near to the South-African C. 

 decumbens Thunb. (Bulliarda trichotoma Eckl. &Zeyh., see Schön- 

 land, 1. c, 53). 



Geogr. Area: Extra-tropical Australia and Tasmania.

In his Fragmenta XI, F. v. Müller men- 

 tions (118), under Tillæa macrantha, a new 

 form of which he gives the following descrip- 

 tion: Varietatem pedicellosam, pedicellis pie- 

 risque elongatis calyce pluries multotiesve lon- 

 gioribus detexi in pascuis fertilioribus collinis 

 ad basim montium Stirlingi; hæc varietas 

 quasdam Mitrasacmes species simulat præser-r 

 tim etiam ramificatione parciore v. parcissima 

 et inflorescentia passim quasi umbellata, nisi 

 hæc planta forsan speciem seorsam (pedicello- 

 sam) exibet. 



Shortly after (1882) he enumerates it as 

 a distinct species, but has, as far as I am 

 aware, not given any more elaborate descrip- 

 tion of it. As the description quoted is very 

 incomplete, and as I have no authentic speci- 

 mens of the species at my disposal, it is with 

 some doubt that I identify with it a small 

 Crassula found near Armadale; but neverthe- 

 less I think the identification a correct one, 

 and my plants agree with specimens kindly 

 sent me by Mr. J. M. Black from S. Australia 

 under the name of Tillæa macrantha var. pedicellosa. 



The plant in question is a small erect annual (1 — 5 cm high),
