 suppl. p. 342. Melaleuca aestuosa, Forst. prod. no. 215. Mel. 

 spectabilis, Gaertn. fr. 1. p. 172. t. 34. f. 9.? Leptospermum 

 collinum, Forst. gen. 36. no. 2. appears to differ from this, 

 according to the description, in the leaves being glabrous on 

 both surfaces, in the petioles being velvety, and in the calyx 

 being truncate from the limb being deciduous ; it is therefore 

 perhaps a different species.

 leaves scattered or nearly opposite, elliptic, obtuse, coriaceous,

 Holland, on the eastern coast.

 petals. From the stigma being 

 capitate (f. 1 SO. 4.) in this as well 

 as in 717. capilata and M. erici- 

 fblla, these plants will form a dis- 

 tinct genus, which might be called 

 Gynocephala.
