This species has hitherto been regarded as a form of 

 K. ciliata, F. v. M., but the differences in the perianth, from 

 the bud onwards, seem to me sufficiently marked to justify 

 the creation of a new species. In K. ciliata the perianth has 

 conspicuous deltoid lobes, which close over the fruit, and no 

 appendage except the narrow annular wing; in K. coronata 

 the lobes are minute, irregular, inconspicuous, and recurved, 

 while from the summit of the perianth rises a crown-shaped, 

 truncate appendage, which helps to protect the fruit, especi- 

 ally as the long hairs which spring from the sides of the crown 

 are curved over it and guard the opening at the top. The 

 narrow wing which encircles the base of the perianth may 

 be likened to a brim, so that, with this crown and brim, the 

 fruiting perianth of K. coronata resembles a diminutive hat. 

 An inspection of the figures on plate ix. will help to make 

 the difference between the two species clear. That K . ciliata, 

 as here delimited, is the species represented by the type there 

 is no doubt, as Professor Ewart was kind enough to lend me 

 some of the original specimens gathered by D. Hergolt, col- 

 lector of Babbage's Expedition, in 1858, at Emu Springs and 

 Wonnomulla Water Hole, in the dry country lying to the 

 westward of the northern part of Lake Torrens. It was also 

 found by R. Helms (1891) at Cootanoorinna Creek, near the 

 Alberga River, together with K . coronata. Mueller's original 

 description of K. ciliata (Rep. Babb. Exped., 20) says: — 

 "Calyx wingless, fringed with woolly-villose hair, its teeth 

 deltoid ; fruit-bearing calyx flat-depressed, orbicular, without 

 ribs." Bentham, in the "Flora Australiensis," v., 188 (1870),
