2. B. occidentalis. — Since the preceding sheets were printed, we have seen 

 a fragment of Mr. Nuttall's Saxlfraga data, which proves to be a true Boyki- 

 nia, only differing from B. occidentalis (as far as the imperfect specimen af- 

 fords the means of comparison) in the brownish chaffy hairs which clothe the 

 petioles and base of the stem, but which are, we suspect, deciduous. The 

 flowers are in better state than those of our B. occidentalis. The turbinate- 

 campanulate calyx is coherent with the ovary nearly to the base of the styles, 

 which are not longer than the free portion of the tube ; the teeth about one- 

 third the length of the oblong-spatulate petals; the calyx in fruit urceolate. 

 The stamens do not exceed the short calyx-teeth in length. 



Note. — The name of Mr. Nuttall's genus Cristatclla is changed by Endlicher 

 {gen. pi. p. 891) to Cyrhasium, the rebeing a prior Cristatella in Zoology; but 

 this is not, in the present state of the science, a sufficient reason for the change.
