an important landmark from the phyletic standpoint in that it 
indicates the origin of Aquilegia. Une species, S. Henryi, points 
in its vegetative characters rather to Hnemion or even to Coptzs. 
Aquilegia Jonesit, Parry in Amer, Nat. vin. 211 (1874), a 
native of the Northern Rocky Mountains, illustrates the intricacy 
of these intergeneric relations very clearly; the floral whorls are 
manifestly those of Aguilegia, and although the general habit is. 
diverse from the majority of Columbines, it is approached in 
A. nivalis, Falconer, while the foliage and shrubby lower stem 
are just as characteristically those of Paraquilegia. 
At pp. 54-55 of the Illustrations, Royle has described two 
species from Upper Kanawar, and depicted them in figs. 8 and 4 
on Plate 11, as Lsopyrum grandiflorum and Lsopyrum microplyl- 
lum- respectively. Hoyle’s figure 3 seems to approach J. caespi- 
tosum of Boissier and Hohenacker, Diagnoses ser. (1) fasc. viii. 7 
(1849), of which we have seen an authentic specimen at the 
Natural History Museum. 
n deference to the authority of Maximowicz and of Franchet 
we have retained the three species. just mentioned, although 
after close examination of a large suite of specimens we are unable 
to distinguish them satisfactorily in the Herbarium. 
With these, which are all of a habit peculiarly adapted to the 
inhospitable spots in which they grow, we have associated a 
th, which in general appearance inclines towards Zsopyrum 
proper, but in the form and arrangement of the follicles to 
Suliman Range at high elevations, from the Alatau, where it 
was discovered in 1841 by Karelin and Kiriloff,* and described by 
them in Bull. Soc. Nat. Mosc. xv. 135 (1842) as ‘‘Zsopyrum 
anemonoides’’: this name being open to objection, we have 
exchanged it for (Paraquilegia) uniflora given (under Isopyrum) 
by Hemsley to Afghanistan specimens (Journ. Linn. Soc. xix. 
p- 149 publ. 1882). 
Paraquilegia is essentially a Central Asian type; even P. micro- 
phylla, which has by far the widest range of the three shrubby 
forms, is not found much to the south of the watershed that
