Notes on the Illustrations in this Issue. 
Eryngium Oliverianum. 
One of the species of Eryngium that has attained consider¬ 
able popularity within recent years is that under notice. It 
is often spoken of under the name of E. amethystinum, but the 
latter is a much dwarfer plant and more difficult to grow. No 
doubt one of the reasons for the popularity of E. oliver ianum 
is that it lias proved of easy cultivation in the South. It 
takes the place in southern gardens which E. alpinum takes 
in the North. We may calculate, therefore, that it is better 
adapted to withstand a dry atmosphere than its congener of the 
Alps, which loves the cool and moist atmosphere of Scotland, 
and may be grown in cottage gardens without any attention 
whatever, whereas in the South it is alwtays an unsatisfactory 
plant, appearing to be of weak constitution and very poor in 
colour. 
The plant under notice grows to a height of 3ft. or 4ft., 
branches freely, and produces numerous heads of large size. 
The bracts surrounding the heads and the stalks themselves 
size care should be taken not to cut into the centre of the root¬ 
stock of the main plant. If numerous pieces are wanted the 
gardener may carefully remove them with a knife, and those 
which do not bear roots may be inserted in light, sandy soil in 
pots or boxes and placed in a cold frame till they form roots 
and become established. Plants may also be raised from seeds 
which usually ripen in fair quantity. 
Saxifraga squarrosa. 
The species of Saxifraga are very numerous and develop into 
a great number of strikingly distinct for ms . Some of them 
are quite of miniature dimensions alongside of the stronger 
ones, which may be regarded as the giants of the family. That 
which we have under notice on the present occasion is one of 
the pigmies. As shown in our illustration the plant stem and 
flower are of very miniature dimensions, and actually range 
form liin. to 2in. in height. In the foreground will be seen 
two cushions or clumps of plants', each made up of a number 
of very small rosettes, consisting of tiny, pointed, three- 
cornered leaves, the whole being very densely arranged and 
compact, forming a miniature caesious or gray cushion. The 
Eryngium oliverianum, with steel-blue Bracts and Flowers. 
are more or less of a steel-blue colour, and the flower heads 
themselves are also deep blue and notable for thei^ size by 
comparison with the several other species usually seen in 
southern gardens. The lower leaves are divided nearly to the 
base, and are again more or less lobed and cut. The upper 
leaves are equally as deeply divided, but their segments are 
very narrow. The divided leaves form one of the best marked 
distinctions between this species and E. alpinum, and by that 
means .alone any gardener can readily distinguish between the 
two, even although he has not botanical knowledge. Our illus¬ 
tration shows all these broad distinctions, so that, readers can 
readily follow our remarks. The photograph from which it was 
prepared was taken by Mr. Charles Jones, The Gardens, Ote 
Hall, Burgess Hill, Sussex. 
Any light, friable soil which the roots can penetrate deeply 
vill meet the requirements of this species. Propagation may 
be effected by division of the plant, but unless it is of large' 
flower stems bear from Wo to five flowers in a cyme, and are 
unusually large, for so small a plant. The flowers are white 
and produced in great abundance, so that well-flowered cushions 
form a pretty picture on the rockery, which is its proper 
position. Our photograph was taken on the rockery at Kew 
in June last, when the plant was in bloom. 
Lilium pyrenaicum. 
One of the most familiar Lilies in old-fashioned gardens, both 
in rural districts and in towns, is that under notice. The 
flowers are similar in form to those of L. martagou, though the 
species is more closely allied to L. pomponium. They are deep 
yellow in the common form, marked with black specks. There 
is a yellow variety without spots, namely, the Martagon Iuteuin 
nonpunctatum of Parkinson, but there are intermediate forms 
in which a few spots only are present. The plant is of verv 
vigorous constitution, having its stem densely clothed with
