* Calyx spreading; leaves divided.

8. S. granuláta (White Meadow Saxifrage).-Rootleaves kidney-shaped, with rounded lobes, stalked; stem leaves nearly sessile, acutely lobed; flowers panicled; capsule partly inferior. Plant perennial. The large milk-white flowers of this species are by no means uncommon during May and June on hedge-banks, meadows, and pastures, especially where the soil is of gravel. The root gives its name to the species, being what botanists term granulated, and consisting of a number of small reddish, downy, round tubers. It is a pretty plant, with slender leafy stems, ten or twelve inches in height. A double variety is a common garden flower.

9. S. cérnua (Drooping Bulbous Saxifrage).-Rootleaves kidney-shaped on long stalks, palmate and lobed; flowers solitary and terminal; capsule superior. Plant perennial. This species is now almost extinct on the only recorded British habitat. Its place of growth is on rocks on the summit of Ben Lawers. It is remarkable for having small reddish bulbs in the axils of its upper leaves. The white flower appears on the slender drooping stem in July, but the plant rarely blossoms, being mostly propagated by its bulbs.

10. S. tridactylites (Rue-leaved Saxifrage.) — Leaves wedge-shaped, 3-5 cleft; stem much branched; flowers terminal, each on a single stalk; capsule inferior. Plant annual. This little Saxifrage has small snowy-white flowers from April to July, on a stem two or three inches in height. It is very common on old walls, dry

barren heaths, and the roofs of cottages in England, but it is rare in the west of Scotland and in the Highlands. The petals are so small as hardly to extend beyond the calyx. The foliage is of a rich green, turning red after flowering. It is thickly set with short hairs, terminated with red globules, which render it very clammy to the touch. It is a very elegant little plant.

11. S. rivuláris (Alpine Brook Saxifrage).—Leaves 3-5 lobed, palmated, smooth, stalked; stem slender, branched, downy; flowers few; bracts oblong; capsule half inferior. This is a very scarce species, found in Scotland on moist rocks near the summit of Ben Lawers and Ben Nevis, but not in abundance. The only spot where it is known to occur plentifully is on Loch-na-gar, Aberdeenshire. The flowers are white, and the root perennial.

12. S. hypnóides (Mossy Saxifrage).-Barren shoots long, and usually prostrate; root-leaves 3-cleft, those of the shoots either undivided or 3-cleft, bristle-pointed, and more or less fringed; segments of the calyx pointed. Plant perennial. This is an abundant and most variable species, its leaves assuming so many forms that the varieties have been described as species under several names. The flowers are white, expanding from May to July, on rocky mountainous situations in England, Scotland, and Ireland.

13. S. cæspitósa (Tufted Alpine Saxifrage).-Barren shoots usually very short or wanting; root-leaves crowded, fringed, 3-5 cleft, with obtuse lobes; calyx segments blunt. In one variety the plant is larger, and in another smaller, but both without barren shoots. In this rare species the white flowers expand from May to

July. It grows on mountains, and is probably but another form of the variable Mossy Saxifrage, and, like that, it has a perennial root.

14. S. muscoides (Mossy Alpine Saxifrage).-Barren shoots very short, erect; root-leaves linear, blunt, and 3-cleft; stem few-flowered; calyx superior; petals short, scarcely longer than the sepals. Perennial. This plant, which is said to have been found in the Highlands of Scotland, is a doubtful native. It has buff-coloured petals, expanding in May.

15. S. geranoides (Geranium Saxifrage). - Barren shoots short; leaves downy and glandular, lower ones, and those of the shoots, on very long foot-stalks, deeply 3-cleft, the segments either cut or entire; calyx superior. Plant perennial. This Saxifrage is said to have been found on the Scottish mountains, but is a doubtful native.

2. CHRYSOSPLÉNIUM (Golden Saxifrage).

1. C. oppositifolium (Common Golden Saxifrage).Leaves opposite, roundish, heart-shaped, with rounded notches; flowers in small umbels. Plant perennial. This, one of our earliest flowering plants, is common by the sides of rivulets, and in wet woods. It is also frequent on some of the highest parts of the Highland mountains, near rills. Though a small plant it often grows in large quantities, and we have seen masses of it on bogs at Tunbridge Wells, looking quite beautiful as the sun shone on its small clusters of yellow flowers and yellowish green leaves, so that the plant was like
