RAOULIA. 



pans of R. parnassifolius (and yot more copiously in the drier scree 

 beyond) do there seem any traces as yet of any offspring. 



R. sericophyJlus is an alpine from the South Island of New Zealand. 

 The whole growth is clothed in silky wool, and the leaves are all at the 

 base, broadly oval and then feathered into three cloven leaflets. 

 The naked stems are some 2 to 8 inches high, bearing big golden 

 flowers about 2 inches across. 



R. Sommicri is a 4-inch yellow-flowered species of the Caucasus. 



R. Thora has been pictured under R. scutatus, its amplified form. 

 The typo is smaller and slenderer, a mean and venomous worker of 

 iniquity — filled with an intensely poisonous nature, and found often in 

 the lower woody and rocky places of the Southern limestones. It has 

 many varieties, of which R. dubius has also been called R. hybridus 

 (not our R. hybridus, Biria, which should be R. Thorax R. brevifolius) ; 

 there is also R. carpathicus, which is the same as R. Tatrae (Borbas). 

 As for R. Pythora (Crantz), this is clearly R. brevifolius, Ten. 



R. Traunfellneri is a sub-species of R. alpester, and in Switzerland 

 (where it is very rare), can only with the greatest difficulty, if at all, 

 be distinguished. Its real range, however, is through the high 

 limestones of the Eastern Alps, and then again in Transylvania. It 

 may be known by its much smaller, slighter habit, and duller leaves, 

 more finely cleft into narrower, divergent, and much less veiny 

 segments. And the 2- to 3-inch stems never carry more than one blossom. 

 It may be seen in fine character round the snow-patches high on the 

 Grigna, almost its last westerly extension, and is a dainty miniature 

 of dainty R. alpester, of the same needs and the same charm. 



R. Traversii is a cream-coloured variety of R. Lyallii, q.v. 



R. uniflorus is a garden form of R. montanus, q.v. 



R. Villarsii is a wild and high-alpine form of the same, dwarf, 

 and with flowers of notable size and brilliance. 



Raoulia.— A little race of creeping small mats from Tasmania 

 and New Zealand, not of any startling effect, even in foliage, but 

 useful for running over the surface of warm soil, sand, or moraine, 

 and acting as a carpet. There are innumerable species ; RR. glabra, 

 subsericea, Hectori, eximia, tenuicaulis, Haastii, Monroi, Buchanani, 

 rubra, mamillaris (these threo last form specially dense, hard masses). 

 R. subulata is a tiny mossliko thing, in patches of a few inches ; and 

 R. grandiflora makes fine sheets of shoots clad in overlapping little oval- 

 pointed leaves, stiff and silvery with close-pressed wool, each shoot 

 ending in a head of flowers frilled with white radiating bracts, about 

 two -thirds of an inch across, all the flowers of Raoulia being of 

 the same kind as in Helichrysum, to which the race stands close.
