 Jvuicus arcuatus. Wald. Fl. Lap. p. 87. 



Subcaispitose, with rather long stolons. Stems solitary. Radical 

 leaves very narrowly linear, tapering most towards the apex, chan- 

 nelled, recurved, thick and firm, clothed at the margins only near 

 the base of the leaf with a few soft caducous hairs; stem with 1 or 

 2, similar to the radical ones, but smaller. Flowers in small sub- 

 globular spikes, few, rarely more than 3 to 5 in each spike. Spikes 

 few, in a subumbcllato-coryrabose panicle ; lower spikes supported on 

 capillary recurved peduncles, which are simple or once cymosoly 

 branched at the apex ; uppermost spike subsessile. Bracts narrowly 

 lanceolate, acute, sparingly ciliated at the apex. Perianth leaves lance- 

 olate, acute, a little longer than the capsule, pale brown with narrow 

 pale margins. Capsule subglobular, trigonous, very shortly and 

 abruptly acuminate-apiculate. Seeds oblong-ovoid, dark brown, 

 without an apical crest, but with a very minute indistinct pale basal 

 caruncule. 



On stony debris on the tops of high mountains. Very local. Plen- 

 tiful on the tops of the Cairngorm ^lountains, on the confines of Aber- 

 deen, Banff, Inverness ; Cairn-Towl, Ben-mac-Dhui, Braeriach, and 

 more sparingly on Ben Avon, also near the summit of Loch-na-Gar, 

 Aberdeenshire ; and, according to Dr. Graham, in Sutherland on the 

 summit of Fonniven, and also on the ridge leading to the top of Ben 

 More, Asynt, ascending from Inchnadufi^. 



Scotland. Perennial. Late Summer, Autumn. 



Plant growing in loose tufts. Leaves 1 to 3 inches long, leathery 

 in texture. Stems 2 to 6 inches high. Lowest peduncle 4^ to 2 inches 

 long. Perianth leaves \ inch long, nearly concolorous, the pale 

 margins being very narrow. Filaments nearly as long as the anthers. 

 Capsule pale reddish-brown. Seeds considerably smaller than those 

 of L. campestris and L. multiflora, and with scarcely any caruncule 

 at the base. Panicle branched like that of the Mcwimco group, but 

 the individual spikes are much more similar to those of the Congestce, 

 with which it is still further connected by Arctic L. hvperborea,

Curved Alpine Woodrush.
