399. Sagina nodosa Fenzl var. monilifera Lange. See 
Ascherson and Graebner, Flora des Nordostdeutschen Flacldandes, 
30 and 843, 1898. 
In this plant the leaf-axils of the lateral stems develop fascicles 
of small leaves, which drop off and readily take root in suitable 
conditions. This peculiar modification seems to be more readily 
induced in hare wind-swept places and the writer has in his herbarium 
illustrative examples from Braunton Burrows, N. Devon 4 ; North 
Warborough, Hants 12 ; Marcham, Berks 22 ; Port Meadow, 
Oxford 23; Near Yarmouth, Norfolk E. 27; Barmouth, Merioneth 48; 
Aberfraw, Anglesey 52 ; Southport, Lancashire 59, Portumna, Clare, 
Galway, North Bull, Dublin and Gweedore, Donegal. 
403 (2). Sagina glabra Koch Syn. 439, 1842 var. scotica nov. 
var. Ben Lawers, Mid-Perth 88. 
Planta elongata, foliis filiformibus, subaristatis, axillaribus 
fasciculatis, pedunculis solitariis puhescentibus cernuis, petalis 
calyce duplo longioribus. Habitu laxo, extenso floreque magno, 
folia omnia elongata. 
The above plant differs from 5. saginoides, with which it has 
been confounded, by the more creeping growth, longer petals and 
smaller capsule. The subligneous root stock and creeping-decumbent 
habit distinguish if from ^S. subulata, while the pentamerous flowers 
and long petals separate it from S. procnmbens. From typical 
5. glabra the above plant differs by its smaller and slightly 
shorter capsules. Professor Graebner thinks my suggestion as 
to the name it shall bear a very probable one, but we await 
Professor Schroeter’s report on his examination of it with much 
interest. 
The writer has a similar plant from Glen Callater, S. Aberdeen¬ 
shire, and others exist in the Herbarium at Oxford, labelled 5. 
Linncei from Ben Lawers, and a sheet of it collected from the same 
mountain by Professor Babington at Cambridge was first labelled 
5. procumbeus and then altered to S. saxatilis (=S. Linncei=S. 
saginoides). 
488 var. Geranium Robertianum L. var. villarsiannm (Jordan 
in Cat. Grenoble, 1849) as a species=G. purpureum Vill. FI. Dauph. 
iii., 374, t. 40 pro parte. This differs from G. modestum and G. 
purpureum by its prostrate growth, by its smaller size, its usually 
green flatfish leaves and slight odour. Specimens from the 
calcareous district of Ballyvaghan are almost identical with Jordan’s 
type, which by the kindness of Dr. Moss I have been enabled to 
examine in the Cambridge Herbarium. Jordan’s description is 
appended:— 
“ G. pedunculis bifloris, inferioribus folia vix aequantibus, sepalis 
dense glanduloso-hispidis dorso convexis late costato trinerviis latius- 
cule membranaceo-marginatis aristatis, petalorum limbo parvo laete 
purpureo oblongo-obovato unguem suum fere a basi anguste alatum 
cequante , antheris flavis orbiculato-bilobis stigmata pallide purpurea 
vix aequantibus, fruetus rostro 4-5 lin. (10-12 mm.) longo, carpellis 
mox deciduis rubellis glabris dense rugoso-costatis, rugis superioribus
