﻿Out of this total, several are plants introduced into Britain, and a 

 few seem to be recorded by error, e. g., Primula elatior Jacq. 

 (Morgan), and Polygonum maritimum Linn. (Morgan and Lees). 



Morgan's Flora Ceretica Superioris includes a radius of sixteen 

 miles from Aberystwith, thus comprising nearly all the area explored 

 by us ; but only in few cases do our localities for the less common 

 species coincide with his. It is curious, considering how distant 

 the journeys made evidently were, and how he investigated " in 

 the autumn of 1848 and the spring and summer of 1849," that he 

 records so few stations for common plants ; thus, Montia fontana 

 and Callitriche only for Llanbadarn ; Scabiosa Succisa only for 

 Constitution Hill. Many other instances might be given showing 

 that, however accurate, Morgan's Flora cannot be regarded as 

 approaching completeness. 



It is not intended here to give a full list of the plants observed, 

 — such information we hold at the service of any botanist who may 

 desire it ; but the following contains what in our eyes seems of the 

 most importance. Signs used : — 



* Species hitherto unrecorded for the county. 

 (*) Segregate species, apparently noted, but under an aggregate 



+ Species not recorded for the county in Watson's Topographical 



Botany, but mentioned by other writers. 

 [ ] Aliens not likely to hold their own for long. 



(*) Ranunculus hederaceus L. Abernant. — b. omiophyllua Ten. 

 Pont-rhyd-fendigaed. — R. Flammula L., b. pseudo-reptans Syme. 

 On the shore of several llyns. 



t Aquilegia vulgaris L. Roadside near Henffordd Arms, probably 

 an introduction. Cf. Report, Scientific Society of Univ. College, 

 quoted above. 



+ Meconopsis cambrica Vig. Devil's Bridge ; Nant Bhyddnant ; 

 a rare plant in this district. 



Chelidonium majus L. Common in the Rheidol Valley from 

 Capel Bangor to Pont-pren-plwcca ; Strata Florida Abbey. 



*Fumaria pallidifiora Jord. Ty-llwyd-isaf ; Goginan; Ty Cam; 

 Llanbadarn. — F. confusa Jord. Near Henffordd Arms ; near Glan 

 Rheidol ; Capel Bangor ; Llanfihangel Lledrod. 



* Subularia aquatica L. Llyn Hir ; Llyn Egnant ; Llyn Gynon. 



* Brassica Rapa L. Henffordd Arms ; Ty Cam ; Llanfihangel 

 Lledrod. 



* Raphanus Raphanistrum L. Not unfrequent in the hills up to 

 1020 ft. 



* Viola Reichmbachiana Bor. Fairly common.— f V. tricolor L. 

 Yspytty Cynfyn ; Castell-fan-grach.— t V. arvmsis Murr. Yspytty 

 Cynfyn.— V. lutea Huds. The type and the form amoena Syme are 

 both abundant. Our highest and lowest records are at 1640 and 

 630 ft. 



(*) Polygala serpyllacea Weihe. Common in the hills. 



tiilene maritima With. We traced this species from Aberystwith 

 up the Ystwith river to a point, Nant Cwm Du, sixteen miles in a 

 straight line from the sea, at 800 ft. It grows on the rocks at the
