15. G. arctophila (Griseb.); caule humili basi in ramos cauli similes divLso superne sini- 

 plici triflori, foliis obscure 3-nerviis, imis obovato-oblongis basi attenuatis, caulinis ovato- 

 oblongis acutis, sepalis margine scaberrimis vix basi junctis insequalibus, majoribus corolla 

 tubo brevioribus, corollae 4-fido3 cEerulese lobis ovato-triangularibus basi supcnncumbenti- 

 bus acutissimis setula terminatis (margine laevibus) tubo ex basi lata sensim sequaliter am- 

 pliato triplo brevioribus. (Tab. CXLIX.) — ^. densiflora; floribus tribus terminalibus ap- 

 proximatis, foliis caulinis cordato-ovatis 1. cordato-lanceolatis obtusiusculis, sepalis duobus 

 maximis corollee tubum aequantibus 1. superantibus, minoribus anguste lanceolatis abbrevi- 

 atis. (The colour of the flowers is, perhaps, also different, since all the corollse of this 

 variety have kept their bright blue, as the colour was stated by Mr. Drummond; while 

 the specimens from the Arctic sea-coast have now whitish flowers, with a violet tint here 

 and there.) Tab. CXLIX, B.B. 



Radix tenuis, simplex, curve descendens. Caulis basi infra ramificationem foliis quibusdam rosulatus; 

 rami insequales, partim decumbentes, partim descendentes, medius plerumque major erectiusculus 2-3un-

 obovato-oblonga obtusa 1. elliptico-oblonga acutiuscula, margine ad lentem tenuissime serrulata, (6-8'" 

 longa, 3'" lata;) caulina supra medium ramura sita, ovato-oblonga, sessilia, acuta, sjepe acutissima, (6-9"' 

 longa» 2-4'" lata.) PedicelU laterales ex axillis foliorum caulinorum 2-G'^ longi; pedunculus terminalis 

 8-12"-longus, ebracteatus. Calyx fere ad basin divisus, sepalis foliis caulinis simillimis. Corolla ^exa

 Anlherm parvae, oblongae, violaceas, incumbentcs. Ovarium oblongo-lineare, stamina coroUteque tubum 

 sequans. AS^wifl^a 2 oblongo-linearia, revoluta, ovario imposita, quam in ceteris Arctophilis longiora.
