different temperatures above the boiling point, may enable us to take 

 a further step in this inquiry, and to ascertain whether lignose is a 

 mixture or a homogeneous substance. And we may then hope to 

 obtain by other methods of research some insight into its chemical 

 constitution and its physiological production.

Vcrhascum calycimim, nob. — Planta tota albo-floccosa ; caulis 

 florifer circa bipedalis, subsimplex vel breviter ramosus ; folia in- 

 feriora obovato- acuta, in petiolum attenuata, caulina sessilia, superiora 

 angustiora, floralia lanceolato-linearia, omnia, vel saltern inferiora, 

 glomerulos florales superantia ; flores pedicellati, pedicellis calycem 

 subaequantibus ; calycis segmenta oblongo-linearia, pro gene re longis- 

 sima, capsulam ovoideam sat magnam aequilonga vel superantia ; 

 stamina inajqualia ; filamenta purpureo-barbata. Ab affinibus (e § 

 Thajjsoidea, Benth. in DC. Prod.) calyce et foliorum forma bene dis- 

 tincta. Legiraus in regione inferior! Atlantis Majoris, in convalle Ait 

 Mesan et prope Sektana ! 



Verhascum, nov. sp. ? V. ITooIceriamim, nob. MSS. in Herb. 

 Kew. — Descriptio ex speeimine unico a eel. J. D. Hooker lecto in 

 regione inferiori Atlantis Majoris, in convalle Urika. Bienne (?), 

 caulis bipedalis, ramoso-paniculatus ; folia dense pannosa, tomento 

 flavo obtecta, nervis in pagina inferiori valde promiuulis, inferiora 

 elliptico-lanceolata in petiolum attenuata, caulina sessilia ovata acutius- 

 cula ; flores parvi ; calycis segmenta abbreviata, tomento detersibili 

 interdum virescentia ; capsula ovato-conica obtusa dimidio breviora ;

Plantae nostrce proximum est V. Jernacha, Hochst. MSS. in A. 

 Richard Tent. H. Abyss., ii.,108. — Hoc tamen osteudit stamina multo 

 breviora, subaequalia, et capsulam ovoideam. Yix cum stirpe maroccana 

 conjungenda, sed in hoc genere ratio specierum valde incerta. Cel. 

 Bentham in DC. Prod , vol. x., citat V. Jernacha, Hochst. (ex MS. 

 Hochstetteriano ?) et dubitative—dum flores non vidit — sub V. phlo- 

 moides collocavit.

 ter pilosa, vix aut ne vix viscida ; folia variabilia, inferiora sublyrato- 

 pinnatifida, vel elliptico-spathulata lobato-incisa, margine crenato- 

 serrata, caulina oblonga, grosse inciso-serrata, superiora sensim decres- 

 centia non bracteiformia ; pcdicelli calyce ter longiores, demum rigidi ; 

 calycis segmenta acuta, medium versus serrulata, ex basi styli persis-
