MR. J. BALL’S SPICILEGIUM FLOREZ MAROOOANS. 851 
PotyGaLa WesBIANA (Coss. in Bull. Soc. Bot. Fr. xx. 240). 
Descriptionem cel. auctoris preeferre juvat. 
“Planta perennis, ut videtur a basi ramosa, ramis diffusis, teretiusculis, 
inferne denudatis pulvinis foliorum delapsorum tuberculatis, superne 
dense foliosis, pilis arcuato-ascendentibus dense pubescentibus. Folia 
eodem modo ac rami sed parcius pubescentia, oblonga, plana, in 
petiolum contracta, acutiuscula vel inferiora obtusa haud mucronata. 
Flores majusculi, in axillis foliorum superiorum in racemos brevissi- 
mos cymiformes 2-3-floros vel se@pissime abortu unifloros dispositi, 
bracteolis 3 membranaceis obovatis amplis deciduis ad basim pedi- 
celli involucrum efformantibus suffulti. Sepala omnia citius decidua, 
glabrescentia, 3 exteriora albida membranacea vix herbacea quorum 
“superius majus fornicatum subsaccatum et duo inferiora planiuscula 
ovata, 2 interiora petaloidea alba vel pallide purpurascentia corollam 
subzequantia obovata obtusa inferne angustata. Petala 3, inter se et 
cum vagina staminali ad tertiam partem superiorem in tubum superne 
fissum coalita, duorum lateralium limbo inzequilatero concavo-subeari- 
nato pallide purpurascente apice obtuso, inferioris limbo zquilatero 
concavo-carinato genitalia amplectente apice truncato in carina pro- 
cul ab apice ecrista purpurascente in Jobos nonnullos oblongos latius- 
culos haud incrassatos divisa donato superne pallide lutescente. 
Ovarium superne basi glandula stipatum. Capsula (immatura tantum 
visa) membranaceo-carnosula, a latere compressa, obovata, apice mar- 
ginata.” 
Mar. sept.—Florentem legimus in monte Beni Hosmar supra Tetuan 
ubi eam olim legit P.B. Webb!; et iterum spec. 2 detexi in rupibus 
juxta urbem Tetuan! In monte Djebel Moussa supra fretum Her- 
culis eminente legit cl. Blackmore. 
Monente cel. Cosson :—“P. Webbiana, floribus maguis, in racemos axil- 
lares 1—3-floros dispositis, sepalis deciduis, superiore fornicato subsac- 
cato, crista carinali petali inferioris parce et grosse lobata, ad sectionem 
Chamebuzus pertinet—A P. Munbyana (Boiss. et Reut. Diagn. 
Pl. Or.’ ser. 2, v. 50) differt ramis teretiusculis, non acute angulatis, 
dense pubescentibus, non glabrescentibus, foliis haud mucronatis, 
petalis lateralibus haud truncato-obtusis—A P. Chamebuzo, L., cui 
valde affinis, distincta indumento ramorum densiore, foliis minus cori— 
aceis haud mucronatis, petalis lateralibus haud truncatu-obtusis, lobis 
cristee tenuibus planiusculis, non incrassatis subcorculatis.” 
Facie simillima est P. Chamebuzo, var. rhodoptere, stirpi Alpium Vene- 
tarum solenni, sed in hac, preter notas supra indicatas, sepala in- 
teriora saturate purpureo-rosea, petala lateralia apice lutescentia ; 
dum in P. Webbiana, sepala interiora in viva pailide purpurascentia, 
petala lateralia lete purpureo-rosea. Folia in P. Chamebuzo longiora, 
angustiora, nec sensim in petiolum attenuata. 
P. Chamebuaus est Alpium Europe (latiore sensu) incola, unde in eri-
