at the edge, the outer deltoid, the^ inner lanceolate. Florets 12-15 

 to a head. Achenes quadrangular, glabrous, pale brown, -^ inch long. 

 Pappus 2^ lines long, of two rows of whitish flexible bristles, the 

 outer about a quarter the length of the inner. Corolla not seen. 



Hab. — Rio Janeiro, Glaziou, 7625! Only near P. macropoda, from 

 which the loose brownish woolly pubescence of the branchlets marks 

 it at a glance.

{Continued from page 111, and concluded.) 



Paronychia macrosepala, nob. — Perennis ; caules numerosi prostrati ; 

 folia oblongo-ovata, acuta, dense pubescentia, demum patulo-recurva ; 

 stipules lanceolatae, longiuscule acuminatae ; bracteae ovato-lanceolatae, 

 abbreviat93, sepalis vix sequilongoe ; sepala foliacea, oblongo-linearia, 

 obtusa, mutica, valde inaequalia, apice plus minusve recurva, etiam in 

 prefloratione basi discreta ; petala (vel staminodia?) minima linearia ; 

 stylus brevis, profunde bifidus, ramis stigmatosis divaricatis ; stamina 

 brevissima, ima basi disco calycino adnata ; antherae breves. 



Hand raro in provinciis meridionalibus, tam in planitie ' (Ain 

 Oumast !, Mesfioua !, juxta urbem Marocco !) quam in regione inferiori 

 Atlantis Majoris (Ait Mesan !, Seksaoua!). 



Pianta nostra in § Anoplonychia,'FQnz\., collocanda, P. capitate^, 

 Lam., affinis, sed bene distincta. Haec est certe species polymorpha 

 cui, suadente eel. Fenzl in Led. Fl. Ross, ii., 163, jungendae sunt 

 Jllecehrunr cephalotes. M.B., et P. nivea , C.A.M. ; nee mihi satis dis- 

 tincta videtur P. nivea, DC. Huic velut subspecies proximo se- 

 quuntur P. arctioides, DC, et P. serpyllifolia, DC. Species nostra ab 

 his omnibus dignoscitur sepalis (v. calycis segmentis) angustioribus 

 valde inaequalibus, adeo ut sep. maximum minimo duplo longius est, 

 reliquiis intermediis, nee subaequalibus, fructiferis subrecurvis, nee 

 clausis ; bracteis et antheris fere duplo minoribus ; et denique stylo 

 breviori. 



Insuper in Paronycheis e grege P. capitatce video sepala, praesertim 

 in facie interna, insigniter nervosa, dum in nostra nonnisi ima basi obso- 

 lete nervosa sunt. 



var. Querioides, nob. Bracteis brevioribus, foliis 



velutinis rigidiusculis approximatis, insigniter recurvis a typo recedit, 

 et facie Queriam hispanicam simulat. 



Specimen unicum legi in Convalle Ait Mesan ! 



Rumex vesicarius,L., xar. rhodophysa, noh. — Differt a typo radice 

 bienni, anno primo caules plurimos breves emittens. In his racemus
