Paroica pusilla, magn. C. divaricatcB, acro-et cladocarpa pallide viridis, 

 apicibus florentibus saspe purpiirascens. Caules breves fragiles, ra- 

 mique (pauci) prostrati radicellosi, apice assurgentes, aliis ramis elon- 

 gatis minutifoliis, nullo flagellari radicante. Folia inferiora — ramorum 

 sterilium praecipue — distantia minuta cuneata, superiora, flores versus, 

 imbricata cuneato-quadrata vel subrotunda, omnia subcarinata, fere vel 

 usque ad ^ acute biloba, lobis ovato-triangularibus acutis; cellulcB i^ar- 

 vulse subpellucidse subelongatae 4 — 6-gon3e, ad angulos vix incrassatae. 

 Foliola duplo breviora, inferiora linearia lanceolatave, superiora ovato- 

 lanceolata raro apice fissa. Involucra ovato-julilormia ; bractecB 3 — 5- 

 jugse, foliis sat majores, oblongo-orbiculatae concavse minus profunde 

 bilobae, xalus minus denticulatse, antlieridium singulum foventes, intimae 

 (mediante bractea postica, lateralibus paulo minore) in excipulum alte 

 connatae. Perianthia bracteis duplo longiora oblonga vel ovato-oblonga

Hah. Germany: near Custrin, in fine fruit, Sept. 1833 (Flotow); on 

 sandy paths in woods near Salem, Baden, in fruit, July, 1873 (jack); by 

 the railway near Beutsch- Landsherg in Styria — young plants, purely cT, 

 May, 1875 (limpeicht). 



Obs. Jack's specimens are more slender and longer, and the perianth often lineari- 

 elongSte; but in foliage and inflorescence they accord with* Flotow's specimens, al- 

 though in both there occur occasionally purely male plants, with the andrsecia oc- 

 cupying the medial portion of a stem or branch. The Deutsch-Landsberg plants, so 

 far as I have examined them, are solely males : very young, with mostly unbranched 

 stems; the andraecia occupying their upper half, and sometimes topped by a tew 

 normal anantherous leaves, but never by a female flower.
