Candollio adseriptum, differt petalorum forma et fructus margine loculo seminifero contiguo absque 
spatio hyalino. . Fructus fere Tordylii sed habitu petalisque facile distinctum. 
133. Zosimia, Hoffm. Gen. Umb. 145. t. 4.—Calycis dentes prominuli. Petala obovata; 
acumine inflexo, ob costam superne impressam orasque plus minus dilatatas emarginata 
v. biloba, szpe inzqualia. Discus depressus, margine undulatus, stylis in| medio non 
inerassatis (v. rarius stylopodia conica P). Fructus orbieularis v. elliptico-oblongus, plano- 
compressus, margine latiuseulo tumido ante dehiscentiam integro cinctus ; carpella medio 
dorso leviter convexa; juga dorsalia et, intermedia tenuissima, lateralia in alas dilatata, 
arete contigua, marginem fructus formantia, spatio inter marginem et loculum semini- 
ferum hyalino; vitts& ad valleeulas solitarie, magne, intrajugales tenuissime, plus minus 
eonspieus.  Carpophorum bipartitum. — Semen planum v. dorso leviter convexum.— 
Herba perennis, pubescens v. hirsuta, caudice crasso. Folia pinnatim decomposita, 
laciniis: parvis. Umbelle composite, oc-radiate. Involueri et involucellorum bractese 
sepius oo, parve. Flores albi v. pallide flavo-virentes, petalis eequalibus v. inzequalibus, 
rarius late radiantibus. Ovarium pubescens v. hirsutum. 
Species 1, per Asiam occidentalem ab Affghanistania usque ad Caucasum Arabiam et regionem 
Sinaiticam late dispersa. DC. Prod. iv. 195 (excl. Z. anethifolia ad Ducrosiam relata). Sibth. Fl. 
Gr. t. 281 (ZTeracleum).. Planta quoad habitum Duecrosic affinis, floribus Heraclei v. Tordylii ; fructu 
ab illo differt margine tumido, ab hoc spatio intra marginem hyalino. Ceterum magnopere variat 
involuero magis minusve evoluto, petalis regularibus v. plus minus irregularibus, et fructus forma 
nune orbiculari nunc fere duplo longiore quam lato. i

tatem Z. absinthifolie reducenda. Z. anethifolia, DC., est Ducerosia. — '

plicato-rugoso v. rarius lavi cinctus ; earpella vix dorso convexa; juga primaria dorsalia 
et intermedia tenuissima v. inconspicua, lateralia inerassato-dilatata, arcte contigua, mar- 
ginem: fructus formantia; vittz» ad valleculas solitarie v. rarius oo. Carpophorum bipar- 
titum. Semen complanatum.—Herbs annus, pubescentes hirsutze v. tenuiter lanats. . 
Folia nune indivisa, subeordata, dentata, nune sepius pinnata, segmentis latiusculis den- 
tatis incisis v. rarius dissectis. Umbelle compositze, nune inzqualiter pauciradiate, nunc 
regulariter co-radiate. Involucri et involucellorum bractes lineares, nunc flores exce- 
dentes, nune. minimz v. presertim involucri obsolete. Ovarium strigoso-pubescens v. in -
