Gen. Umb. 202 (Tordyliun officinale, Linn., et T. apulum, Linn.), paullo magis discrepat jugis in 
pericarpio tenuissimo omnino inconspicuis et fructus disco vittis oo arcte approximatis oc-strinto. 
A Boissiero iterum generice separatur sed invita natura, et auctores fere omnes has species nunc in 
T'ordylio includunt.—Genus cseterum Ormosciadio cmterisque .Daucineis accedit fructus margine 
suberoso vix non e jugis secundariis potius quam e primariis oriundo, E 
135. Johrenia, DC. Prod. iv. 196, et Mem. Omb. 54. t. 1.—Calycis dentes tenues, 
sepius decidui. Petala lata, acumine lato involuto, ob costam leviter impressam retusa v. 
subintegra. Discus: stylopodia depressa, nune parva, nune dilatata, margine undulata. 
Fructus ovatus v. rarius suborbicularis, a dorso plano-compressus at crassiusculus, margine 
latiusculo erasso suberoso ante dehiscentiam integro cinetus; carpella dorso vix convexa ; 
juga primaria dorsalia et intermedia elevata, crassa, subsuberosa, lateralia crassiora et 
latiora, arete contigua, marginem fructus formantia; vitte ad valleculas angustas soli- 
tarie, tenues, nune obscurs, intrajugales rarius conspieusm.  Carpophorum bipartitum. 
Semen subplanum.—Herbs perennes, glabrae glauce v. rarius ad inflorescentiam pubes- 
centi-hirte, caudice crasso. Folia pleraque subradicalia, pinnatim decomposita, laciniis 
angustis parvisve. Umbelle composite, pauci- v. multiradiatm. Involucrum O0 v. oo- 
bracteatum, involucellorum bráctes oo lineares v. tenues, nunc parve v. subnulle. Flores 
flavescentes v. albi, non radiantes.

Ann. i. 954;.ii. 712. — Boiss. Diagn. Ser. 2. v. 99; vi. 80. 
Genus habitu nune Zosimice nunc Peucedanis nonnullis affine ; fructus margo crassus obtusissimus 
. Seselineas quasdam memorat, sed carpella dorso plana. Species Asis occidentalis floribus flavescen- 
tibus gaudent, et involucrum v. deest v. e bracteis parvis constat. In PmHLOIODICARPO, Turcz. in 
Ledeb. Fl. Ross. ii. 831 (ab auctore ad Libanotidem redueto in Fl. Baic. Dahur. i. 485), flores albi 
dicuntur et involucrum involucellaque magis evoluta sunt, ceterum tamen nec habitu nec floribus 
nec fructu à Johrenia differt,

pressus v. jugis inclusis sub-4-gonus, commissura latiuscula; carpella a dorso valde com- 
pressa, facie plana v. demum exsiccatione subeymbiformia ; juga primaria filiformia, vix 
conspicua, secundaria dorsalia ineonspieua, lateralia elevata, latissima, in lobos transversos 
suberosos eleganter divisa; vitte obscure. Carpophorum 2-partitum. Semen explana-
