Species 1, Dalmatis incola. JWalp. Ann. iii. 898. Reich. Tc. Fl. Germ. t. 1927.—Genus charae- 
teribus earpologicis Caucalineis accedit, sed habitus omnino Seselios et juga secundaria, etsi pro- 
minula, multo minus valent quam primaria. A4£hamanta densa, Boiss. Diagn. Ser. 2. v. 98, cum 
A. ramosissima (Portenschlagia) comparata, nobis ignota est.

Genus ab auctoribus in sectiones 4 imprimis ex involucro dividitur, inter quas HIPPOMARATHRUM, 
olim in Fl. Wetter. ex DC. Prod. iv. 144, et nuper a Schurio in Enum. Pl. Transsylv. 256 pro 
genere proprio involucellorum bracteis basi connatis propositum est ; et LipaworIS, Crantz, Stirp.

ribus generice distinguitur caule elatiore, foliis amplius decompositis, involucro co-bracteato et 
calycis dentibus magis evolutis. Involucrum tamen sepe deest in 5. /ibanotide ct calycis dentes non 
longiores quam in S. dichotomo aliisque e sectione Euseseli. 
In S. dichotomo, Bieb., vitte vix dimidio fructus longiores sunt, in S. Zeucospermo tenuissima, 
S. gummiferum, Sm., S. petreum, Bieb., speciesque affines, incluso LowAToPonto, Fisch. et Mey. in 
Bull. Phys. Math. Acad. Petersb. iii. (1845) 306 (in quo Bunge rite vittas solitarias observavit), 
distinguuntur fructu oblongo hirsuto, jugis minus prominentibus. 
ScAPHESPERMUM, Edgew. in Trans. Linn. Soc. xx. 08, Walp. Ann. i. 357, a SeseliLus fructu hir- 
suto preditis non differt nisi fructu paullo latiore quam in plerisque speciebus. Habitu Eiocycle 
nude, Lindl. (quee Pituranthi species), accedit sed fructus forma valde diversa.
