55.—Calycis dentes obsoleti. Petala anguste cuneata v. oblanceolata, acumine inflexo, 
ob costam haud impressam integra. Discus: stylopodia coniea v. angustissima, basi haud 
dilatata. Fructus obovato-oblongus, plano-compréssus, ala apice sinu profundo angusto 
emarginata cinctus ; earpella dorso leviter convexa ; juga primaria dorsalia et intermedia 
filiformia, parum elevat: lateralia in alam tenuem expansa, arete contigua, fructus alam 
ante dehiscentiam integram formantia; vitte ad valleculas solitarim, intrajugales non- 
nunquam tenues, plus minus conspieug. Carpophorum bipartitum. Semen a dorso valde 
compressum, facie planum v. leviter biconvexum xnedioque suleatum.— Herbz» glabrz, 
perennes, elate. Folia ternato-pinnatim composita, segmentis paucis linceolatis elonga- 
tisve integris subdentatisve, inferiora nune indivisa. Umbelle composite, radiis coo gra- 
cilibus. Involucri bractez pauc:e, involucellorum oo, omnes tenues. Flores albi? 
Species 2, Africze tropics orientalis incole ; in altera (Z. abyssinica, Rich.) stylopodia angustissima 
infra medium connata basique constricta, et semen facie suleatum vidimus; in altera inedita e col- 
lectione Speke et Grant, Abyssiniese csterum simili, stylopodia crasse conica, libera, et semen facie 
planum. Speciminibus utriusque speciei jam defloratis, petala in paueissimis tantum floribus obser- 
vata. Genus ceterum Peucedanis tenuiter alatis valde affine, differt imprimis stylopodiis in sinu 
perangusto sepultis. ! 
197. Heracleum, Linn. TR n. 345. —Calyeis dentes obsoleti v. plus minus conspicui. 
. Petala euneata rhombea v. unguiculata, sepius insqualia, majora v. omnia acumine in- 
flexo, ob costam superne impressam orasque dilatatas emarginata v. profunde biloba. 
Diseus: nuno stylopodia éonica, margine undulato latiusculo v. fere obsoleto cincta, nune - 
circa stylos non inerassatos depresso-pulvinatus v. minimus. Fructus orbiculatus obovatus 
v. elliptieus, plano compressus, ala ante dehiscentiam integra plana v. disco haud crassiore 
cinctus, margine &z:pe nerviformi vix tumido ; carpella vix dorso convexa ; juga dorsalia et 
intermedia tenuissime filiformia, lateralia in alas expansa, arcte contigua alam fructus for- 
mantia; vitte ad valleculas sepissime solitariz, fructu breviores et versus extremitatem 
plus minus dilatats, rarissime usque ad basin attingentes, intrajugales etiam hine inde 
adsunt tenues. Carpophorum bipartitum. Semen plano-compressum.— Herbs perennes 
v. biennes, nunc altissimz, nune humiles, sepius plus minus pubescentes scabrz v. setoso- 
hirte; rarius glabre. Folia nune ampla latissime lobata, nunc pinnata v. pinnatim, rarius 
ternatim dissecta, segmentis latis lobato-dentatis rarius parvis. Umbelle composita, oo- 
radiatz, seepe amplae. Involueri bracteg nune paucze ssepius caduce v. 0, nune oo foliacez, 
involucellorum oo. Flores sspe polygami. Petala alba ochroleuca v. rarius flava, sspe 
radiantia, majorum interdum lobi late expansi, aeumine inflexo pluries longiores, in pluribus 
speciebus hirsuta. Ovarium sepissime pubescens, fructu interdum demum glabrato. Vittze 
commissurales scepe valde abbreviatze. 
Species ad 70, ab.auctoribus descriptse, plurimse tamen certe reducende et vix ultra 50 bone vi- 
dentur, regionum. temperatarum hemisphrerii borealis orbis veteris incole, una per Americam 
borealem late dispersa; nonnulle in montibus Indis orientalis et Abyssinir crescunt. DC. Prod,

Genus sat naturale, a Peucedano sepius habitu, petalis, ovario tomentoso fructus ala sepe mar- 
ginata, et vittis abbreviatis dignoscendum. —Vittze tamen interdum at rarius occurrunt abbreviatze 
in. Peucedano et elongate in Aeracíeo, ovarium rarissime in Heracleo subglabrum, petala in paucis 
speciebus nec alba nec radiantia, et habitus specierum minorum foliis pinnatis segmentis: parvis ei 
Peucedanorum popnaonum quodammodo accedit ; a JMalabaila distinguitur fructus margine 
minus incrassato. -

Togprrurorsis, DC. Prod. iv. 199, est -Heraclei species involucro magis evoluto et floribus ample 
radiantibus insignis. Fructus, Candollio ignotus, omnino Zeraclei est.
