Coiispectus specieriim. 
Sectio I. Platycoccus. Dissepiraenta fructus augustissima ; loculi a lateribus 
quam naaxime compressi, plani, dorso in cristam augustara a loculo ipso externe 
vix discretara producti ; flores pro genere majusculi; sepala exteriora et interiora 
quoad indumentum subaequalia; corpus lignosum compositum e centrali majore 
et periphericis minoribus 1 — 4, plerumque 3, in nna tantum specie (S. Ämpe- 
lopsis PI. ^a^ Lind.) corpus liguosum simplex; foliorum epidermis mucigera. 
Subsectio 1. Sepalum tertium et quiiitum a basi ultra medium coalita ; torus 
(instar illius Can^ios^^enm) elongatus, glandulis inferioribus obsoletis; rami 
trianguläres, rarius 5 — G-angulares, corporibus lignosis periphericis tribus. 
(Speeles brasilienses, S. communis Brasiliam ipsam traasgrediens.) 
A. Folia ternata (rarisshne transeuntia in biternata vel pleiie biternata in 
*S'. cuspidata Caiiib.) 
a. Rami (et folia) glabri (epidemiis valde mucigera) 1. S. tenuis Radlk. 
b. Rami toti pilis crispulis subadpressis hirti (epidermis sat mucigera) 
2. S. Regnellii Schlecht. 
c. Rami in angulis tantum jubato-pilosi (epidermis mucigera) 
3. o. cuspidata Camb. 
B. Folia biternata (cf. A, ob <V. cuspidatam Cariih.) 
a. Petioli omnes nudi 
aa. Rami 3 — 5-angulares, birsuti (folia subtus justa nervum medianum' 
hirsuta; epidermis mucigera) . . . . 4. S. hirsuta Canib. 
bb. Rami trianguläres, pubescentes (folia varie pubescentia vel sub- 
glabra; epidermis valde mucigera) . r>. S. communis Camb. 
b. Petioli partiales anguste alati (rami trigoni. glabri ; folia glabra ; epidermis 
valde mucigera) 6. S. stenopterygia Radlk. 
Subsectio 2. Sepalura tertium et quintum infra medium (S. canliospcy- 
moides, S. Ampelopsis) vel ima basi tantum vel omniuo non coalita; 
torus minus elongatus, glandulis inferioribus sat evolutis; rami 3 — 6-angu- 
lares vel teretiusculi ; corpus lignosum compositum e centrali majore et 
periphericis minoribus 1 — 4, plerumque 3, in una specie corpus lignosum 
simplex. (Subsectio minus naturalis, forsan inter alias Sectiones partim 
distribuenda. Speeles in America continentali per totam generis ditionem 
dispersae.) 
A. Corpus lignosum simplex (folia biternata ; sepalum 3 et 5 infra medium coalita ; 
epidermis mucigera; species novo-granatensis) 10. S. Ampelopsis PI. &Lind. 
B. Corpus lignosum compositum e centrali majore et periphericis minoribus 1 — 4 
a. Folia ternata (sepalum 3 et 5 basi coalita; epidermis quam maxime 
mucigera; sp. mexicana) . . . 7. S. car di o spermoides Schlecht.
