990 MONOGRAPHIA POLYGALACEARUM. 
Subsectio III. 
Capsula margine membranacea, i. e. alata, elliptica vel suborbicularis; stigmata 
hippocampiformia, haud pilosa nec cristata; antheræ haud in tubo staminali ses- 
siles; arillus obsoletus in appendicula duo, membranacea prolongatus. 
Species brasilienses, foliis aut lanceolatis aut sublinearibus, floribus medio- 
cribus, radice erassa, etsi habitu valde dissimiles indolibus internis congruunt. 
Hæc parva subsectio forma stigmatum, capsula alata, subsectioni P. rupestris 
similes; in ea autem arillus deest, loco ejus, appendicula duo sunt descendentia, 
quæ in P. rupestris haud sunt evoluta. 
Species forte huic subsectioni adscribenda. 
P. Darwiniana. 
P. LANCIFOLIA, StHil. 
Caulis sublignosus, erectus, ramosus; folia ovato-lanceolata, submagna, tenuia, 
attenuato-acuminata; racemi terminales sublaxiflori vel densiores ; sepala exteriora 
ovata, ciliata; alæ late obovatæ suborbiculares, eciliatæ vel ciliatæ; carinæ crista 
fimbriata; antheræ quam filamenta libera breviores; stigmata hippocampiformia 
nec cristata; capsula orbicularis marginibus aliformibus cincta, alis persistentibus 
longiora.
