3. B. pseudocroceum Wolff nov. spec. — Planta habitu fere speciei praecedentis. 

 Folia inferiora non visa, superiora firma, viridia, impellucida, suborbicularia vel late 

 ovato-orbicularia , obverse campanulata, margine — in sicco — undulata, 25 — 45- 

 nervia, usque 5 cm longa, usque 3 cm lata, ad apicem caulis ramorumque decrescentia. 

 Umbellae longe pedunculatae, 4 — 5 cm latae, 8 — 1 2-radiatae, radiis subfiliformibus, sub 

 anthesi usque 1,5 cm longis. Involucelli phylla flavido-viridia, semipellucida, plane libera, 

 vel breviter connata, ovata vel obovata, basin versus sensim angustata, abrupte brevissime 

 acuminata, submucronulata, 5-nervia, 5 — 7 mm longa, 3 — 4 mm lata, umbellulas 7 — 8 mm 

 latas duplo superantia. FJores parvi, ad 1 5 in unaquaque umbellula, pedicellis inaequa- 

 libus 2 — 3-plo breviores ; petala obtrapezoideo-rotundata, lobulo inflexo 2 — 3-plo breviore, 

 apice obsolete tridenticulato instructa. Ovarium sub anthesi plane laeve. — Fig. 5 .ff.

Nota 1. Cujus speciei sine dubio novae tantum pars superior mihi suppetebat; fructus 

 maturos non vidi, quam ob rem species forsan serius, fructibus maturis notis, in subsectionem 

 proximam collocanda erit. 



Nota 2. B. Wittmani a cl. Steven in Verz. taur. Pfl. descriptum sec. cl. autorem a 

 B. rotundifolio umbellis 6 — 10-radiatis differt. Plantam Stevenianum non vidi; e descriptione sola 

 non satis elucet an B. Wittmani ad B. rotundifolium vel ad nostram speciem pertineat. 

 Itaque nomen mihi plane incertum remansit atque nomen novum constitui.

 Glaucescens vel glauco-viride, usque 50 cm altum, habitu fere specierum praeceden- 

 tium, sed caule plerumque crassiore, magis et haud raro subcorymboso-ramoso, ramis 

 erectioribus, =b abbreviatis. Folia inferiora breviter petiolata vel subsessilia, oblongo- 

 ovata vel -lanceolata, apice obtusa; folia cetera plane perfoliata, media superiora- 

 que late ovata vel suborbicularia, apice obtusissima, usque 25-nervia, 3 — 5 cm longa, 

 2 — 3 cm lata, summa rameaque sensim minora, suborbicularia, ca. 15 — 21-nervia. 

 Umbellae breviter pedunculatae, 8 — 1 2-radiatae, radiis confertis, inaequalibus, crassius- 

 culis, sulcatis, 0,5 — 1 cm longis. Involucelli phylla 5 — 6, patentia, pallide viridia 

 vel viridi-flavescentia, valde inaequalia, exteriora ovata vel obovata vel obovato-lanceo- 

 lata, rarius elliptico-oblonga, apice subsubito breviterque acuminata, 5 — 7-nervia, nervis 

 prominentibus manifeste denseque subpinnato-venosis, interioribus 3-nerviis multo majora, 

 umbellulas 8 — 15-floras duplo vel rarius usque subtriplo superantia. Pedicelli sub an- 

 thesi tenues, demum incrassati, flores aequantes, fructibus paulo breviores. Petala 

 subsemiorbicularia vel obtrapezoidea, nervo laxe pinnato-venoso percursa, lobulo inflexo 

 rectangulo quam petalum dimidio breviore instructa. Fructus brunneus, elliptico-oblongus, 

 apicem versus attenuatus, subsulcatus, stylopodio vix horizontaliter prominente coronalus, 

 ca. 3 mm longus, ca. 1 y 4 mm latus; mericarpia jugis subfiliformibus instructa, trans- 

 verse secta pentagona, ad commissuram latam plana; pericarpium satis crassum; vittae 

 subobliteratae; endospermium ad faciem leviter excavatum. — Fig. 5 A — D.
