NEW EUBIACE^ FROM THE BELGIAN CONaO 309 



of the Belgian Agricultural Department, and one by H. Vanderyst, 

 in the Kwango district. The collection includes over fifty Rvibiaceai, 

 of which these eight are new ; the types are in the National Her- 

 barium, to which the collection was brought by Dr. Vermoesen, 

 Inspector of Agriculture in the Belgian Congo. 



Apart from the actual novelties, the following rare and interesting 

 plants formed part of the collection: — Jiisfenia ortliopetala (Van- 

 deryst 3508 ! 4266 ! 4290 !) hitherto known only from Angola, where 

 it was discovered by Welwitsch, and described by Hiern in Cat. Welw, 

 Afr. PL ii. 452 ; Pouchetia Gilletii de WM. { Fa iideiyst 4317 I) in 

 Ann. Mus. Congo Ser. v. iii. 289 (1910), which is represented at 

 present in British herbaria by a small shoot preserved at Kew ; J^cr- 

 fiera capitata de Wild, from Ituri (leg. Lacomhlez 173 !), hitherto 

 unrepresented in our herbaria, and confined to the Congo. 



The genera are arranged in accordance with their order in. Ben- 

 tham & Hooker's Genera Planfarum. 



Mussenda Nannanii, sp. nov. Frutex volubilis j^artibus in vege- 

 tativis omnino sparse nee tamen obscure potius scabridulius hirtellus, 

 ramulis gracilibus teretibus mox glabrescentibus striatis lenticellosis. 

 Folia pergamacea late elliptica vix acuminata acutissima basi bre- 

 vissime cuneata petiolata ; i'^-^ce principales subtus prominula?, late- 

 rales tenues utrinque 15 v. plures, rete interveniente conspicuo ; stipulce 

 breves crassiusculfe acuminato-deltoideje extus dense rufo-hirtelhe basi 

 breviter vaginantes. Flores albi inter minores (pro genere) umbel- 

 lorum quorumque ± 7-9 flor. in corymbis dispositi dense aurato- 

 sericeis, peduncuHs primariis plus minus elongatis, pedicellis tamen 

 ultimis brevissimis : hractece parvse lanceolate acvitjB plus minus 

 concaveje. Calyx anguste obconicus extus dense aurato-sericeus, 

 lobis minoribus similiter indutis, anguste deltoideis inter breviores, 

 acutis acuminatis, lobo foliaceo minuscvdo obovato venoso basi leniter 

 in petiolo breviusculo jjroducto. Corollce tubus gracilis, extus prse-

 acuminatis acutis extus dense fiavo-strigosis, intus densissime saccha- 

 i-ato-tomentosis. 



Near R. Ikilemba (Equator), Nannan 54 ! 26 August, 1914, 

 dry season. " Plante grimpante le long des arbres. Fleurs blanches. 

 Se rencontre au borde riviere. Sauvage, tres repandue. Nom in- 

 digene : Lofandjar 



Leaves 9-11 cm. X 5-6 cm., -^'x^h petiole 1-1'5 cm. long; stipule 

 5 mm. deep. Main jJ^dinicles about 3 cm. long ; bracts 2-3 mm. 

 long. Ovary (caWx-tube) 2*5 mm., calyx-\ohe?, barely 2 mm. long; 

 foliaceous calyx-lobe 4-5 cm. x 2*5-3 cm., with petiole 1 cm. long. 

 C(oroZ/«-tube 3-3*5 cm. long, limb barely 8 mm. in diameter. 



Of this species M. Chippii Wcrnhara (in Journ. Bot. 1913, 237) 

 is the nearest ally ; it is readily distinguished by the venation of the 

 leaves, the indumentum of the corolla, and the narrower corolla- 

 limb.

 culis dense pra^sertim in juventute patente hispidulo-pllosis. Folia
