338 THE JOURNAL OF BOTANY 



To be inserted in the genus close to T. Barteri Baill. and 

 T. Tholloni 'Bojill. The distinguishing marks are the large cordate- 

 based glabrous leaves, the broad lobes of the corolla, and the 

 coronal leaves v^ith their short lateral lobes. 



Tacazzea Oleander, sp. nov. Frutex orgyalis a basi ra- 

 mosus, ramis ascendentibus subteretibus longitrorsum striatis 

 puberulis mox glabrescentibus crebro foliosis, foliis oppositis 

 suboppositisve brevipetiolatis lanceolatis apice mucronatis basi 

 rotundatis chartaceis supra glabris subtus tomentellis, cymis 

 pluribus paniculatis quam folia brevioribus, pedunculis pedi- 

 cellisque pubescentibus his floribus longioribus, bracteis parvis 

 subulatis puberulis, calycis pubescentis segmentis deltoideis ob- 

 tuse acutis, corollas altissime partitse lobis calycem certe super- 

 antibus oblongis obtusis glabris, coronse phyllis subulatis acumi- 

 natis apice recurvis quam corollae lobi brevioribus, filamentis 

 quam lobuli intercalati bilobati paullulum longioribus. 



Hab. Angola, banks of Cubango River, near Forte Princeza 

 Amelia ; Gossiueiler, 2310. 



Foliorum limbus plerumque 7-9-5 cm. long., juxta medium 

 15-18 mm. lat., supra dilute olivaceus subtus griseolus ; reticulum 

 satis arctum, pag. inf. optime eminens ; petioli circa 5 mm. long., 

 basi dilatati, pubescentes dorso puberuli. Cymae plereeque 3-5 cm. 

 long., pluriflorae. Flores cernui. Calycis segmenta 1*5 mm. long. 

 Corolla extus rubro -purpurea ; lobi intus luride flavi, 5 mm. long. 

 Coronae phylla 3 mm. long. Filamenta -5 mm. long. ; lobuli inter- 

 jecti -3 mm. long., horum lobi deltoidei, obtusi. Antherae circa 

 1 mm. long. 



From T. venosa Decne. this differs chiefly in the broad-based 

 leaves, the pubescent cymes, the small deltoid segments of the 

 calyx, the narrow petals, and the short coronal leaves. 



Eaphionacme linearis K. Schum. 



Angola, here and there in the marshes of the Kuiriri at Kassu- 

 ango and near Munonque ; Gossiueiler, 2473, 3434. 



Flowers nodding, violet. 



E. GLOBOSA K. Schum. 



Angola, amongst Glumaceae in the fissures of ferruginous rocks 

 in thickets between Forte Princeza Amelia and the River Cubango ; 

 Gossiueiler, 2275. 



This rare species is represented at the British Museum only by 

 a sketch and a couple of flowers from Welwitsch's herbarium. 



Raphionacme virgultorum, sp. nov. Caule nunc e rhizo- 

 mate valido vel tuberoso nunc e caule verisimiliter hornotino 

 radicante erecto spithameo vel paullo ultra striato pubescente 

 superne folioso, foliis vetustioribus oppositis junioribus suboppo- 

 sitis nisi alternis oblanceolatis vel lineari oblanceolatis obtusis 

 basi in petiolum brevissimum angustatis costa media pag. inf. 

 eminente necnon griseo-pubescente exempta puberulis, cymis ter- 

 minalibus subsessilibus vel breviter pedunculatis plurifloris flori- 

 bus satis congestis, pedunculis ut pedicelli et bracte^e et calyces 

 pube grisea dense obsitis, bracteis parvulis filiformibus quam pedi-
