NEW AFRICAN PLANTS 187 



ovato-lanceolatis acutis trinervibus fere omnino glabris, calycis 

 dentibus deltoideis obtusissimis glabris, corollae tubo ex bracteolis 

 eminente paullulum supra basin contracto inde gradatim dilatato 

 lobis rotundatis abbreviatis, antherarum loculis basi barbatis loc. 

 altero valide incurvo-calcarato, stigmatis ore triangulari angulis 

 barbatis. 



Hab. N.W. Ehodesia, Broken Hill ; Rogers, 8642. 



Folia magnitudine valde diversa, inferiora circa 35 x 4 mm., 

 superiora adusque 8 vel etiam 9 cm. long, et 5-7 mm. lat., omnia 

 in sicco griseolo-viridia et longitrorsum rugulata. Pedunculi 

 23-30 mm. long. Bracteolae circa 22 x 8 mm. Calyx 1-75 mm. 

 alt. ; hujus dentes lxl mm. Corollae tubus 27 mm. long., juxta 

 medium 8 mm. faucibus 10 mm. lat. ; lobi circa 5 mm. long. 

 Antherarum connectivus apice breviter productus, loculi (incluso 

 calcare) 3 mm. long. Stigma 4 mm. diam. 



To be inserted in the genus next T. stellarioides Burkill, from 

 which its different foliage and larger and broader bracteoles afford 

 easy means for separation. 



Thunbergia (§ Thunbergiopsis) glaucina, sp. nov. Erecta, 

 humilis, caule plerumque ramoso glabro, foliis sessilibus anguste 

 linearibus acutis primo minute puberulis mox glabris et (ut caulis 

 bracteolaeque) aliquanto glaucis, floribus in axillis solitariis vel 

 binis pedunculis folia interdum excedentibus fultis, bracteolis inter 

 se liberis ovatis apicem versus attenuatis apice obtusis glabris a 

 basi 5-nervibus nervis haud conspicuis aliquanto perlucidis et 

 reticulum arctum ostendentibus, calycis dentibus abbreviatis del- 

 toideis, corollae tubo bracteolas leviter excedente paullulum supra 

 basin constricto inde gradatim amplificato lobis obovatis tubo 

 brevioribus, antherarum loculo altero basi obtuso barbatoque 

 altero incurvo-calcarato aut barbato aut (verisimiliter rarius) 

 calvo, stigmate late infundibulari ore triangulari ad angulos 

 barbato. 



Hab. South Congo, Elisabethville ; Rogers, 10,320. 



Planta 8-12 cm. alt. Folia infima parvula, 5-7 mm. long., 

 superiora 2-3-5 cm. long., 2 mm. lat. vel etiam minus. Pedunculi 

 compressi, glabri, plerique 1*5-3 cm. long. Bracteolae 2-2-2-5 cm. 

 long., summum 1 cm. lat. Calyx 1-25 mm. alt. ; dentes -5 mm. 

 Corollae tubus fere 3 cm. long., ima basi 6*5 mm. paullulum supra 

 basin 4 mm. lat., faucibus 13 mm. ; lobi circa 12 mm. long. 

 Filamenta compressa, 9-11 mm. long. ; antherarum connectivus 

 ultra loculos usque ad 1 mm. productus ; loculi alteri 2*5 mm. 

 alteri 3 mm. long. Stylus 13 mm. long, ; stigma 7 mm. long., 

 ore 6 mm. lat. 



Under the same number Mr. Eogers sends other specimens 

 with linear-oblong leaves 4-7 mm. broad, but otherwise agreeing 

 with those just described. Thus may be distinguished as var. 



LATIFOLIA. 



The plant, which is allied to T. stellarioides Burkill, does not 

 seem conspecific with any one of several recently described species 

 having the same affinity. From T. stellarioides it is at once known 

 by the leaves and the bracteoles.
