ASCLEPIADACE^ AFRICANS 367 



prope apicem ramorum foliis orborum geniti. Pedicelli 3-5-4 cm. 

 long. Calycis segmenta 1 mm. long. Corollae atropurpm^eae 

 tubus 1 mm. long. ; lobi 1*25 mm. long., basi -8 mm. lat. Coronas 

 phylla ext. 1 mm. long., horum lobi 45 mm. ; phylla int. -5 mm. 

 long. Pollinia -2 mm. long. 



Easily recognized by the slender habit and the fascicles of 

 small flowers on long nodding pedicels. 



The genus has comprised hitherto seven species, of which two 

 are natives of Somaliland, one of German East Africa, and four of 

 South Africa, ranging from Eastern Cape Colony to the Transvaal. 

 A considerable extension of the area occupied by the genus is 

 shown by the occurrence in Angola of the species under notice. 



Caralluma Gossweileri, sp. nov. Planta crebro ramosa 

 ramis patulis prostratis radicantibus 4-angulatis anguHs lobis 

 magnis triangularibus prseditis, floribus circa 7-nis in umbellis 

 sessilibus approximatis lateralibus apicalibusve dispositis, bracteis 

 lanceolatis acuminatis quam pedicelli crassiusculi multo breviori- 

 bus, calycis segmentis ovato-lanceolatis acuminatis patentibus, 

 corollae alte partitae tubo subhemisphaerico lobis elongatis anguste 

 lineari-lanceolatis acutiusculis vivis extus nitidis intus rugosis, 

 coronae phyllis exterioribus ad 1 mm. supra basin ex columna 

 staminea oriundis basi coronae piiyllis int. adnatis scutiformibus 

 margine superiori dentatis phyllis interioribus stamina longe ex- 

 cedentibus linearibus obtusis inferne subhorizontalibus superne 

 recurvis basi dorso prominenter gibbosis. 



Hab. Angola, Kubango, in thickets on ferruginous rocky 

 ground near Forte Princeza Amelia ; Gossiveiler, 2098. 



Eadices satis numerosae, crassiusculae, sub apice solummodo 

 ramosae nisi simplices, circa 4-5 mm. long. Caulis in sicco circiter 

 10 mm. diam., hujus lobi 13 mm. alt. Bracteae 3 mm. long. ; 

 pedicelli + 15 mm. long. Calycis segmenta 5*5 mm. long., basi 

 3*5 mm. lat. Corolla theobromina intus fusca ; tubus intus 

 rugosus, 7 mm. long., 8 mm. lat. ; lobi 4*5 cm. long., juxta basin 

 5 mm., medio 3 mm. lat., indeque gradatim angustati. Coronae 

 ext. phylla 2-5 mm. long., 1-5 mm. lat. ; coronae int. 3-5 mm. long. 

 Columna staminea 2*5 mm. long. Antherae -75 mm. long. Pollinia 

 subquadrata, -65 mm. long. 



This has much the appearance of C. lutea N. E. Br., a yellow- 

 flowered species from the Transvaal with shorter ciHate corolla- 

 lobes, broader outer coronal leaves and inner coronal leaves with 

 two teeth one behind the other. 



MABSUPELLA APICULATA SchiffxN. IN BRITAIN. 



By W. E. Nicholson. 



Two of the species mentioned by Mr. Macvicar in his excellent 

 Student's Handbook of British Hepatics as likely to occur in 

 Britain have already been recorded as British on p. 287, and I am 

 glad to be able to add a third in the shape of Marsupella apicnlata
