NOTES ON AFRICAN CONVOLVULACE^ 13 



apice obtusiusculis, facie superiore atrato-viride, glabra cum punc- 

 tulis pellucidis notata, facie inferiore sparse pilosa cum nervo 

 mediaiio venisque pinnatis valde asceudentibus prominentibus, 

 breviter petiolatis ; floribus solitariis vel geminis, pedunculis obsol- 

 etis, bracteolis lineari-lanceolatis acutis pilosis, pedicellis quam folia 

 brevioribus, pubescentibus ; sepalis e basi lanceolata lineari-acumi- 

 natis, ^qualibus, dorso marginibusque breviter pilosis ; corolla 

 marcida, ut apparet tubuloso-campauulata et calycem baud super- 

 ante, luteola (?), areis mesopetalis nervis binis conspicuis definitis ; 

 staminibus subsequalibus, tubo inclusis, antlieris elliptico-sagittatis ; 

 stigmate subgloboso ; capsula pilosa biloculare, cum valvis 4 dehis- 

 ceute ; seminibus 4, breviter et appresse cinereo-pilosis. 



Described from a shoot broken below the apex, 60 cm. long, not 

 exceeding 2 mm. in diameter. Leaves reaching 4 cm. long by barely 

 1-5 cm. broad at the hastate base. Bracteoles 6-8 mm. long by 

 1-1-5 mm. broad ; flowering pedicels 6-12 mm. long, increasing in 

 the fruit to 1-7 to 2 cm. Sepals 1 cm. long, 2-2-5 mm. broad, in- 

 creasing in the fruit to 1-5 cm. in length and 3 mm. broad in the 

 lower part, the linear acuminate apex becoming incurved. Corolla 

 apparently about equal to the calyx in length, with a tube 2 mm. in 

 diameter. Filaments 2-5-3 mm. long, anthers a little over 1 mm. ; 

 style 3-5 mm. long. Fruit globose, 7-8 mm. in diameter ; seeds 

 4-4-5 mm. long, 1*75-2 mm. broad. 



A very distinct species of the section, perhaps nearest to I. his- 

 pida E. & Sch., which it resembles in habit, but is distinguished by 

 its hastate leaves, with triangular not cordate base, solitary or 

 geminate stalked flowers, and long attenuated sepals. 



Hab. South Africa, Zeijher, 1846, no. 1224. 



I. Hindeana sp. nov. Suffrutex humilis ramo abbreviato (in 

 specimine singulo) sparse hirsutulo ; foliis oblongo-hastatis, obtusis, 

 basi subcordata, lobis rotundatis, facie superiore glabra hispidula, 

 atrate viride, facie inferiore in venis venulisque sparse hirsutula, 

 margine breviter hirsutulo, petiolis tenuibus, aequilongis vel quam 

 lamina paullo brevioribus, hirsutulis; pedunculis tenuibus petiolos 

 sequantibus vel excedentibus, glabrescentibus, floribus 2 mono- 

 chasialibus ; bracteolis lanceolatis acutis, pedicello glabro subfili- 

 forme pedunculum sub^quante ; sepalis lanceolatis acutis, dorso 

 sparse hirsutulis ; corolla infundibuliforme calycem 2^-plo ex- 

 cedente, albo (?), areis mesopetalis distinctis, sparsissime pilosulis, 

 cum venis binis luridis conspicue limitatis. 



The specimen consists of a slender branch, 1 cm. long, spring- 

 ing from a short stouter woody shoot, 1-5 mm. in diameter, and 

 bearing a few crowded leaves at the apex, in the axil of each of 

 which springs an inflorescence. Leaves to 2 cm. long by 1 cm. 

 broad at the base ; basal lobes spreading, barely 3 mm. broad ; 

 petioles 1-5-2 cm. long. Peduncle 2-3 cm. long, bracteoles -5 cm. 

 long, pedicel of opened flower (terminal) equal to the peduncle 

 (2 cm.). Sepals 1 cm. long by 2 mm. broad at the base. Corolla 

 2-5 cm. long, about 2 cm. broad at the mouth. 



A very distinct species, the flowers resembling those of /. mom- 

 bassana Hall, f., but the sepals show no trace of the basal auricles
