11. Ipomcea.] 96. GONVOLVULACEM. 



{I. purpurea), an annual tropical American species usually called Convolvulus 

 major by horticulturalists, and the beautiful blue perennial I. Learii, etc. 



1. I. uniflora, Boem. Syn. Aniseia uniflora, Chois. 



A creeping and twining herb Avith glabrescent stems, oblong, 

 obtuse or emarginate, mncronate leaves I'S-SS" long mostly with 

 slender •3--5*' long petioles and solitary campantilate white flowers 

 •8-1" long. Sepals in flower •4-"5", fruiting reticulate-venous, •6-"75" 

 and somewhat decurrent on the pedicel, two outer ovate subcordate 

 scarious. Corolla rather densely hairy. Capsule ovoid glabrous "S". 



Usually found near jheels! Chota Nag-pur, Beng. Plants; but I can find no 

 specimens from Chota Nagpur either at Calcutta or Kew. 



Leaves with usually cuneate base. Peduncle with pedicel l'5-2" long with a pair 

 of minute persistent bracts. Corolla-lobes short acute. 



The i)ollen of this species is quite smooth, for which reason it has been placed in 

 a separate genus Aniseia by many botanists. It appears to me to be too close ta 

 the two next to thus separate it. 



2. I. barlerioides, Benth. 



A trailing herb or ultimately twdning with hirsute or hairy stems> 

 ovate-oblong leaves 1-2" (-3" Clarke) long Avith shalloAA'ly cordate 

 base and rounded, rarely acute, often mucronate apex. FloAvers 

 light-purple about 17" long and 1"25-15" diam. on axillary bracteate 

 1- (rarely 2-) fld. peduncles. Calyx hairy A\dth 2 outer large leafy 

 OA-ate -lanceolate or lanceolate sepals 'SS-'T" long and 3 inner much 

 narroAA'er linear sepals, but nearly as long in floAver. 



Usually in grass. Rauchi and Palamau, on the tops of the pats ! Manbhum, 

 Camp. ! Hazaribagh, Clarke I Fl. May-Oct. 



Branches annual from a Avoody stock. Leaves hairy especially on the nerves 

 beneath, sec. n. 3-5, of Avhich 1-3 from the base each side. Petiole ■15-*25" long. 

 Peduncles at first A'ery short and about as long as petiole, soon elongating and 

 sometimes attaining 3" in fruit, hairy, Avith tAvo hairy lanceolate or ovate-lanceolate- 

 bracts towards the end S-'o" long. Pedicel very short. Corolla funnel-shaped 

 from a basal very narrow tubular portion, bands Avell-marked Avhen fresh, about 

 5-7-nerved. Fruiting sepals nearly I" long. Capsule "S" ovoid, glabrous. " Seeds 

 oblong, villous or pubescent" (Clarke). 



3. I. calycina, Benth. 



Slender, tAvining, haiiy or villous Avith ovate and usvially deeply 

 cordate, rarely oblong or shalloAvly cordate, leaves 1-3" long,

4. I. hispida, -Roem. Syn. I. eriocarpa, iJ. £r. ; Convolvulus hispidus,
