2o8 Convolvulacece. \_Argyreia 



pubescent, scarcely enlarged in fruit ; cor.-tube over i in, 

 long-, limb about i^ in. diam., hairy on plaits outside ; fil. 

 hairy at base ; fruit globose, somewhat depressed, smooth, 

 fleshy, yellow. 



Var. /3, coacta, Clarke in Fl. B. Ind. iv. 189 (sub A. hirsuta). Rivea 

 zeylanica, var. /3, hirsuta, Thvv, Enum. 209. C. P. 1944. 



Stems more hairy, 1. silky-hairy on both sides, bracts 

 longer and narrower. 



Low country and hills up to 5000 ft., very common, var. /3 somewhat 

 less so. Y\. May, June ; pale violet-pink, shading into red-purple in the 

 tube. 



Endemic. 



One of the most abundant plants everywhere within its range, and not 

 variable. The flowers are occasionally white. Has a bitter milky juice. 



Var. /3 should perhaps be considered a distinct species. It is near 

 Rivca hirsuta, Wight, Ic. t. 891, to which Thwaites and Clarke refer it.* 

 The Fl. B. Ind. has a var. Thivaitesii with narrower leaves and bracts. 



4. A. pomacea, Chois. in DC. Prod. ix. 329 (1845), var. triflora, 

 Clarke in Fl. B. Ind. iv. 188. 



A. Leschenaultii, Thw. Enum. 210 (non Chois.). C. P. 1932. 

 Fl. B. Ind. iv. 188. 



Stems long, woody below, slightly rough with adpressed 

 hair ; 1. 2-3 in., ovate or ovate-lanceolate, more or less rounded 

 at base, acute, nearly glabrous above, more or less strongly 

 hairy beneath, i:)ctiole shorter than 1.; fl. on very short ped., 

 3 or more in cyme, peduncle 1-3 in., bracts numerous, oblong, 

 obtuse or apiculate, hairy, persistent ; sep. ovate, obtuse, 

 slightly hairy, not much enlarged in fruit ; cor.-tube about 

 I in., very hairy outside, limb about f in. diam.; fruit de- 

 pressed-globose, I in., smooth, yellow. 



Dry region, rare. Batticaloa (Gardner); Trincomalie. Fl. August ; pink. 



The type in S. India, our variety endemic. 



I do not well know this plant, which seems to be maritime with us, 

 and may possibly be a coast variety of A. popitlifolia. The typical A. 

 poniacca is figured in Wight, Ic. t. 888, and is a very hairy plant. 



5. A. Choisyana, Wight, ex Fl. B. Ind. iv. 190 (1883). 

 Batatas Choisyana, Wight, Thw. Enum. 210. C. P. 3647. 



Fl. B. Ind. iv. 190 (not given for Ceylon). Wight, Ic. t. 491 {Batatas). 



Stem hairy with spreading hair ; 1. small, very hairy on 

 both sides, oval-oblong, apiculate ; bracts linear-lanceolate, 

 acute, hairy ; sep. linear, hairy ; cor.-tube about i in., glabrous ; 

 fruit not seen. 



Dry region ; verj' rare. I have seen only the single poor specimen 

 with two leaves and one flower, which represents C. P. 3647. It is 

 labelled, 'Batticaloa, March, 1858.' 



Also near Madras, S. India. 



* The figure oi A. hirsuta in Bot. Mag. t. 4940 has much larger flowers.
