112 D. Prain — Some additional species of Convolvulacese. [No. 2, 



Borneo and the Philippines. The form collected by Father Scortechini in Larut 

 differs somewhat from both the Indian and the Java plant ; it has the widely 

 urceolate corolla of L.flavescens, and therefore is not true L. Wallichii; at the 

 game time it has sepals that are longer and more lanceolate than even in L, 

 Wallichii, and therefore is not true L.flavescens. 



Dr. Stapf writes : — " I do not think that L. flavescens, L. Wallichii, and the 

 Borneo-Philippine plant are specifically distinct. They seem to be very slight 

 variations of one species." This opinion, coupled with the communication from an 

 intermediate locality of a form that combines the characters of Steudel's two 

 *' species," leads the writer to propose the identification of the Indian plant with 

 that distributed throughout the Malayan region, 



9. CONVOLVULUS Linn. 



* Erect or diffuse, not tivining {except sometimes C. glomeratus); 

 stigmas filiform, nearly as long as, or longer than the style. 



t Spiny or spinescent shrubs or under-shrnbs. 



1. * Convolvulus LEiocALTCJNcrs 5om. jPZor. Orient, iv., 86; a rigid 

 shrub witli elongated again dividing branches, young parts adpressed- 

 silky, elsewhere glabrous, the ends of branches and peduncles develop- 

 ing into short sharp spines, leaves small shortly petioled, shortly silky 

 hairy, spathulate oblong subacute with rounded or sub-hastate bases, 

 flowers solitai-y axillary, pedicels shorter than the leaves, sepals glabrous 

 coriaceous ovate-obtuse mucronulate, corolla white glabrous 5-6 times 

 longer than the calyx, ovary hirsute, stigmas filiform, as long as the 

 style. C. lasiophlaeus Jaiib. ^' Spach, III., t. 368. C. lycioides Boiss.

Panjab Frontier: BuTce ! British Beluchistan: Lace! Distrib, 

 Afghanistan {Bellew) \ Beluchistan, Persia. 



Height 3-4 feet; leaves J in. or less; calyx ^ in.; corolla 1-li in. long, capsule 

 ovoid. 



The occurrence of this species just within the British Indian frontier renders 

 it necessary to supply a description of the plant. It is readily distinguished from 

 the next species by its hastate or cordate-based leaves. 



1. * * Convolvulus spinosus Burm. Flor. Lid. 47, t. 19, f. 4; 

 a low much-branched shrub with elongated again much divided branches, 

 all parts covered with a short adpressed ash-grey silky pubescence, 

 the ends of branches developing into sharp slender spines ; leaves 

 small elliptic subacute, bases nai'rowed, the uppermost linear and 

 scale-like ; flowers on axillary, 1-3-fld. pedicels as long as the leaves, 

 sepals hirsute coriaceous ovate-obtuse, corolla hirsute 3-4 times longer 

 than the calyx, ovary hirsute ; stigmas filiform as long as the style.
