TRIBE 1. PERIPLOCEJE. 

 1. FENTANURA, Blume. 



Twining glabrous shrubs. Leaves opposite, elliptic, strongly nerved. 

 Floivers small, fascicled on a short axillary peduncle, purplish. Calyx small, 

 5-glandular within. Corolla subcampanulate, fleshy ; lobes concave, over- 

 lapping to the right. Coronal scales 0. Filaments free, arched, bases distant ; 

 anthers oblong, adherent below to the stigma, tipped with bearded appendages ; 

 pollen-masses granular ; appendages of the corpuscles stipitate, flabellate. Stigma 

 capitate, 5-angled. Follicles divaricate, cylindric. Seeds comose.' Species 2; 

 a Sumatran and the following. 



P. khasiana, Kurz in Herb. Calcutt. j glabrous, leaves elliptic-lanceo- 

 late acuminate at both ends, petiole slender. Pentanura sp., in regione Yunan 

 and Periploca khasiana, Benth. in Gen. PL ii. 740 and 746. 



KHASIA MTS., alt. 3-4000 ft., J. D. H. $ T. T., Kurz. DISTRIB. Yunan. 



Branches smooth. Leaves 4-5 by 1-1^ in., reddish when dry beneath and finely 

 reticulated, midrib stout; nerves 8-10 pairs, arched ; petiole ^-f in. Peduncle stout, 

 J- in. in the Khasian specimen, -1 in. in the Yunan ones. Corolla about in. diam. ; 

 lobes pubescent within, pink. Filaments and back of anther pubescent as in Phyttan- 

 thera (which is perhaps not generically distinct) in the Yunan specimens, glabrous in 

 the Khasian. Style elongate ; stigma 2 -lobed at the top. Follicles (young) in 

 Khasian specimen ^-f in. long, ovoid, incurved, obtuse. I have not seen the 

 Sumatran species which is the type of the genus. 



2. HEIKIDESIKUS, Br. 



Twining shrubs. Leaves opposite, hoary or pubescent beneath. Flowers 

 small, in opposite crowded subsessile cymes, greenish -purple. Sepals glandular 

 within, acuminate. Corolla rotate ; lobes thick, valvate. Coronal scales 5, on 

 the corolla- throat, alternate with its lobes, short, thick. Filaments distinct ; 

 anther-tips connate, inflexed, membranous; pollen-masses cohering in pairs in
