BALSAMINACEJS. 



79. Impatiens prothacta Hook. fil. 



Dran, 3,000-4,000 ft. A herb with opposite leaves and with 

 purplish red flowers in the axils of the leaves. 



Lian Khanh Falls, 3,000ft. "Flowers bluish red." Dalat. 

 In wet grass land. " Flowers maroon red." 



The above differ in size and colour of flowers but do not seem 

 specifically separable. 



Distrib. Annam. 



AMPELIDACEM 

 80. Tetrastigma plaxicaule Gagnep., var. annamensis Bak. 



fil., var. nov. 



Cirrhoswm scandens. Caulis glaber. Folia saepissime 4 

 foliolata, foliolis elliptico-lanceolatjs margine serratis supra glabris 

 penninerviis apice subacuminatis 9-13 cm. longis, 3-4-5 cm. latis 

 longiuscule petiolulatis pstiolulis 2-4 cm. longis, petiolo communi 

 7-10 cm. longo suffulta. Inflorescentia composita, multiflora, laxa, 

 corymbosa. Flores fceminei. Galyx brevis, papillosus. Petala + 4 mm. 

 longa, extus sublenta minute papillosa, lanceolata. Ovarium conicum, 

 stylo brevissimo, stigmate dilatato 4-lobato. Fructus ignotus. 



Langbian Peaks, 6,000 ft. A scandent shrub with usually 

 4-foliolate leaves and a lax corymbose cyme. 



I have carefully compared this with the figure of Vitis plani- 

 caulis Hook, fil., Bot. Mag., t. 5685. The plant from Annam differs 

 more particularly in having a much laxer broader inflorescence, and 

 the leaves are only 4-foliolate. 



81. Leea coccinea Planch. 



Dran, 3,000-4,000 ft. " Stem, buds, edges and base of leaves 

 red."
