330 SERTULUM CHINENSE TERTIUM: 
longis 1-14 poll. latis petiolo 3-lineali suffultis, racemis axillaribus 
simplieibus vel ramosis pilis ferrugineis glandulosis dense velutinis 
foliis subeequalibus vel dimidio brevioribus, pedicellis velutinis 14-23- 
linealibus, bracteis velutinis ovato-rotundatis caducis, calycis tubo ob- 
conico lobis rotundatis oculo armato minutissime ciliolatis.—In colli 
quodam demisso herbido prope monasterium buddhisticum ad boream 
urbis Shui-tung, in extremitate prov. Cantoniensis australi, d. 15 
Nov. 1866, collegerunt Sampson et Hance. (Exsice. n. 13796.) 
Very closely allied to S. obtusa, Wall, from which it is only to be 
distinguished by the rather less coriaceous leaves, with less prominent 
veins, and by the velvety, frequently compound racemes. In the 
various forms assumed by 8. obtusa in Ceylon, the racemes are, I be- 
lieve, always perfectly smooth. 
ynoctonum insulanum, n. sp. ; ; fasbecaus; vohubile, glaberrimum, 
Kn e basi truncata vel subcordata hastato- vel subtriangulato-lanceo- 
latis vel lanceolatis (lobis nempe basilaribus obsoletis) apiculatis petiolo 
lamina duplo breviore supra pilosulo -suffultis, umbellis 6—12-floris 
pedunculo petiolo equilongo suffultis, calycis laciniis ovatis, petalis 
oblongis obtusiusculis corona staminea tenui alba equaliter 10-fida 
acutiuscula paulo longioribus.—In ins. Hai-nan Martio 1868 collegit 
clar. R. Swinhoe. (Exsicc. n. 14413.) 
This plant resembles in foliage Symphyoglossum hastatum, Turcz., 
but the basal lobes are less developed; the flowers too are twice as 
small I had regarded it as a Cynanchum (with R. Browu's and 
Grenier and Godron's character of which it agrees); the staminal . 
corona, however, is tubular and 10-cleft, with the divisions in a single 
row, so that it does not fall into that genus, as limited by Decaisne. 
It is perhaps near Cynoctonum angustifolium, Dene., but I have no 
critical knowledge of the species.
