IXORA Linn. 



Ixora chartacea Elm. n. sp. 



A slender tree-like shrub; stem terete, 5 cm. thick, 

 crooked, 3 m. high, few branched toward the top; wood 

 dingy or yellowish white, moderately hard, odorless and 

 tasteless, covered with smooth and brown bark; main branches 

 relatively short, divaricately spreading, few branched and rigid, 

 glabrous even the subterete apical portion. Leaves opposite, 

 scattered, rigidly chartaceous, descending, the entire sides 

 coarsely wavy and the sharply acute to acuminate apex twist- 

 ingly recurved, glabrous, dull gray or grayish brown on both 

 sides, much lighter or yellowish green beneath, the average 

 blades 2 dm. long by 4 cm. wide across the middle, the 

 larger ones considerably wider, oblong or the smallest ones 

 linearly lanceolate and usually situated at the basal portion 

 of the branchlets, base bluntly obtuse or subcuneate, lucid 

 above even so in the dry state, edges somewhat recurved; 

 midrib raised beneath and ater when dry, shallowly canicu- 

 late along the upper side; lateral nerves 8 to 11 on each 

 side, much lighter in color when dry and much less con- 

 spicuous, ascending, strict, branched toward the distal end 

 and very coarsely anastomosing, frequently with intervening sec- 

 ondary ones, reticulations coarse and equally plain on both 

 sides; petiole 1.5 to 2 cm. long, much thickened for the 

 basal two thirds and ascendingly curved, subterete: stipule 

 also subchartaceous, 5 mm. long, quite broad and sharply 

 pointed, the basal portion more or less persistent. Inflores- 

 cence terminal or lateral and generally solitary; peduncle 

 slender, pendant, 1 to 2 dm. long, flexible, glabrous, deep red 

 in the fresh state, obscurely expanded at the distal branch- 

 let bearing end, at the base subtended by stipular bracts and 

 generally by a pair of ovate to oblongish foliaceous bracts; 

 branches corymbosely paniculate, forming a 5 cm. wide inflores- 

 cence; rebranched from below the middle, angularly flattenel
