LINOCIERA VERRUCULOSA sp. nov. 



Arbor circiter 10 m alta, ramulis et inflorescentiis plus minusve 

 subferrugineo-pubescens ; foliis subcoriaceis, oblongis, usque ad 

 24 cm longis, breviter et abrupte subapiculato-acuminatis, basi 

 acutis, in siccitate brunneis, nitidis, laevis, eglandulosis ; nervis 

 lateralibus utrinque 10 ad 12, supra impressis, subtus prominulis, 

 anastomosantibus, reticulis laxissimis; paniculis lateralibus, 6 

 ad 8 cm longis, pubescentibus, bi- vel tripinnatis, floribus in 

 ramulis subspicatim dispositis, 4-meris, calycis ovoideis, 1.2 mm 

 longis; fructibus ellipsoideis, in siccitate atro-brunneis, junioribus 

 circiter 1.3 cm longis, perspicue verrucosis. 



A tree about 10 m high, the branchlets and inflorescences more 

 or less ferruginous- or subferruginous-pubescent. Branches 

 grayish, smooth, terete, the branchlets pale-brownish. Leaves 

 oblong, subcoriaceous, 20 to 24 cm long, 7 to 8 cm wide, brown 

 and shining when dry, somewhat paler on the lower surface than 

 the upper, smooth, eglandular, the base acute, the apex abruptly 

 and broadly subapiculate, the midrib and nerves impressed on 

 the upper surface, prominent on the lower surface, the nerves 

 10 to 12 on each side of the midrib, prominent, anastomosing, 

 the reticulations very lax; petioles 1 to 1.2 cm long. Panicles 

 lateral, 6 to 8 cm long, peduncled or branched from near the 

 base, bi- or tripinnate, the flowers subspicately crowded on the 

 ultimate branchlets, 4-merous, subsessile or very shortly pedi- 

 celled, the bracts pubescent, 1.5 mm long or less. Calyx ovoid, 

 about 1.2 mm long, the lobes ovate, obtuse, pubescent, 0.8 mm 

 long. Corolla not seen. Fruits (immature) when dry blackish- 

 brown, ellipsoid, about 1.3 cm long, very prominently verrucose, 

 their pedicels about 2 mm long, much thicker than long. 



British North Borneo, in forests along the Kalabakan River, Villamil 

 22A, September 26, 1916, altitude about 3 meters. 



This species is strikingly characterized by its prominently verrucose 

 fruits, all other species of the genus known to me having smooth fruits. 

 In vegetative characters it closely resembles Linociera callophylla (Blume) 

 Knobl., as I have interpreted the latter from the short and imperfect 

 description, and is also similar to "IV, A, 120" in cultivation in the Botanic 

 Garden at Buitenzorg, Java, from Sumatra; the latter bears an unpub- 

 lished name of Scheffer's, and Boldingh 5 has erroneously referred it to 

 Chionanthus ramiflora Roxb., with which it has little in common. It is 

 suspected that this specimen will prove to be the same as Linociera callo- 

 phylla Knobl.
