55. Lasianthus saxorum Craib (1933:25) View in CoL . Type: ― THAILAND. Loei, Phu Kradung , 10 February 1931, A. F. G. Kerr 20055 (holotype K000777007!; isotype BK257395!).
Thailand: ―NORTH-EASTERN. Loei: Phu Kradung National Park, 7‒9 November 1970, C. Charoenphol, K. Larsen & E. Warncke 4813 (AAU, BKF, K), 29 December 1971, C. F. van Beusekom et al. 4525 (BKF, K), 16 November 1979, T. Shimizu et al. T23087 ( BKF), 16 November 1979, T. Shimizu et al. T23181 ( BKF), 31 August 1988, H. Takahashi & M. N. Tamura T60558 (BKF, KYO), 31 August 1988, N. Fukuoka T63750 ( BKF).
Distribution: ―Endemic to Thailand (North-Eastern).
Ecology: ―Hill evergreen forest, in shaded places at an elevation of 1000‒1200 m. Flowering in February.
Notes: ― Lasianthus saxorum is close to L. fordii and L. lucidus . It differs from L. fordii by having relatively small leaves that are oblong-elliptic or oblong-lanceolate (not ovate-oblong), 7‒8 × 2‒3 (not 6‒10 × 3‒5) cm, the apex is mostly caudate-acuminate (not acuminate or cuspidate-acuminate), the base is cuneate and slightly oblique (not acute or obtuse), the petioles are usually less than 5 (not 8‒10) mm long, and the drupes are ovoid and narrowed at the base(not globose), 3‒3.5 (not 5‒6 mm) diameter. It differs from L. lucidus by being appressed-pubescent (not glabrous) on mature branches and branchlets, having leaf blades that are coriaceous or subcoriaceous (not mostly membranaceous), the calyx is pubescent (not glabrous or subglabrous) and campanulate (not broad campanulate) with 0.5 (not. 0.2) mm long tube and 0.2 (not 2–3 mm) mm long lobes, the corolla is sparsely appressed-pubescent (not strigose) outside and pilose (not villous) inside, and the drupes are ovoid (not globose) and puberulous (not glabrous). In addition, L. saxorum is similar to L. hispidulus on herbarium specimens but it differ from L. saxorum by having a corolla that is pubescent on the outside and drupes that are subglobose.
