NEW FOEMOSAN PLANTS. 

 By R. a. Rolfe. 



In naming a collection of economic and medicinal plants from 

 the Island of Formosa, sent by Mr. Watters, — many of them, 

 unfortunately, too hnperfect for full determination, — my attention 

 has been drawn to some plants which, as far as I can ascertain, 

 are still undescribed. These it is my purpose to describe in the 

 following paper. 



Ardisia formosana, sp. n. — Branches glabrate. Leaves elHp- 

 tical, obtuse, entire, base attenuate, 2|~3| in. long, l-l|-in. broad, 

 glabrous, coriaceous, without dots ; veins parallel, crowded, running 

 at 60° with midrib ; petiole 4 lin. long. Cymes terminal, many- 

 flowered, scarcely equalling leaves. Bracts subulate, ^ lin. long. 

 Pedicels 2 lin. long. Flowers 2 lin. long. Calyx i lin. long, seg- 

 ments triangular-ovate, ciliate. Corolla tube very short, segments 

 elliptical, obtuse. Filaments very short ; anthers sagittate. Fruit 

 globose, i in. diameter. — Near Tamsui, Oldham, No. 301 ; Watters, 

 No. 42. Bonin Islands, C. Wright, U.S. North Pacific Expedition, 

 No. 188. The Bonin specimen is in fruit, while those from For- 

 mosa are in flower only ; but the leaf, habit, and length of cyme 

 appear identical. Closely allied to A. pedimculosa, Wall. ; it 

 diffars in the shorter and broader leaves ; more compact, shorter 

 cymes ; shorter pedicels and flowers, which in the bud are stouter, 

 and, as well as the petals, less acute. In Formosa the native name 

 is given as Chiu-ki-tsa by Mr. Watters, who says, " The sap is used 

 in making bread." 



Callicarpa formosana, sp. n. — Branches becoming glabrate with 

 age, but when young, as weU as the under side of leaves, the 

 cymes, pedicels, and calyx, covered with a pale brown tomentt!im of 

 stellate hairs. Leaves elliptical, acute or shortly acuminate, 

 serrulate or denticulate, base rounded ; 2-3^ in. long, 1^-- 2-|- in. 

 broad ; dark brown, sparingly pubescent above, slightly scabrid 

 with age ; veins alternate, in about five pairs ;, petiole 3-5 lin.- long, 

 Cymes 5 times branched, dense flowered, 4-5 times longer tha^ 

 petiole. Pedicels h lin. long. Calyx campanulate, scarcely i linj. 

 long, segments minute. Corolla 1 lin. long, lobes rounded, shorter 

 than tube. Stamens exserted 1 lin., anthers elhptical, notched at
