Here may be added the description of three new species collected by A. Henry 

 in Yunnan. 



Symplocos tetramera Rehder, n. sp. 



Arbor 12-14-metralis glaberrima; ramuli angulati, glabri, flavido-cinerei. Foha 

 coriacea, persistentia, elliptica, breviter et obtusiuscule acuminata, basi late 

 cuneata, minute et obscure denticulata denticulis fere ad glandulam adustam 

 reductis, 5-7.5 cm. longa et 2.5-3.5 cm. lata, glaberrima, supra luteoviridia, subtus 

 pallidiore, costa media supra manifeste impressa, nervis utrinsecus 6-7 supra 

 leviter v. vix impressis subtus leviter elevatis. Flores in fasciculis axillaribus 10- 

 20-floris, polygamo-dioeci ? (masculi tantum visi); pedicelli graciles 1-4 mm. longi; 

 calyx cupularis, 4-lobus, lobis semiorbicularibus minute ciliolati, ceterum glabri, 

 corolla tubo brevissimo, lobis 4 oblongis obtusis patentibus vix 3 mm. longis; 

 stamina 4, petala subaequantia; rudimentum pistilli subglobosum, sepala paullo 

 superans, basi tantum tubo calycis adnatum. Fructus desideratur. 



Yunnan: Puerh Fu, alt. 1600 m., A. Henry (No. 13273). 



This remarkable species is not closely related to any Asiatic species, but seems 

 nearest to the South American S. tetrandra Martins and S. variabilis Martius which 

 both belong to the section Barberina of the subgenus Epigenia, characterized by 

 polygamous flowers and 4-25 free stamens. The individual flowers look very much 

 like those oi S. tetrandra as figured in the Flora Brasiliensis (VII. t. 14, fig. 1) except 

 that the style is wanting, while the shape of the calyx and of the rudimentary ovary 

 resembles closely that of S. variabilis figured in the same work (VII. t. 11, fig. 3 

 and 4) except that there are only 4 stamens in our plant. In fohage our species 

 resembles the Chinese S. decora Hance so closely that without flowers it might be 

 taken for it. The occurrence in Asia of a species belonging to the subgenus Epigenia 

 known before only from South America and the West Indies forms a parallel case 

 to S. tinctoria L'Heritier which is the only American species of the otherwise purely 

 Asiatic subgenus Hopea. 



Symplocos pilosa Rehder n. sp. 



Arbor 3-metralis; ramuli hornotini dense flavido-pilosi, secundo anno tarde 

 glabrescentes, vetustiores glabri fusco-purpurei. Folia papyracea, partim sub- 

 persistentia, oblonga v. oblongo-lanceolata, basi rotundata, satis longe acuminata, 

 serrulata, 7-15 cm. longa et 2.5-4.5 cm. lata, supra laete viridia, glabra, subtus 

 ad nervos venulasque pilosa, nervis utrinsecus 7-10, supra ut costa media impressis, 

 subtus elevatis; petioli dense pilosi, circiter 5 mm. longi. Racemi axillares prae- 

 cipue in basi ramulorum numerosi, plerumque basi ramosi, interdum simplices, 

 2.5-4 cm. longi, rhachide, pedicelhs, bracteis, tubo calycis dense flavido-pilosis; 

 pedicelli 1-2 mm. longi, rarius inferiores longiores; bracteae lanceolatae, circiter 4 

 mm. longae, intus glabrae; bracteolae lineari-lanceolatae, 2-2.5 mm. longi, circiter 

 dimidios lobos calycis attingentes; calycis lobi ovati, obtusi, 2 mm. longi, tubum 

 paullo superantes, longe ciliati, intus glabri, extus sparse pilosi, patentes; corolla 

 fere ad basin partita, lobis ovali-oblongis, obtusis, 5 mm. longis; stamina circiter 50, 

 longiora corollam dimidio longiora, basi tantum coahta, indistincte pentadelphia, 

 filamentis fihformibus glabris, antheris subglobosis; ovarium apice glabrum, 3-
