EAST-ASIATIC COEYLACEiE. 367 



cotyledonar structure. "^ My son Alfred gathered it at Fu cliau. I do 

 not know whether it occurs further south. 



12. Castanopsis costata, A, DC. — Involucris (aculeis exclusis) 15 

 lin. diametro depresso-globosis extus ferrugineo-tomentosis intus 

 sericeo-tomentosis demum in valvas plures (8-10 quantum ex speci- 

 mine dijudicare liceat) dehiscentibus densissime echinatis aculeis e 

 basi robusta semper ramosis 6-8 lin. longis acutissimis ferrugineo- 

 tomentellis ipso apice calvis, nucula involucrum implente extus 

 tenuiter sericea. 



The nut in the solitary fruit I have been able to dissect had the 

 cotyledons too much decomposed for analysis. The fruit, however, is 

 now, I believe, for the first time described. My specimens are from the 

 Leiden Museum, and from my kind correspondent Dr. Schefi'er. The 

 aculei in this group, so far as my own observation extends, are remark- 

 ably constant in shape and length. Hence, unless wrongly-named fruit 

 has been sent me as that of C. costata (which I have no reason to suppose 

 is the case), I cannot but think that C. costata, (3. hancana, Scheff. ! is 

 a distinct species. Dr. Scheffer himself remarks of it, " Costularum 

 numero necnon aculeis multo robustioribus a C. trisperma bene differt."t 

 But, though these aculei are broader and flatter, they are much more 

 like those of G. trisperma, Scheff. ! than they are to the needle-shaped 

 ones of the typical C. costata, as I have described them above. 



13. Castanopsis [Eucastanopsis) tibetana, sp. nov. — Ramis pur- 

 pureis glabris, foliis 7-9 pollicaribus petiolo glaberrimo poUicari 

 oblongis basi cuneatis apice cuspidato-acuminatis supra medium calloso- 

 serratis valde coriaceis supra vix lucidulis glaberrimis pallide marginatis 

 subtus opacis fulventi-lepidotis costulis inutroque latere 12-15 validis 

 subtus cum costa prominulis pallidis sub angulo 50° egressis reteque 

 venarum conspicue elevato, involucro globoso monocarpo diametro ses- 

 quipollicari aculeis compositis acicularibus varie curvatis brunneis 

 tomentellis densissime echinato in valvas 4 sequales dehiscente intus 

 praeter cicatricem glabram totum fundum occupante fulvo-sericeo, nuce 

 depresso-globoso 9 lin. diametro 6 lin. alta pallide brunnea lucida 

 tomento fulvo-sericeo deliquescente tectas hilo carpico magno ruguloso 

 glaberrimo opaco. 



Specimen debeo humanitati Rev. G. E. Moule, decerptum m. 

 !N'ovembri, 1874, ex arbore ad monasterium Lin yin, in vicinia urbis 

 Hang chau, prov. Che kiang metropoleos, culta. (Herb, propr., no. 

 18914.) 



Mr. Moule describes this as a tree with laurel-like foliage, as hand- 

 some as that of the evergreen Magnolia, and edible fruit. According 

 to the testimony of the Chinese monks, who call the tree Si leih, 

 " Chestnut from the West," it was brought from Thibet, and they say 

 the only specimens in the province are at that convent and in Pu tii 

 Island. Its nearest affinity is with C. costata, A. DC. 



14. Castanopsis {Eucastanopsis) Falconeri, sp. nov. — Ramulis 

 angulatis nigricantibus glabratis, foliis elliptico-lanceolatis integerrimis 

 basi cuneatis apice acuminatis 4-7 poll, longis 2-2^ poll, latis petiolo 



* Oersted (Recherches, &c., 21) erroneously assigns " cotyledones intricato- 

 plicatae " to all the species of this section, though those of the Japanese tree 

 are correctly described by Zuccariui (Fl. Jap,, 10) as "plane sibi incumbentes."
