*EngeUiardtia chrysolepis, Hance in Ann. Sc. Nat. Par. ser. 4, xv. 



227. (=E. Wallichiana, Ldndl., 0. chrysolepis, Cas. DC. in DC. 



Prod. xvi. ii. 142. — Bngelhardtise sp., Benth. Fl. Hongk. 318.) 

 In the Happy- Valley woods, but not common. Not known 

 out of the island. The number of stigmas and the golden scales 

 of the fruit and inner perigone seem to indicate this as distinct 

 from the Singapore U. Wallichiana, Lindl. 



*M3rrica Nagi, Thmb.; Cas. DC. in DC. Prod. xvi. 2. 151. ( = M:. 

 rubra, Sieb. and Zucc. ; Benth. Fl. Hongk. 322.) 



32. Quercus Irwinii, Hance in Ann. Sc. Nat. Par. ser. 4, xviii. 229 ; 

 A. DC. Prod. xvi. ii. 84. 

 In the Happy- Valley woods, very rare. Kot known out of 

 the island. Pound by the Eev. J. J. Irwin, D.D., and myself, 

 in fruit, in November 1862. 



*Quercus Hancei, Benth. ; Hance in Ann. Sc. Nat. Par. ser. 4, xviii. 

 230 ; A. DC. Prod. xvi. 2. 96. 

 Ciip corky, hemispherical, about 2 lines long, silky inside, and 

 with greyish scale-like pubescence outside, with concentric rings 

 repand and shortly toothed at the edge, so that at first sight 

 they look like distinct scales. Nut much exserted, ovoid, 7 lines 

 long, pale brown, with a protuberant umbo. Leaves not reticu- 

 late when fresh, but only after drying. 



*Castanopsis concinna, A. DC. in DC. Prod. xvi. 2. 110. ( = Castanea 

 concinna. Champ. ; Benth. Fl. Hongk. 319.) 

 In an important memoir by Prof. CErsted, of Copenhagen, 

 ' Aperfu sur la classification des Chenes,' published in 1869 as 

 an accompaniment to a posthumous work of Prof. Liebmann's, 

 illustrated with fine plates, on tropical American oaks, he di- 

 vides Cupuliferae into two suborders, Querciase and Castaninse, 

 placing in the first, distinguished by having pendulous male 

 amenta and the stigmas occupybig the whole inner face of the 



t I avail myself of this opportunity to note the structure of the S flowers 

 (I have seen no $ ones) of my B. stenophylla, which J. Miiller says I have not 

 distinguished by specific characters; this is owing to my not having known 

 where to look for these, until the appearance of his exceUeut review of the' 

 genus : — Filamentis colyce dimidio v. vix duplo longioribus complanatis, ovarii

 dilatato subbilobo.
