following Plée, regard Buxus as the type of a distinct natural 
order f. 
*Engelhardtia chrysolepis, Hance in Ann. Sc. Nat. Par. ser. 4, xv. 
227. (=E. Wallichiana, Lindl., 8. chrysolepis, Cas. DC. in DC. 
Prod. xvi. ii. 142.—Engelhardtiz 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 E. Wallichiana, Lindl. 
*Myrica Nagi, Thunb.; 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. Not known out of 
the island. Found by the Rev. 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. 
Cup 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, 4. DC. in DC. Prod. xvi. 2. 110. ( 2 Castanea 
concinna, Champ.; Benth. Fl. Hongk. 319.) 
In an important memoir by Prof. (Ersted, of Copenhagen, 
* Apercu sur la classification des Chénes,’ 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 Cupulifere into two suborders, Quercine and Castanine, 
placing in the first, distinguished by having pendulous male 
amenta and the stigmas occupying the whole inner face of the

(I have seen no 9 ones) of my B. stenophylla, which J. Müller 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 excellent review of the 
genus :—Filamentis calyce dimidio v. vix duplo longioribus complanatis, ovarii 
rudimento calycis segmentis obtusis paulo breviore complanato apice parum 
dilatato subbilobo.
