Notwithstanding that the plants of Pomeous Rosaceae have undergone exami- 

 nation from several Botanists since the year 1820, when I first revised them, yet 

 I find so little original criticism upon the genera and their characters, that I am 

 tempted to avail myself of the present opportunity of offering a few additional 

 remarks : — 



Eriobotrya. It is not improbable that Pliotiiiia dubia maj' belong to this genus : it 

 varies witli three styles, and probably with a greater number. Nothing can decide 

 the point except its ripe seed, which I have never succeeded in procuring. Its habit 

 is that of Eriobotrya. Eriobotrya ? cordata, and -B. ohtusifulia do not belong to the 

 genus ; they are much nearer Cotoueaster, having subparietal carpels. But their 

 petals are longer than is usual in Cotoncastcr, and there is only one ovule in each cell. 

 I therefore think they may be safely separated as a peculiar genus, to which the name 

 of Hesperomeles (or Western Apple) will not be inappropriate. 



Hesperomeles. Calyx brevis, rigidus, valde apcrtus, 5-dentatus. Petala concava, 

 dentibus calycis longiora. Staniina 20, dentium calycis longitudine. CarpeUa 5, 

 calycis tubo adnata, glabra, augulis interioribus libera, unilocularia, ovulis solitariis ; 

 styli 6, distinct!, glabri. Fructus ignotus. Frutices peruviani. 



1. H. cordata^Eriobotrya? cordata. Lindl. 



2. H. oblonga ; foliis obloiigis rugosis supra glabris subtus ferrugineo-villosis, cymis lanatis 



foliis brevioribus. PerUy Mafheivs, no. 888. 



3. H. obtusifolia^EriobotryaobtusifoUa. D. C. 



i. H. cuneata; spinescens, foliis cuneatis apicc subtrilobis incisis supra nitidis utrinque 

 glabris, corymbis puboscentibus termiualibus foliis brevioribus, petalis calvis. Peru, 

 Matheivs, no. 517. Fructus ex descr. Mathewsii parvus rotundas ruber. 



Photinia. This must be divided into two sections, until an examination of the fruit of 

 the second section shall shew whether it is not rather a separate genus. 



Sect. 1. Euphotinia ; ovario complete blloculari. 



1. P. serrulata. Lindl. 



2. P. prunifolia (P. serrulata |8. Hooker et Arnott in Beechey's Voyage, p. 185.). Quite 



<Ustinct from P. scrriUata, in the leaves being glandular on the under side, and dif- 

 ferently formed, and in the flowers being much smaller. 



3. P. arbutifolia. Lindl. 



4. P. arguta (Wall. Qat. no. G72) ; foliis lanceolatis acuminatis argute serratis glabris, 



cymis sessilibus paucifloris lanatis, calycis dentibus obtusis membranaceo-marglnatis. 

 Pmidua, Wallich. Fructus ignotus. 



Sect. 2. Myriomeles ; ovario seviibiloeulari. 

 b. P. pustulata ; foliis obovato-lanceolatis acutis basi acuminatis supra medium serratis 

 Ipevibus utrinque glabris, corymbis calvis multifloris ramulis pustulatis. China prope 



Cantonein, Parkes. -Flares ignoti. Pomum semimaturum ovatum, pisi inagui- 



tudine, glabrum, calyce clauso coronatum. Pericarpium apice tantum liberum, char- 

 taceum, 2-locuIare ( v. abortu uniloculare). Semina 2-4, testa coriacea submucilagi- 

 nosti, acidi hydrocyanici gustu. Embryo compressus, radicula exserta. 



6. P. integrifolia. Lindl. (Wall, Cat. no. 6G9. cum fructu Stranvcesiie glaucescentis com- 



mixta) foliis ovalibus nitidissimis utrinque acuminatis glaberrimis, corymbis supra- 



decompositis densis glabris, floribus sessilibus. 1 doubt very much whether Dr. 



Blume's plant of tliis name from Java, is not quite a distinct species ; see Bijdragen, 

 p. 1103. 



7. P. eugenifolia ; foliis oblongis acuminatis integerrimis glaberrimis, corymbis supra- 



decompositis divaricatis tomentosis. Pundua, Wallich. 



Dubia. 



8. P. dubia. Lindl. P. bengalensis, X>o?i, is not distinct from this. 



Raphiolepis. There is an important mistake in the character of the fruit of this genus. 

 The seeds have not a thick leathery testa, as is represented in the Collectanea Bota- 

 nica, from imperfect materials. On the contrary the testa is tough, thin, arid mem- 

 branous. The embryo is spheroidal, with a distinct chalaza, and two plano-convex 

 cotyledons, within whose base the radicle lies concealed, as in Eriobotrya ! 



Cratcegus Imvis and villosa of Thunberg are probably referred with justice to Photinia ; 

 but I am altogether unable to judge, from Dr. Blume's short characters, where his 

 Mespilus spiralis, and Chinensis ouglit to be placed. P. Sieboldi of G. Don, the 

 Mesjnlus Sieboldi of Bhime, is stated by that author, upon the authority of Dr. 

 SieboM to be the Crata;gus villosa of Thunberg.
