cut or broken, but changing almost immediately to reddish - 
rusty-brown if the cut or fracture be transverse, not otherwise. 
Nut hard bony even, not rough or furrowed, with a slightly 
prominent suture up one side, ovate or elliptic, one-celled, con- 
taining a single loose narrow-elliptic kernel invested with a thin 
light-brown skin. Kernel pale-greenish internally ; its coty- 
ledons foliaceous, beautifully convolute, appearing in a trans- 
verse section like 2 leaves or laminae rolled together spirally. 
The fl. are produced profusely, but are rather dull and incon- 
spicuous, the light-gr. cal. -tube or germen and anthers pre- 
dominating over the small remote white wrinkled pet. Not- 
withstanding their profusion, very few fr. attain maturity, and 
that only after a very long period. In one instance the fr. of 
Dec. fl. remained in June in the same gr. immature but full- 
grown state w^liich they had attained in March, and did not 
ultimately ripen till Dec. following, i. e. a full year after their 
first formation. The convolution of the cotyledons has supplied 
an interesting fact in confirmation of the close alliance of this 
tribe of Rosacece to Calycanthacece (and so to Granatacece ) in- 
dicated long ago by Dr. Lindley. See Linn. Trans. 11. cc. This 
connexion with Granatacece (the Pomegranate) is curiously 
borne out externally by the habit and foliage. 
“ Buxo ” is properly the common garden Box ( Ruxus sem- 
pervirens L.), and is only occasionally or conventionally applied 
to the present pi. with the distinctive epithet u da Rocha.” 
The Medlar ( Mespilus germanica L.), “ Reaper cir a ” of the Por- 
tuguese, occurs here and there in gardens above 1500 ft., but 
is rare. The Japan Medlar or Loquat [ Eriohotrya japonica 
(Thunb.)] “ Reaper a de Japan,” introd. about 30 years ago, is 
now common, producing abundantly its gratefully acid amber- 
col. fr., which is about the size and shape of a walnut, from 
Nov. to April, from the level of the sea to 3000 or 4000 ft.
