Dr. Lindley has probably correctly separated from Briobotrya cer- 
tain South American Pomacee, and constituted of them the genus 
Hesperomeles. The fruit, however, was unknown to him. Among 
my copious specimens T find ripe fruit on two species, and it is 
exactly as in Mespi/us, “Pomum turbinatum (seu globosum) 
apertum, ee endocarpio osseo :” the five osseous endocarps 
are indeed quite exposed to view, and are accurately figured so in 
both the species to which I allude, viz., Mespilus lanuginosa and 
M. heterophylla, by Ruiz and Pavon. It thus becomes a question 
how far they are rightly separated from that genus. The habit of 
the two plants now mentioned are distinct from Mespilus, but rather 
on account of their usually humble growth and coriaceous persistent 
leaves, than from any other character. Mespilus stipulosa, H.B.K., 
which I have from Loxa, may perhaps unite the two. Hesperomeles 
(Mespilus) /anuginosa, R. et P. Fl. ined. t. 425 a., I possess, with 
leaves as large as Osteomeles latifolia, H. B. K. Lc. t. B54 (H. 
cordata, Zind/.), and other specimens with leaves as small, an 
rusty-coloured beneath, as Osteomedes Ai ee of Humbo dt, and 
oblonga of Lindley ; all of which may, I think, be fairly recorded 
inches long; while, from great elevations, I have specimens like 
the variety here figured, with leaves less than half the size now 
represented. nije a Jameson describes the fruit (about the 
size of a pea) as esc
