bracteatis ; sepalis lanceolatis, pilosis ; corolla breviter tu- 
bulosa, limbi lobis oblongis, apice rotundatis, campanulatim 
expansis ; antberis lineari-oblongis, exsertis ; drupa parva, 
pallida. — In India orientali, prow. Martaban, Madras, et

This, according to Dr. Wight, is a small, very branching 
shrub, growing on the sandy banks of rivers, like the two 
preceding species. The drawings of Wight and Hooker quite 
agree in all points of structm-e with the figures given by Mar- 
tins of the t;yq3ical species. The axils are 2-3 lines apart ; 
the leaves are 8-10 lines long, 3-3-^ lines broad, on a petiole 
^ line long ; the flowering branchlets are |-f inch long ; the 
sepals are lanceolate, canaliculate at the apex, 3 lines long; 
there is no disk ; the form and structoe of the ovary, style, 
fruit, and albuminous seeds as in the typical species. 
On the Ehretiace^. 
Eheetia. 
This genus, as arranged by DeCandolle, is very heteroge- 
neous, and requires redistribution, as it contains several dis- 
tinct groups easily recognized by good characters, especially 
by those founded on their carpical structure. After the exa- 
mination of all the plants within my reach, referred to EJiretia^ 
from the New World, I propose to retain in the genus only 
those species which are proximate to E. tinifoliaj Linn. Many 
of those belonging to. the Old World will probably be found, 
upon critical examination, to be foreign to the genus. I have 
not had leism-e to analyse them ; but among those which I 
have examined, some distinct forms have been noticed* -d- few 
from Australia and Asia have a fruit containing four nucules, 
each 2-celled and 2-seeded, with a particular organization ; 
others, again, have a bifid style, each obcuneiform branch 
bearing two distinct sessile stigmata ; but the placentation of 
the ovary is that of Ehretia and Rhabdia. 
The greater number of the Neogean species of Ehretia enu- 
merated by DeCandolle enter into the genera Bourreria and 
Creniatomia : these are distinguishable at a glance from Ehretia 
by their much larger, tubular, fleshy calyx, terminated by five 
teeth with thick tomentous margins, which are valvately closed 
in aestivation, and afterwards sometimes adhere so strongly 
together as to be separable with difficulty.
