Colvillea racemosa. It is a tree 40 or 50 feet high, with 
tender and brittle wood. The extremities of the branches 
bear long racemes of velvety blossoms, of a fine red colour: 
the calyx is globular, tomentose, 2-lobed; the upper lobe 
large, straight, divided in 3 or 4 teeth, marked with as many 
nerves; the lower one smaller, linear-lanceolate: corolla 
pentapetalous: vexillum of a singular shape, reniform and 
convolute, 7. e. rolled spirally inwards: carina pubescent, 
longer than the alee, of 2 petals: al@ oval-lanceolate: stamens 
10, their filaments free, unequal, downy at the base: ovary 
subsessile, compressed, lanceolate: style filiform: stigma sharp- 
pointed : legume bivalved, straight, many-seeded : seeds ellip- 
tical, compressed. 
It was in 1824, that M. Bojer first saw this magnificent 
tree, which he found, bearing fruit only in the Bay of Bom- 
betoe in Madagascar; and from the seeds which he then 
collected, all the individual plants, now growing in Mada- 
gascar, are reared. 
Another plant which M. Bojer has made known to the 
Society, belongs to the Genus Barreliera.* It grows in fields 
in the province of Saccalaves at Madagascar, whence M. B. 
introduced it to the gardens of this country, where it thrives 
prodigiously and flowers almost all the year. Its yellow 
flowers, crowded in thick spikes and partly covered with 
coloured bracteas, its glossy green leaves, marked with red 
nerves, render it a peculiarly desirable species. M. Bojer 
has named it Barreliera monostachya. — 
The third plant is a species of Cassia, which grows spon- 
taneously in stony barren spots around the city of Tannana- 
rivou, the capital of the province of Emirena in Madagascar. 
This Cassia is remarkable for its fibrous, capillary roots, 
which bear at their extremities little fleshy tubercles. The 
* M. Bojer deems it more conformable to Etymology thus to spell this 
name, which is a Genus dedicated to Father Barrelier. It is the Barleria 
= authors.
