it grows to be six or eight feet high, with numerous branches, 
which terminate in panicles of large, bright-blue, Borage-like 
flowers. The anther, style, and stigma are, at the time of flower- 
ing, covered by a curious calyptra, formed by five scales, which 
rise from the back of the anthers at the mouth of the tube of the 
corolla, free at the upper half and spiral, coming to a sharp point, 
firmly united to each other by interlaced cilia. The style comes in 
contact with the pollen of the anthers in passing up through this 
covering, but ultimately rises above this calyptra, forcing open 
the spiral portion, which, as soon as it has passed, closes on the 
style and stigma. The plant is perennial, with a sort of woody 
stem five or six inches in diameter (circumference?) near the 
ground. It rises readily from seed, and would be a great orna- 
ment to the gardens and shrubberies of Perth.” This proved to 
_ be, as was suspected, a 7richodesma, Br.; and the 7. Zeylanicum at 
this point of Australia attains its southern limit. Mr. Brown found 
it in Tropical Australia, and upon this species established his genus. 
It has been further gathered on the north-west’ coast of Australia 
by Mr. Bynoe (Voyage of the Beagle), at Port Curtis by J. Mac- 
gillivray, Esq., then in H.M.S. Rattlesnake, and by Mr. Fraser 
at Moreton Bay, in about the same latitude in Eastern Australia 
that the Irwin is on the west.* In all the warm parts of India 
this species is abundant, as well as in Madagascar, Abyssinia, 
and even in French Guiana. We have only reared a few plants 
in pots in a warm greenhouse, comparatively of small size; and 
if they ripen seed, we shall try in the open air, where they would 
probably flourish in summer, and greatly improve in the size of 
the flowers, as well as of stem and foliage. 
Duscr. An erect plant, with perennial root, and probably 
perennial sfem in the tropics, everywhere piloso-hispid, and fre- 
quently with white concretions at the base of the large setee ; but 
the nature of the hairs is very variable on different plants, so that 
Mr. Brown was led to make the remark :—“ Planta polymorpha 
preesertim strigarum et pubescentie copia.” Branches terete. 
Leaves lanceolate, varying much in width in different individuals, 
tapering at the base, but sessile. Racemes terminal, leafy, few- 
flowered, drooping. Calya of five, deep, lanceolate, acuminated 
lobes, as long as the corolla. Corolla rather deep and. fine blue, 
with five small white areolz or spots at the base; the shape is 
infundibuliform, the lower part of the tube contracted, above 
spreading, cup-shaped, in which cup the stamens are sunk ; the 
. Another species, as it is considered, is the 7. sericeum of Lindley, gathered 
by Major Mitchell in the subtropical interior, and by Mr. Collie at Flinders 
Bay, South-west Australia, It has altogether a different clothing to the whole 
plant, pubescenti-appressed and silvery, rather than rough with hispid hairs and 
tubercles.
