introduced. It is named in honour of J. C. Philibert, the author of some botanical works published about tlie 
beginning of the present century. 
1.— PHILIBERTIA GRAND IFLORA Hooh. 
Syhonyme. — P. gracilis D. Don. 
Engravings. — Bot. Mag., t. 3618 ; Bot. Reg. for 1843, t. 13 ; 
Sweet’s Brit. Flow. Gard., 2nd series, t. 403 ; Paxton’s Mag. of Bot.,

THE LARGE-FLOWERED PHILIBERTIA. 
Specific Character. — Leaves deeply cordate, acuminate, suh- 
tomentose. Corolla three times as long as the calyx, campanulate, 
externally hairy, smooth within. Crown double ; exterior one annular, 
entire | interior one composed of five fleshy leaf-like segments, each 
having a short mucro near the apex. 
Description, &c. — This is a very pretty twining plant, the seeds of which were sent from Buenos Ayres by 
Mr. Tweedie in 1835. It varies very much in the colour of its flowers, some being of a pale yellow, and others of 
various shades of crimson and dark brown. It also vaiies much in the quantity of down which covers it, the wild 
specimen which was sent over being quite woolly, while some of the specimens grown in England are only very 
slightly tomentose. It should be grown in a friable mould mixed with sand, the soil not being sifted but merely 
broken finely and mixed with the hand. The pots should be well drained, as the plants require to be kept nearly 
dry during the season of rest. When the plant is kept in a hothouse or in too warm a greenhouse, it is very apt 
to be attacked by the red spider. 
CHAPTER XLIV. 
GENTIANACE^ Undl. 
Essential Character. — Calyx divided, inferior, persistent. Corolla l tliem. Ovary composed of two carpels, one or two-celled, many-seeded, 
monopetalous, hypogynous ; limb regular, its lobes the same number Style one. Stigmas two. Fruit a capsule or berry. Seeds small ; 
as the divisions of the calyx, generally five. Stamens inserted upon testa single. Embryo minute, in the axis of soft fleshy albumen, 
the corolla, equal in number to the segments and alternating with | 
'Description, &c. — Most of the plants contained in this order are natives of cool, or at least temperate climates, 
and only very few require a greenhouse in Great Britain. 
GENUS I. 
CHIRONIA Lin. THE CHIRONIA. 
Un. Syst. PENTANDRIA MONOGYNIA. 
Generic Character. — Calyx five-parted. Corolla salver-shaped, i Style declinate, a little longer than the stamens. Stigma capitate, 
with a narrow tube and a spreading limb, which is much longer than assurgent. Capsule ovate, one-celled, two-valved. Seeds numerous, 
the tube. Stamens five ; filaments broad, rising from the top of the ((?. Don.) 
tube of the corolla ; anthers connivent, at length spirally twisted. | 
Description, &c. — There are several species in this genus and in the genus Roslinia, which has been formed 
from it, all of which are very ornamental ; but the limits of the present work will only admit of one species being 
described. The word Chironia is derived from the Centaur Chiron, from the plant being anciently used in 
medicine, which was one of the sciences he taught to his pupil Achilles.
