N at. O rd. LIV. CONVOLYULACEÆ.
A considerable number o f plants o f th is Order inhabit Australia, bu t ow in g to the rapid fading o f the
corolla o f many o f the tropical species, th ey have been either n eg le cted or preserved in a state unfit for
e x amination; thu s, o f fifty-three species described in Brown’s ‘ Prodromus,’ many, especially o f Ipomoea and
Convolvulus, are unknown to us ; and o f about an equal number o f wbich we have specimens, there are not
a few that are undeterminable, partly owing to the briefness o f the diagnoses in th e ‘ P rodromus,’ and
partly to the specimens b e in g in an imperfect state. Probably there are about six ty known Australian species,
by far the greater majority o f which are tropical, and some o f them common to many parts o f th e globe.
Am on gst the most conspicuous o f these are th e C a ly steg ia Sepium and S oldan e lla, which are found in
almost all temperate r egions o f both th e northern and southern hemispheres ; Ci-essa Crética, D ichondra re p
e n s , and several species o f E vo lvu lu s, which inhabit mauy tropical countries o f th e Old and N ew YYorld;
aud lastly, various species o f P h a rb itis , Ipomoea, and B a ta ta s , which are common E a s t In d ian and P o ly nesian
plants. Altoge th e r, fully one-third o f th e Australian Convolvulaceæ are fouud in other parts o f the
g lo b e ; and one genus alone, W ilsonia, is confined to th a t con tin en t and Tasmania, and to th e south
and especially south-we st coast.

Only four or five Austrahan species of this genus are known : they are prostrate or rarely twining herbs, with
generally müky juice, alternate leaves, and handsome, campanulate flowers.— Calyx five-lobed, with smaD bracts at
its base or none. Corolla between infundibuhform and campanulate, witb five broad lobes and a pHcate æstivation.
Stamens nearly equal, shorter than the limb of the coroUa. Ovarg two-celled, ivith four ovules, a simple style, aud
two linear stigmas. (Name, an ancient one, derived fi-om the twining habit of the species.)
