386 NATURAL HISTORY OF PLANTS. 
Next Embothrium come the three genera TZelopea, Lomatia, and 
Stenocarpus,' which have, speaking generally, the same structure in 
flower fruit and seed. But the first-named genus has terminal 
inflorescences, forming short capituliform racemes surrounded by an 
involucre of large colored bracts. The perianth often splits down 
one side only, its limb then forming a four-cleft lip ; the disk consists 
of a little subcircular glandular collar. Zomatia has with the same 
perianth, a disk formed not of a single piece but of three glands, one 
dorsal, the others lateral; the flowers form racemes with involucres, 
and the leaves are often pinnately toothed of laciniate. Stenocarpus 
has the flowers of Telopea or Lomatia, collected into umbels on a 
common peduncle, which may be axillary, terminal, or seated on the 
wood of the stem or branches. The follicle resembles that of 
Embothrium externally ; but the embryoniferous part of the ascending 
seeds is quite superior, the wing corresponding with the lower parts 
of the seed. Excepting some American Lomatias, all these plants 
come from Oceania, especially Australia. 
Knightia has the characters of the preceding genera, but the 
flowers are quite regular and the seeds are less numerous; for each 
cell only contains four ovules in two vertical rows. The seeds have 
the same direction as in Himbothrium ; their chalazal end is similarly 
prolonged. This genus is Oceanian. 
The two Australian types, Cardwellia and Darlingia, very near to 
one another, form distinct genera which must be classed in this 
series, because the anatropous ovules are numerous; but they are 
inserted on a more or less bowed horse-shoe shaped placenta with its 
concavity superior. 
The genus Buckinghamia, of which only one species is known, also 
Australian, has a pluriovulate ovary; and as its other characters are 
those of Grevillea, we are prevented from putting this last genus in 
a series distinct from Lmbothrium. — 
Grevillea’ (figs. 216-224) has regular or irregular flowers.’ In the 
first case the receptacle forms an inverted right cone, towards the

reasons, the bibliography of each genus will be 
found at its place in the following Genera.
