indurata?, immutatas, facile separabiles, lanceolatas v. cuneatas,
inferne praster basim glabram lanata?, superne tomentellas, 3-4'"
longas. Receptaculum semiovato-conicum, 3-4'" altum. Calyx
luteus, semipollicaris, glaber ; limbus parte tubi pertenuis emergente
ter brevior ; tubi pars diu persistens circiter sesquilineam longa.
Basis styli tenuissimi denique defrangens. Germina pauca f•cun-
dantur. Caryopses conico-ovatas, acutas, linea paulo longiores,
villis perteneris undique sed basi saspe longius comptas.
Isopogon tridens.

Cand. Frodr. xiv. 280.

Flores etiam ín exemplis me examinatis desunt. Germina saape
abortiva. Tali modo mihi caryopses maturas deficiunt. Bracteas
involucri interiores 3-4'" longas, facile separabiles. Bracteolas basi
angusta truncatae.
Isopogon trilobus (Br. in Transact. Linn. Soc. x. 72 ; I. tripar-
tita, Br. Suppl. p. 8 e diagnosibus) nascitur me ipso observante
circum montes Stirlingii. Folia glaucescentia. Involucrum pauci-
seriale, receptáculo conico-cylindrico denique profunde alveolato et
tune glabro pluries brevius. Calycis tubus vix ultra bracteolas
emergens, inferne glaber, superne cum lobis flavido-sericeus ; lobi
linea paulo longiores. Bracteolas multiseriali-imbricatas, late cu-
neatas v. inferiores magis quadratas, dorso velu tino-tomentosas.
Caryopses conico-ovatas, apice attenuatas, basi longius superne
brevius villosas, paucas maturescentes. Varietas eloba, foliis rhom-
beo-cuneatis passim lanceolatis seu integerrimis seu antice late tri-
v. bidentatis occurrit ad Cape Riche et ad Thomas-Brook sinus
Great Bight ; Maxw.
Isopogon crithmifolius.
Ramulis sericeo-tomentellis, _/b/¿¿s trisectis, segmentis lanceolato-
vel cuneato-linearibus indivisis vel bi- vel trifidis, bracteis involu-
crantibus pauciserialibus mox patentissimis, receptáculo ovato-
cylindrico, bracteolis cuneatis subito brevi-acuminatis extus dense
tomentosis, calycis tubo glabro, parte exserta lobis apice barbellatis
