clothed with starry hair, sometimes rough from prominent glands; the indument not very variable in 
the species. Leaves all alternate or fasciculate, constantly simple. Pedicels variously bracteolate, 
solitary, geminate, ternate, corymbose or umbellate, rarely racemose or (in Chorilsena) cymose. Petals 
generally longer than the calyx, white, pink, yellow, rarely blue or dark-red or green, spreading, 
sometimes connivent. Filaments smooth or hairy, seldom glandulous-tumescent at the apex, longer 
or shorter than the corolla. Anthers usually subcordate, with or without an appendage. Carpels 
blunt or rostrate. Placental membrane usually ovate, acuminate. Seeds frequently black.—Crowea,

It has been a subject of much enquiry and reflection of the author, in what manner the beautiful 
plants constituting the genera Eriostemon, Pliebalium, Philotheca, Crowea, TJrocarpus, Microcybe, 
Chorilsena, Asterolasia, Geleznovia, Sandfordia, Drummondita, should find their most natural arrange¬ 
ment ; for they are linked together by so close affinity that only a solitary character or the combi¬ 
nation of few uncertain notes distinguish them, the formerly adopted limitations having in most 
instances by the access of novel species been annihilated. It has been regarded therefore on this 
occasion as advisable to congregate the whole under Eriostemon, although this generic name agrees 
only with part of the species. The distinction from Boronia is through the Tasmanian E. virgatus, 
which produces flowers with four-cleft calyx, four petals, and eight stamens, reduced solely to the 
disposition of leaves, which are in Eriostemon never opposite, and in Boronia never all alternate, 
although, particularly in the division Zieria, some of the upper leaves are alternate. The subgenus 
Cyanochlamys, adopted by Bartl. (Lehm. PI. Preiss. i. 171), comprises only a few South-West Australian 
species remarkable for blue flowers, including E. spicatus, Rich. (E. effusus, Turcz.). 
Whether E. corymbosus (Lab. Sert. 58, t. 58), from New Caledonia, really belongs to this genus 
remains, although it shows considerable resemblance to E. squameus, to be ascertained, since in the 
otherwise excellent figure and description quoted neither mention is made of the embryo nor of the 
nature of the endocarp. Beyond the cymose inflorescence and the curious foliage, which reminds of 
Lasiopetalaceous plants, nothing remains to separate Chorilsena from Eriostemon, inasmuch as the 
large sepals of Eriostemon phylioides render the analogous character in Chorilsena of no avail. 
Diplolsena differs from Eriostemon chiefly in the inflorescence, in its scale-like petals, and in the 
development of a floral involucre consisting of bracts and bracteoles; by the suppression of the calyx it 
is not distinguished, since the subgenus Asterolasia is likewise devoid of the calycine envelope. The 
D. Dampierii, of which D. grandiflora seems a mere variety, was brought from the vicinity of the 
Murchison River by Mr. Aug. Oldfield. 
Sect. I. Crowea. 
Leaves glabrous. Pedicels axillary, solitary. Sepals small, blunt. Petals persistent, generally 
red or white, convolute-imbricate in aestivation. Stamens shorter than the corolla. Filaments fringed, 
free or coherent. Anthers terminated by a bearded long appendage. Stigma simple.
