Minuria annua, Tate, m.s. 
In the following description of a new plant, I have embodied 
the results of a microscopic examination of the floral parts, which 
might have been omitted if the generic location did not admit of 
a doubt; but whereas the plant presents a new departure for the 
genus in respect of habit, it becomes desirable that those features 
relied on in the classification of the genera of the Tribe Asteroidez 
should be correctly defined. 
A dwarf glabrous annual, erect, up to one centimetre, slightly 
branched at the base; branches slender, compressed. Leaves 
somewhat fleshy, 30 to 35 mm. long, alternate; sessile slightly 
dilated and thin below, narrow linear above, obtuse at the tips. 
Flower-heads erect, singly and laterally disposed along the 
branches, leaf-opposed, about 7 mills. broad in the longer 
diameter ; pedunculate on stalks up to 4 mills. long. Jnvolwere 
campanulate ; receptacle slightly convex, ellipsoid in marginal 
outline (the diameters as three to four). Aracts about 16, chiefly 
in one row with a few small exterior and basal ones, narrow- 
oblong, narrowed at the base and slightly dilated upwards, 
rounded at the tips; of thin texture, firm, but not coriaceous; 
medially green, with a translucent margin all round, which is 
more or less laciniate, or sometimes ciliate at the summit. 
Ray-florets 20 to 30 anantherous. Corolla-tube as long as the 
pappus (3 mills.), filiform, green, the ligulate blade yellow, at first 
linear, expanding upwards into a spathulate or narrow oblong 
tip, nearly as long as the tubular portion. Pappus well-developed, 
3 mills. long, and slightly exceeding the involucre, consisting of 
about 25 filiform bristles, not at all dilated at the base, equally 
strongly and closely denticulated throughout. Style linear- 
lanceolate ; style-branches, a little longer than the style, filiform- 
cylindric (apparently without papille), included within the 
corolla-tube, or but slightly -exsert. Archenes fertile, narrow- 
elliptical, attenuated upwards and there truncate; 2 mills. long, 
silky-hairy, especially on the margins. 
Disk-florets bisexual, about 15 in. each head. Corol/a tubular, 
filiform, but widening upwards ; five-toothed (the segments short, 
broad, and acutely triangular). The pappus bristles more or less
