COMPOSIT 323 
and often tortuose and more or less clavellate bristles: of the 
pistillate of usually more numerous and fine bristles. 
Trib. ii, Inuloidex Cass. An. Sci. Nat. 1829, 20. Heads 
heterogamous, radiate or discoid with fertile flowers filiform or 
ligulate; or sometimes homogamous and tubuliflorous. Anthers 
sagittate, and the base of the lobes produced into more or less of a 
tail (caudate) or other appendage. Style-branches of the herma- 
phrodite flowers filiform or flattish not appendaged: the stigmatic 
lines running to or vanishing near the roundish or truncate tip, 
which is at most papillose or somewhat penicillate. Style of stam- 
_ tnate-sterile flowers commonly entire. Pappus usually capillary or 
none. Involucre commonly dry or scarious, rarely foliaceous. 
SUBTRIBE I FILAGINEX. Bracts of the involucre mostly thin 
and secarious. Receptacle with scales of various texture, enclos- 
ing or subtending the fertile flowers or achenes: pistillate flowers 
with filiform truncate or 2-3-toothed corollas. 
* Achenes gibbous and compressed: corolla and style lateral; pap- 
pus none. 
25 Micropus Fertile flowers few and in a single series on the short recep- 
tacle, included in the laterally compressed very gibbous scale of the 
receptacle which strictly encloses the achene. 
** Achenes straight or slightly oblique: corolla and style terminal. 
+ Chaff loosely enclosing the aehene: central flowers sterile 
26 Stylocline Fertile flowers 5-10 or more, in two or more series on a 
cylindrical or columnar receptacle, their chaff thin, saccate or boat- 
shaped: pappus of few caducous bristles to the sterge flowers or none. 
27 Psilocarphus Fertile flowers numerous, in several series, on a globu- 
lar receptacle, each in an obovate turgid membranaceous and reticu- 
lated chaff: pappus none... 
+ + Chaff more open, hardly enclosing the achenes: fertile flowers 
in more than one series; central flowers sometimes fertile. 
— 28 Hesperevax Receptacle villous, its centre elongated inte a narrow 
column: achenes pear-shaped, flattened parallel to the subtending 
chaff: pappus none. 
SUBTRIBE II GNAPHALIE®. Bracts of the involucre all thin and 
scarious, often pearly, persistent. Receptacle naked. Floccose- 
woolly herbs. 
29 Antennaria Heads completely diccious, the staminate with undivi- 
ded style, and bristles of the pappus thickened or barbellate at the 
apex: pappus of the pistillate flowers slender and united at the base. 
80 Anaphalis Heads incompletely dicecious: staminate heads with a 
few hermaphrodite but sterile flowers in the centre: bristles of the 
pappus all separate, those ot the sterile flowers little thickened upward. 
$1 Gnaphalium Heads all heterogamous: pistillate flowers very numer- 
ous, in more than one series; hermaphrodite fertile ones fewer, in the 
centre: bristles of the pappus slender, not thickened upward.
