Latcura differs from the preceding sections or subgenera 
by a one-ranked pappus of several permanent radii or 
pieces, of which two are large, opposite, filiform and 3-cor- 
nered, the rest small and paleaceous (chaffy); as well as 
by a calyx higher than the disk of the corolla and com- 
posed of regularly imbricated close-pressed leaflets, each 
of which is surmounted by a large recurvedly spreading 
appendage resembling the leaves of the plant. There are 
three published. species that belong here: 1. elegans, the 
Hewtanruus linearis (vol. 7. fol. 523.) of this Register, of 
the synonymy of which M. Cassini seems to have had only 
an uncertain knowledge: 2. bicolor, the Heiantuus angus- 
_ tifolius of Linnzeus: 3. microphylla, the Heutanraus micro- 
phyllus of Kunth. (Vid. nov. gen. et spec. 4. 220. t. 375.). 
The genus Vicurera of Kunth is said by M. Cassini to 
differ from his Harparrum and Lerexra only by its one- 
ranked calyx and elevated conical receptacle. He suspects 
moreover that Henanruus parviflorus of Kunth, with a ca- 
lyx very near to that of Vicurera, but a pappus and recep- 
tacle of the true HruAnruus, may form a fourth subgenus; 
for which however he proposes no name. ; ;
