herbs bearing 1-4 heads in a corymbiform cluster; leaves arising 
from a densely woolly crown. 
robably a monotypic Cuban genus, although Hoffmann refers 
here some little-known scapose African forms.

Characters of the genus; leaves spatulate or oblong- spatulate, 
acute or obtuse, entire, gradually narrowed below into a margine 
eat petiole, glabrous above, sparingly pubescent beneath, 
5-14 cm. long including the petiole, 1-2 oe wide, the lateral veins 
obscure; scape erect, puberulent . 1-5-3 . high, peduncles sub- 
tended by subulate. bracts ; involucre eee 8 mm. high; 
scales all erect, loosely imbricated in few series, pubescent and 
glandular, the outer triangular-lanceolate, the inner oblong to ob- 
long-lanceolate, acute; achenes 2.5 mm. long, glabrous, with a 
prominent basal callus; pappus tawny, 6 mm. long. 
Type locality: ‘¢In insula Pinorum.” 
Distribution: Cuba and the Isle of Pines. 
The status of the genus has long been doubtful. Its author rec- 
ognized its relationship to Verzonéa and included it in the same 
tribe. His principal reason for distinguishing it generically was 
the acuteness of the bases of the anthers. Grisebach, for the same 
reason, regarded it as related to the Inuleae, to which tribe he trans- 
ferred it. Bentham and Hooker placed it among the Vernonieae 
again, separating itfrom Vernonéa principally because of its scapose 
it. his feature, however, is shared by Vernonza acaulis, and 
the involucral characters of the two are much the same. Hoffman 
reduced the genus to a section of Verzonza, although quoting the 
original name for the species. All of these later authors have over- 
looked the uniseriate pappus, a character mentioned in Richard’s 
original description. Since in this paper the presence of two une- 
qual series of pappus-bristles has been taken as a criterion of Ver- 
nonia, Lachnorhiza has, for this reason as well as its other struc- 
tural peculiarities, been kept as a distinct genus.
