Page 1178, after Kuhnia paniculata, insert : 



la. Kuhnia leptophylla Scheele. Finely pubescent. Stems 1 m. tall or less, 

 often much-branched: leaf -blades linear, usually narrowly so, 1-6 cm. long, entire, 

 sessile: involucres 10-12 mm. high; bracts pubescent, the outer ones caudate-acumi- 

 nate: achenes 4-4.5 mm. long: pappus sordid. Differs from K. paniculata in the 

 larger heads and the caudate-acuminate outer involucral bracts. 



In dry soil, Arkansas to Texas. Summer and fall. 



Page 1228, after Aster exilis, insert : 



lOOa. Aster inconspicuus Less. Annual, glabrous or obscurely glandular in 

 the inflorescence. Stem mostly 1 m. tall or less, rather copiously branched above, 

 the stem and branches flexuous: cauline leaves mostly 1-1.5 dm. long; blades elliptic 

 to oblong, varying to broadest above or below the middle, acute, shallowly toothed, 

 those of the branches much narrower: heads much smaller than those of A. exilis and 

 A. subulatus: involucre campanulate, 3.55 mm. high; bracts linear-lanceolate to 

 narrowly linear: ray -flowers 20-30, more numerous than the disk-flowers; ligules 

 mostly pale lilac, about 2 mm. long. Differs from A. exilis in the numerous ray- 

 flowers with small ligules and from A. subulatus in the broad toothed blades of the 

 cauline leaves. 



In saline soil, Key West, Florida. Also in Cuba. All year. 



Page 1230, after Erigeron Bellidiastrum, insert: 



7a. Erigeron mode~stus A. Gray. Annual, finely, but somewhat roughly pubes- 

 cent. Stems 1-3 dm. tall, more or less branched at the base and above: leaf -blades 

 spatulate to linear, 1-3.5 cm. long, entire: involucres 1.5-2.5 mm. high; bracts his- 

 piduloua, the outer ones green, the inner broadly scarious-margined : ray-flowers 30-40 ; 

 ligules white: achenes flattened. Differs from E. Bellidiastrum in the smaller heads 

 ivith fewer ray-flowers and in the flattened achenes. 



On dry or sterile plains, Arkansas to Texas. Spring. 



Page 1231, after Leptilon Bonariense, insert : 



5. Leptilon subdecurrens (Sch. Bip.) Small. Stem and branches slightly 

 arachnoid with somewhat viscid hairs, 2-6 dm. tall: leaf -blades spatulate-cuneate to 

 oblong or lanceolate, 1.5-5 cm. long, sinuate-dentate or somewhat pinnatifid on the 

 lower part of the plant, partly clasping: heads numerous, in thysoid racemes or pani- 

 cles : involucres about 4 mm. high ; bracts linear-subulate to subulate, pubescent : 

 corollas of the disk-flowers with ovate-lanceolate lobes : ray-flowers with whitish minute 

 ligules. [Erigeron subdecurrens Sch. Bip.]. Differs from the preceding species of 

 Leptilon in the thinly arachnoid stem and branches, and the sinuate-dentate, partly 

 clasping leaf -blades. 



In moist soil, southern Texas to Arizona and northern Mexico. Spring to fall. 



Page 1233, after Baccharis Texana,, insert: 



la. Baccharis dioica Vahl. A much branched shrub 0.8-2.5 m. tall, with some- 

 what resinous-coated foliage. Leaves numerous; blades spatulate, often broadly so, 

 to obovate-spatulate, 1-3 cm. long: pistillate involucres with ovate obtuse outer bracts 

 and linear-lanceolate acuminate inner bracts: pappus about as long as the pistillate 

 corollas. Differs from B. halimifolia in the entire leaf-blades and the acuminate 

 inner involucral bracts. 



In hammocks along the shore of Biscayne Bay, Florida. Also in the West Indies. 

 Spring to fall. 



Page 1235, after PLUCHEA, insert: 



61a. SACHSIA Griseb. 



Perennial herbs. Leaves alternate, mostly basal: blades toothed. Heads erect, 

 scattered, in open corymbs. Involucre campanulate : bracts very unequal, the inner 

 much longer and somewhat narrower than the outer. Marginal flowers pistillate: 

 corollas filiform. Central flowers perfect: corollas narrowly tubular funnelform; 

 lobes ovate. Pappus a single series of slender bristles. Differs from Pluchea in the 

 scattered heads and the rigid involucral bracts. 



1. Sachsia Bahame'nsis Urban. Plants 1-6 dm. tall: basal leaves in a rosette; 

 fclades firm, spatulate, 3-7 cm. long; those of the stem-leaves much smaller: invo-
