 te"rminal very corhpact panicle : involucral bracts lanceolate, 

 hirsutc and purple-tipped : ray-flowers 6 to 8, with narrowly

 — Volcan de Agua, Dcpart. Zacatepequez, alt. 11000 feet,

 but differs in being stouter, with much more compact inflores- 

 cence, leaves very smooth above and dcnsely woolly bcneath,

Sknecio GiiiESBREC.HTii Hort. Hal. Regel {S, grandifoliiis 

 of authors, not Less.) — Specimens from Serraquitche, Depart. 

 Alta Verapaz, alt. 2500 feet, (y. D, 5. 1598), show that the 

 characters of the species must be made to include not only 

 ovate, but also elongated ovate or even obovate leaves, 

 hich are often acute at base as well as apex, and whose 

 margins vary from sinuate-dentate to cntire. These Guate- 

 malan specimens also show that the disk-flowers may be fcwer 

 than 10, most of the heads containing but 5 or 6. 



Senecio Ghtesbreghtti Hort. Hal. Regel, var. pauciilorus

 1000). S. Ghicsbrcghtii has 4 to 6 ray-flowers and 10 disk- 

 flowers ; while the variety has uniformly 2 ray-flowers and 

 3 disk-flowers.

 2 to 2. 5 cm. broad, rcadily falling off and leaving the stem 

 covcred with prominent scars : heads discoid, about 6 mm. 

 high, in terminal rather loose corymbose panicles: involucral

 accessory bractlets : disk-corollas about 0, deeply 5-lobed,
