I am not quite certain wbetbcr Dr. Secmami's plant is the same as Orsted's, not having seen an 
authentic specimen. However, it quite agrees with the short and somewhat incomplete diagnosis given by 
Eentham 1 c ■ but the flower-heads are said to be larger than in JS. capUUpcs, Benth. 1. c. no. 58, which 
has the capit^a scarcely U line long ; in our species indeed they are not of a greater size. Besides 
this difference I am not doubtful about its identity. The leaves of our plant arc 5-G bnes long and 
broad, most of them opposite, the uppermost much smaUer, alternate, the branches being likewise op- 
posite, forming a lax panicle.

(1853). Volcano of Cbiriqui, Veraguas. 
This little plant is somewhat dubiouB. It agree, partly with Bentham's brief diagnosis, but the 
capitula are not forty- to fifty-flowered, as stated by that botanist, they contain no more than twenty-eight 
to thb-ty flowers. The lower leaves of our specimen are fallen oif ; the upper are somewha rhombic-lanceo- 
late or oblong, 6-10 lines long. 2-3 lines broad, the lowest opposite, the upper mostly altema e, erenate- 
serrate, and somewhat scabrous; the long, capillaeeous, monocephalous peduncles form a very lax panic e, 
not so branching as in the preceding species, which however nearly approaches it; the flower-liead.
