The specimens belonging to this natural order have been submitted to 
Professor Nees von Esenbeck of Breslau, who has kindly determined them, and 
transmitted to me the following names and characters of the new species. 
658. Menpoz1a puberula, Mart.—Salango. 
659. Exyrrarta apargiafolia, Nees ab E.—Gulf of Fonseca. 
660. Exyrrarta ramosa, Humb. et Kunth.—Acapulco. | 
661. ScrERocaLyx mezicanus, Nees ab E., gen. nov.—Acapulco. 
Cuar. Gen. Calyx grandis, coriaceus, basi brevi spatio tubulosus, profunde quinquefidus, 
laciniis eequalibus extus canaliculatis, estivatione quinquangularis, laciniis lateris interioris superficie 
valvatim conjunctis. Corolla crassiuscula, tubulosa, extus tomentosa, limbo 5-fido regulari laciniis 
planis. Stamina 4 ; anthere bilocellatee, cordato-oblonge, locellis parallelis muticis margine nudis. 
Ovarium ovatum, biloculare, loculis biovulatis; stylus filiformis; stigma oblique rostratum sive unila- 
biatum, basi superne impressum. Fructus latet. Inflorescentia: pedunculi versus apicem caulis 
axillares, oppositi, solitarii vel gemini, apice trifidi foliisque bractealibus caulinis similibus at minori- 
bus preediti. Pedunculi partiales firmi, infra apicem bibracteati, uni-triflori. Bractez partiales 
parvee.—Herba Mexicana, erecta. Genus Trichanthere et Macrostegie accedens, differt ab hac 
calycis equalis et crassi exstivatione et antheris, ab illa calyce longo nec imbricato antherisque 
haud ciliatis. 
S. Mexicanus. Caulis erectus, ramosus, pluripedalis, obtuse tetragonus, grosse lenticellatus, dense at 
subtiliter tomentosus, sicuti et petioli, inflorescentia et calyces. Folia caulis 7-8 poll. longa, 3 poll. lata, ovato- 
elliptica, basi acuta in petiolum pollicarem desinentia, apice cuspidato-acuminata cuspide obtusiusculo, integer- 
rima, supra subtusque (presertim in costis) puberula. Pedunculi folio breviores, rigidi, erecti. Folia floralia 
1-1} poll. longa, oblonga, petiolata. Pedunculi proprii patentes, longitudine petioli folii floralis. Bracteole 
infra apicem due, aliis spathulate aliis lineares, tomentose. Calyx pollicaris, laciniis lanceolatis acutiusculis 
utrinque tomentosis. Corollam explicatam non vidi (a/bam describit schedula adjecta). Stamina quod ad 
antheras, si pilos demis, 7ricanthere similia, Ovarium annulo lato cinctum, biloculare, quadriovulatum. 
662. ScoropoxyLum ¢erminale, Nees ab E., sp. n., suffruticosum, caule basi repente adscen- 
dente tetragono apicem versus laxe pubescente, foliis oblongo-ovalibus acuminatis basi acutis 
repando-crenatis tenuibus glabris costis subtus strigosis, thyrso terminali sessili parvo, bracteis 
calycisque laciniis subulatis scabris, capsula a medio superne 6-8-sperma.—Atacames. 
Quod ad inflorescentiam haud absimile est Stemonacantho Humboldtiano, sed reliqua sunt hujus generis. 
Caulis anguli acutiusculi sunt. Folia inferiora cum petiolo semipollicari 6-7 poll. longa, 2-24 poll. lata, obiter 
a.
