the lateral oblique, the terminal one somewhat larger, pilose, 
canescent beneath: peduncles filiform, chiefly twice exceed- 
ing petiole, cymes 2—5-flowered, pedicels not geniculate: 
sepals oblong, apex rounded: petals thrice longer (7), ob- 
tuse, yellow: flaments connate above ovary, edentate, the 
larger ones scabrid: capsule cano-villose, cells uniovulate or 
occasionally two-ovulate.— The most nearly related species, 
O. pentantka Jacq., differs by a less shrubby habit, pinnately 
trifoliolate leaves, acute sepals, dentate filaments, 3—4-ovu- 
late cells, etc. —San Miguel Uspantán, Depart. Quiché, alt.

Wimmeria eyeloearpa Radlk.—Rami hornotini, pedicelli, 
petioli foliaque (subtus densius, supra sparsim) pubescentia; 
folia majuscula, petiolo 8"" adjecto circ. 7^" longa, 3" et ultra 
lata, elliptico- vel ovato-lanceolata, acuta, vel abbreviata ob- 
tusa, immo suborbicularia, minutim glanduloso-serrulata, reti 
venarum pellucido laxiore instructa, pallide viridia; dichasia 
axillaria, quam folia breviora, 7—15-flora; fructus suborbicu- 
laris, vix brevior quam latus, diametro circ. 27", basi et apice 
excisus, alis membranaceis, styli brevis apice 3-stigma- 
tosi reliquis coronatus, e roseo pallescens.—OBSERV. Inter- 
media quasi inter W. pubescentem Radlk. (in Sitzungsber. 
k. bayer. Acad. 1878, p. 378) et W. confusam Hemsl. (W. .. 
pallidam Radlk. l. c. p. 379) et quidem quoad characteres 
anatomicos quoque: W. pubescens hypodermate fere continuo 
ad paginam foliorum superiorem instructa est, W. cyclocarpa 
supra venastantum, W. confusanullo. Ab una alteraque differt 
cellulis crystallophoris crystalla singula magna, ut in W. dis- 
colore et concolore, nec globoso-agglomerata foventibus. In- 
signis quoque stomatibus quodammodo elevatis. Uti omnes 
Wimmeriz species, quam rem 1885 observavi, excellit cellulis 
liberi quibusdam (et ramorum et foliorum) materia elastica foetis, 
qua materia £autckou£ certe affinis est et illam Paramerze ame
