MR. J. MIERS ON THE HIPPOCRATEACEÆ OF SOUTH AMERICA. 848 
branchlets, 2 lines long, are divided dichotomously, with other branches rapidly dimi- 
nishing, with short heads of flowers in each dichotomy, so that the inflorescence appears 
to consist of several agglomerated heads: the flower expanded is 24 lines in diameter, the 
pedicel being 1 line long. The petioles, PARC. and all parts of the flowers are 
filled with white spiral threads.

patentissime oppositis, subvirgatis, tenere teretibus, striolatis, subcorrugulatis, 
glabris : foliis lanceolato-oblongis, imo valde acutis, superne sensim attenuatis, apice 
acute acuminatis, serrulatis, dentibus rotundatis mucronato-cuspidatis, supra pallide 
viridibus, subtus subrufescentibus, nervis areuatim nexis venisque transversis valde 
reticulatis prominulis, opacis, sub lente minutissime granulato-punctulatis; petiolo 
tenui, anguste canalieulato, subtus corruguloso, limbo 15-15-plo breviore; stipulis. 
deciduis; paniculis axillaribus et terminalibus, folio dimidio brevioribus, flavo- aut 
rufulo-tomentosis, divaricatim dichotome divisis, cum ramulis 2 brevissimis in dicho- 
tomiis, ramulis ultimis subcongestifloris; floribus brevissime pedicellatis ; bracteolis 
ovatis, ciliatis ; petalis lineari-oblongis, acutis, utrinque flavide tomentellis, intus 
barbatis; disco elevato, imo paululo inflato, rufo-velutino; filamentis latis, sub- 
reflexis, glabris; stylo obtuso, brevi, exserto ; ovario 3-gono, cum lobis adscenden- 
tibus: eapsulis (sec. cl. Kunth) 3, subrotundo-ovatis, imo connatis, patulis, plane 
compressis, singulis 4-spermis, seminibus immaturis parvis, compressis, ovato- 
oblongis, erectis. In Mexico: v.s. in herb. Mus. Brit. (Pavon). 
This species is readily distinguished by its lanceolate leaves. According to Kunth, 
the leaves are 2-44 in. long, 8-11 lines broad, on a petiole of 4 lines: in Pavon's spe- 
cimen they are 5-7 in. long, li to lj in. broad, on a petiole 5 lines long: its axillary 
flowering branches, 5 in. long, bear only two leaves 3 in. long, with one terminal and two 
lateral panicles, whose peduncles are 1j in. long, their opposite primary branchlets are 
6-9 lines long, the rest shorter, with extremely short pedicels and subglomerated flowers. 
The flower expanded is 2l lines in diameter, the disk is $ line high and broad. The 
entire plant and inflorescence, as in many other species, is filled with numerous white 
spiral threads.
