Question: Epidendrum and Platycodon, are genus of which species?
Context: "Epidendrum" subsect.  "Paniculata" is a subsection of section "E".  sect.  "Planifolia" of subgenus "E".  subgen.  "Epidendrum" of the genus "Epidendrum" of the Orchidaceae (orchid family).  Plants of "E".  subsect.  "Paniculata" differ from the other subsections of "E".  sect.  "Planifolia" by producing paniculate inflorescences.  In 1861, Reichenbach recognized eighteen species in this subsection.  From this group, Kew recognizes seventeen species (Page numbers are from Reichenbach): Epidendrum macrocarpum, commonly known as "Epidendrum schomburgkii", is a species of orchid in the genus "Epidendrum", and the largest-flowering crucifix orchid species.  Reichenbach thought that "E. fulgens" and "E. schomburgkii" var.  "confluens" were both synonyms for this species. Epidendrum , abbreviated Epi in the horticultural trade, is a large neotropical genus of the orchid family.  With more than 1,500 species, some authors describe it as a mega-genus.  The genus name (from Greek "ɛpɨ, epi" and "δένδρον, dendron", "upon trees") refers to its epiphytic growth habit. Epidendrum difforme (the "Differently Formed Epidendrum") is a species of orchid in the genus "Epidendrum".  In 1861, Müller classified this species in the subsection "Umbellata" of the section "Planifolia" of subgenus "Euepidendrum" of the genus "Epidendrum". Epidendrum anceps, literally the "two-edged upon a tree," a species of epiphytic orchid in the genus "Epidendrum", is sometimes known as the Brown "Epidendrum or Dingy-flowered "Epidendrum. Platycodon grandiflorus (from Ancient Greek πλατύς "wide" and κώδων "bell") is a species of herbaceous flowering perennial plant of the family Campanulaceae, and the only member of the genus Platycodon.  It is native to East Asia (China, Korea, Japan, and the Russian Far East).  It is commonly known as balloon flower (referring to the balloon-shaped flower buds), Chinese bellflower, or platycodon. Epidendrum" subsect.  "Tuberculata is a subsection of the section "Schistochila" of the subgenus "Amphiglottium" of the genus "Epidendrum" of the Orchidaceae.  This subsection differs from the subsection "Integra" in that the margins of the trilobate lip are dentate or lacerate.  This subsection differes from the subsection "Carinata" by possessing a callus, or tubercule on the midlobe of the lip.  In 1861, Reichenbach recognized 22 species in this subsection.  Many, but not all, have since been brought into synonymy with "Epidendrum secundum".  (Page numbers refer to Reichenbach, 1861.) Epidendrum" subsect.  "Racemosa is a subsection of section "E".  sect.  "Planifolia" of subgenus "E".  subg.  "Epidendrum" of the genus "Epidendrum" of the "Orchidaceae" (orchid family).  Plants of Racemosa differ from the other subsections of "E".  sect.  "Planifolia" by producing inflorescences which are racemes.  In 1861, Reichenbach recognized 26 species in this subsection.  These names correspond to 25 species currently recognized in the "World Checklist of Selected Plant Families" (page numbers refer to Reichenbach 1861): Epidendrum subsect.  Spathacea is a subsection of the section "E".  sect.  "Planifolia" of the subgenus "E".  subg.  "Epidendrum" of the genus "Epidendrum" of the Orchidaceae.  Like the other subsections of "E".  sect.  "Planifolia", the species of "E".  subsect.  "Spathacea" are characterized by a sympodial growth habit without pseudobulbs, a lack of any spathes or sheathes covering the base of the racemose inflorescence, and by flat (not round) leaves.  The species categorized in "Spathacea" differ from the members of the other subsections by having large floral bracts, which make the inflorescence resemble a strobilus.  Reichenbach originally placed eight species in this subsection (page numbers refer to Reichenbach 1861): The section Epidendrum" sect.  "Sarcophylla is a subsection of subgenus "E".  subg.  "Epidendrum" of the genus "Epidendrum" of the Orchidaceae.  In 1861, Reichenbach recognized one species in this section:
