 Epidendrum maduroi belongs to the E. albertii
group (Hagsater 1999a). Plants of E. maduroi have
probably been confused as both E. adnatum and E.
lankesteri, described from Costa Rica. Epidendrum
maduroi can be distinguished from both species by
the wider, 8 mm vs. 4-5 mm, unlobed, widely ovate-
subchordate vs. slightly lobed, narrowly ovate lip
(Ames 1923, Ames & Schweinfurth 1925).

 holotypee, US-677617, not seen; isotype, AMES-
 22677, photo).

DISTRIBUTION: Costa Rica and Panama.

ETYMOLOGY: from the Greek ortho, "erect" and odonto,
"tooth" in reference to the erect tooth at the apex of
the column.

HABITAT: plants of this species were found growing in
montane wet forest at around 2500 m elevation in the
Cordillera de Talamanca.

 Epidendrum orthodontum is similar to E.
 nutantirhachis Ames & C. Schweinf., but it can be
 distinguished by the trilobed lip, the larger flowers
 (sepals 10-12 mm vs. 8-9 mm long; petals 9-10 mm vs.
 6-8 mm long), and the erect mid tooth of the column,
 forming a 90 angle with column (vs. semierect,
 forming a 450 angle with the column) (Hagsater
 1999b).

 DISTRIBUTION: Costa Rica, Colombia and Ecuador. This
 species may well occur in Panama.

 EPONYMY: dedicated to Colonel Paul Scharf, bird
 watcher and occasional orchid collector in Quito,
 Ecuador.

 HABITAT IN COSTA RICA: plants of this species grow
 on both the Atlantic and Pacific watersheds of the
 Talamanca range, in premontane wet forests at
 elevations between 700 to 1200 m.
