E.ramosum var. lanceolatum Griseb. has broader 
leaves and larger bracts and flowers. As interpreted by 
Cogniaux, the variety danceolatum seems to have 2-flow- 
ered inflorescences. In our judgment, this is the West 
Indian representative of Schlechter’s 27. modestiflorum. 
E..modestiflorum Schitr. of which the type was col- 
lected by A. M. Brenes no. 128 in August 1921 at San 
Pedro de San Ramon, Costa Rica, differs in its stiffer 
and stouter habit, usually 2-flowered inflorescence and 
broader thicker leaves. Its habit is also more dwarf and 
often less branched. 
E. Boissierianum Schltr. (a new name for £2. biflorum 
Cogn., which is a homonym) is a plant much like /. mo- 
destiflorum in habit, but approaches H.imbricatum Lindl. 
in some of its characteristics. The type was collected in 
Costa Rica by Ad. Tonduz. 
E.santaclarense Ames, of which the type is C. H. 
Lankester & A. Sancho no. 448, collected at Santa Clara 
south of Cartago, Costa Rica, is a robust branched plant 
with lax inflorescences, with the flowers somewhat simi- 
lar to those of £7. modestiflorum and with the bracts of 
the inflorescence also suggesting those of J”. modestiflo- 
rum, but more elongated. It seems strictly intermediate 
between the two forms 1. modestiflorum and E.imbrica- 
tum. 
E.imbricatum Lindl. of which the type was collected 
by Prescott in Brazil and which is also represented by 
Gardner no. 680 from the Organ Mts., Brazil, typically 
has a head-like inflorescence ‘‘two inches long, by one 
and a half inch broad.”’ (fide Lindley, Fol. Orch. Epid. 
p. 78). The bracts of the inflorescence are carinate, con- 
duplicate and large in the extreme form (cf. diagram on 
p. 42), but vary toward those of the £. modestiflorum 
form. The inflorescence also is often less head-like, more 
open and fewer-flowered than in the plants described by 
[ 44 ]
