ally not much stouter than the 2. modestiflorum variant 
of the typical form or only slightly branched (J. Bois- 
sierianum), up to 2m. tall (fide Cogniaux in Mart. F'l. 
Bras. 8, pt. 5 (1898) 170). Stems erect or possibly more 
or less recumbent (rooted when recumbent), stout, com- 
monly 5-6 mm. in diameter just below the inflorescence. 
Leat-sheaths finely maculate in the extreme develop- 
ment. Leaves rather coriaceous, ligulate to oblong-lan- 
ceolate or rarely elliptic, 2.5-14.5 em. long, 8-25 mm. 
broad (the main leaves commonly 15 mm. or more broad), 
apex entire or unequally bilobed. Inflorescence terminal, 
variable from 1- to 2-flowered (J1. Boissiertanum) to sev- 
eral-flowered. When it is several-flowered it is open (J!. 
santaclarense) to head-like (4.imbricatum). Bracts of the 
inflorescence (or spathes in 27. Boissierianum) apt to be 
finely maculate (always so in the I”. santaclarense and 
E..imbricatum forms), 1.5-8 em. long, usually imbricated 
(well separated in the H.santaclarense form which was 
described from mature plants), apex rounded to subacute, 
often apiculate, rather strongly conduplicate and carinate 
or (in the /7.santaclarense form) rounded and ecarinate 
on the back, elliptic-oval to broad-ovate when spread out. 
Flowers rather coriaceous, approximate to 7-10 mm. 
apart in the #7. santaclarense form. Pedicel and ovary up 
to 83cm. long (7. santaclarense form). Lateral sepals va- 
riable in shape, lanceolate, oblong-lanceolate or ovate- 
lanceolate, somewhat oblique, 9 15 mm. long, 8-5 mm. 
wide, acute to acuminate, slightly carinate on the dorsal 
surtace toward the apex. Dorsal sepal lanceolate, oblong- 
lanceolate or elliptic-lanceolate, 9-15 mm. long, 8-5.5 
mm. wide, obtuse (rarely) to acute, slightly carinate on 
the dorsal surface near the apex. Petals very variable in 
shape, from linear to spatulate-elliptic, but commonly 
tending toward narrowly elliptic-lanceolate, 8.5-14.5 
mm. long, 1.8-5.6 mm. wide, apex varying from obtuse
