1. Tipularia unifdlia (Muhl.) B.S.P. Foliage glabrous. Leaf solitary, devel- 
oping in the fall and lasting till spring ; blade ovate or ovate-lanceolate, 4-9 cm. long, 
acute or acuminate, truncate or subcordate at the base, plaited, brown-spotted : scape erect, 
3-6 dm. tall, simple: raceme 4 as long as the rest of the scape or shorter: bracts none: 
pedicels spreading: sepals linear or oblong-linear, 6-8 mm. long, rather obtuse : lip as 
long as the petals or shorter, 3-lobed, the middle lobe narrow: spur slender, thrice or 
four times as long as the petals: column shorter than the petals, often minutely pubescent 
at the top: capsules oblong, 10-12 mm. long. [T. discolor Nutt.] 
In woods or on banks, Vermont to Michigan, Florida and Louisiana. Summer. 
30. DENDROPHYLAX Reichenb. f. 
Epiphytic herbs, with dense clusters of roots. Leaves wanting or obsolete. Scape 
simple, slender. Flowers solitary at the top of the scape or few in a terminal raceme. 
Perianth often white. Sepals 3, nearly equal, spreading. Lateral petals nearly like the 
sepals. Lip erect, sessile, 3-lobed, the middle lobe 3-lobed, the lateral lobes angular, each 
prolonged at the base into a filiform spur. Column very short. Anthers 2-celled, ter- 
minal, lid-like, incumbent. Pollen-masses 2, waxy, unappendaged. Capsule beakless. 
1. Dendrophylax Lindénii Benth.  Epiphytic, with fleshy, cord-like roots 1-4 dm.

sepals linear or linear-lanceolate, 2.5-5 cm. long: lateral petals similar to the sepals: lip 
ample, 3-5 cm. long, the middle lobe with 2 linear-lanceolate attenuate spreading segments 
5-10 em. long: spur filiform, 10-15 cm. long: capsule oval or oblong-oval, stalked. 
On palms, southern peninsular Florida. Also in Cuba. 
31. EPIDENDRUM L. 
Epiphytic herbs, clinging to the bark of trees. Leaves persistent. Flowering stems 
simple or branched, each terminated by a raceme or panicle. Sepals and lateral petals 
quite similar, and equal, mostly spreading. Lip dilated above: claw wholly or partially 
adnate to the column : blade entire or parted : spur none, or adnate to the ovary. Anther 
lid-like. Pollen-masses 4, stalked. Capsule somewhat elongated, ribbed. TREE ORCHIS. 
Flowering stems with one or several remote scales above the leaves. 
Lip 3-lobed : sepals and lateral petals obtuse or abruptly pointed.
