626 ORCHIDACEZ CALYPSO 
- CORALLORHIZA 
2 teh 1 CALYPSO Salisb. Par, Lond, t. 89. 
Low herbs with a single bracted scape-like stem, solitary green 
radical leaf and a large terminal showy flower. Smaller lobes of 
the perianth similar and nearly equal : the lip comparatively large, 
saccate, with 2 short spurs below the apex, becoming inferior hy the 
pedicel curving backward. Column erect broadly winged and petal- 
oid, oval and concave, bearing the hemispherical anther on the 
summit. Pollen masses in 2 pairs, the lower smaller, compressed, 
sessile upon a nearly square membranaceous gland. 
C. borealis Salisb. |. c. Stem 3-8 inches high with 2 or 3 membrana- 
ceous brownish-green sheaths and a linear bract at the summit, leaf broadly — 
ovate or slightly cordate, 1-2 inches long, petioled: flowers drooping, pedi- 
celled: sepals and petals lanceolate, acuminate, light rose-color, 6-9 lines 
long lip usually slightly longer, inflated saccate, brownish-pink mottled 
purple, the edge margined at the apex and bifid or entire nearly equalling 
the tooth-like spurs and with a tuft of (in ours white) hairs at base: 
column half the length of the petals: capsule oblong-cylindric, an inch long, 
about equalling the slender pedicel. \In damp open forests California to 
Alaska and the Atlantic States: also in Europe. ) 
2 CORALLORHIZA R. Br. Ait. Hort. Kew. ed. 2, v, 209 
Scapose perennial herbs without green leaves from coral-like 
branched roots, the leaves al] reduced to sheathing scales, and more 
or less showy flowers in terminal racemes. Sepals and petals as- 
cending, the upper somewhat incurved, similar and nearly equal, 
but the lateral sepals oblique at base and either decurrent in a 
short spur adnate to the side of the ovary, or forming a projecting 
gibbosity above it: lip dilated and more or less recurved, flat or 
concaye, witha pair of somewhat prominent longitudinal ridges 
near the base. Column semiterete and narrowly margined, 
broader at base, somewhat incurved, bearing the caducous anther 
onthe summit. Pollen-masses in 2 pairs, distinct, sessile upon a 
short oblong gland. Capsules reflexed. 
* Spur present: flowers small, yellowish-green or whitish. often 
tinged or mottled with purple. 
+ Spur more or less prominent: sepals and petals 3-nerved: 
capsule oblong-cylindric. 
C. multiflora Nutt. Journ. Acad. Philad. iii, 138, t. 7. Stems 8-20 
inches high, purplish, clothed with several appressed scales: racemes 2-8 
inches long, 10-30-flowered : flowers 6-9 lines high, brownish-purple, short- 
peduncled: petals and sepals somewhat connivent at base, linear-lanceo- 
late, about 3 lines long: lip white spotted and lined with purple, oval or 
ovate in outline, deeply 3-lobed, crenulate, the middle lobe broader than 
the lateral ones, its apex curved, spur manifest, but wholly adnate to the 
ovary: column stout % the length of the petals, the margins broader and 
somewhat thicker at base: capsule ovoid or oblong, 6-9 lines long, narrowed 
to a stout rather long pedicel. Rather common in open forests at low and 
middle elevations, Brit. Columbia to California and the Atlantic States. 
C. Mertensiana Bong. Veg. Sitch. 165. Stems 6-20 inches high, dark 
red or purple, many-flowered : sepals and petals linear-lanceolate, 3-4 lines 
long, dark red: spur a line long, the lower half free from the ovary: rip
