3. C. Wisteriana. Conrad. WISTER’s CoraL-root. Stem 8 to 16 in. 
high, not as slender as No. 2. Flower spike with 6 to 18 drooping 
flowers, each about 4 in. long with slender flower stalks 1/6 as long as 
the flowers. Petals and sepals about equal. Lip longer than petals, 
broadly oval with very slight indentation at apex and with purplish 
dots on the upper surface. Woods. Feby.-May. 
4. C. maculata, Raf. Larce Corat-root. (C. multiflora, Butt.). 
Stem 8 to 20 in. high; flower spike 2 to 8 in. long with from 10 to 30 
nearly erect brownish-purple flowers. Petals and sepals unequal. Lip 
much shorter than the lateral sepals, broad, almost quadri-lateral with

flower spike 2 to 6 in. long. Flowers larger than either of the pre- 
ceding species, purple. Petals, sepals and lip about the same length. 
Spur none. Lip oval without lobes or notches, narrowed at the base. 
14. TIPULARIA, Nutt. 
Herb. arising from a large solid bulb, with a single broad leaf on a 
slender stalk which arises, in autumn, directly from the bulb. Leaf 
purplish beneath; the flower scape, arising also from the bulb, appears 
in the following summer, bearing a number of small greenish flowers. 
Sepals and petals nearly alike, but the latter narrow; lip slightly longer 
and with 3 lobes. Spur about 3 times as long as the flower and very 
slender. 
T. discolor, (Pursh.) Nutt. Crane-rry Orcnts. (7. wunifolia, 
(Muhl.) BSP. Flower stem 15 to 20 in. high. Flower spike 5 to 10 
in. long. Flowers green, tinged with purple. In woods. July-Aug. 
15. CALOPOGON, R. Br. (Limodorum, L.) 
Herb arising from a bulb with a long grass-like leaf and a naked 
flower scape on which are from 3 to 15 showy flowers. The ovary 
(which is in these orchidaceous plants the flower stalk), does not twist 
and the lip is therefore on the upper or inner side of the flower. It is 
conspicuously bearded on its upper side.
