C. hirsutum Mill. Gard. Diet. Ed. 8:3. 1768. 



A stout perennial, prominently leafy, which is found from 

 two and one-half to three dm. high and has stout cylindrical 

 rhizomes. The stem, which is seventeen cm. high, is large, 

 pubescent, noticeably setulose at the nodes and slightly six- 

 angled. There are usually five, broadly ovate, acuminate 

 leaves, one- half as wide as long and frequently measuring elev- 

 en cm. in length and having seven or nine conspicuous nerves. 

 The peduncle is six or seven cm. high, glandular, glaucous, 

 with a slight torsion. The ovate bract is twice as long as wide. 

 The flower is large, showy and somewhat coarse in texture. 

 The sepals are long lanceolate, greenish brown, veined and 

 spotted, the inferior sepals being imperfectly united while the 

 upper sepal is slightly inclined. The lateral petals are linear, 

 lanceolate, wavy, colored like the sepals, not glossy and some- 

 what longer than the third petal. The labellam is inflated, 

 very convex above while the pale, dull yellow surface is slight- 

 ly roughened. The oblong lanceolate staminodium is two cm. 

 long, yellow, flecked with ferruginous macules and is declined. 

 The column is declined, while the thick, leathery, stigmatic
