 lip spreading, 3-lobed. Stamens 4, in pairs, inserted in the tube. Anthers 

 2-celled ; the cells usually pointed or awned. Ovary free, 1 -celled, with 2 

 double or bifid placentas, or 4 distinct placentas, more or less protruding into 

 the cavity, but not united in the axis. Ovules several, usually very numerous.

 incurved tube ; the limb of 5 broad nearly equal lobes, obscurely 2-lipped. 

 Anthers cohering in pairs, 1 -celled, those of the lower lip having the connec- 

 tive produced into a spur at the base, which is the rudiment of the other cell. 

 Placentas of the ovaries much branched, covered with ovules, and nearly fill- 

 ing the cavity. — Parasites, with few or no scales on the short stems. Pedun- 

 cles or scapes long and 1 -flowered.

 acute, varying in length from f to near \\ in. Corolla also variable in size, 

 but usually about \\ in. long, whether the calyx be long or short.
