Corolla noted by Barter " deep orange sometimes red." This species is so like 

 L, elegans that T. Anderson has inscribed Barter, 3381, as L. elegans, T. Anders., 

 though it is typical L. JBarteri. The "bracts" in L. elegans are homologous witli 

 the floral leaves in L. Barteri, and similar to them ; the inflorescence of L. elegans 

 might be theoretically called a linear panicle, the cyme under each floral leaf being 

 reduced to a single flower with 2 bracteoles.

Calyx segments 5, acute, subequal, often aristate. Corolla J-2 in. 

 long, blueish-red, pink, yellow, or white ; segments T), contorted in bud, 

 subequal, more or less in 2 lips ; tube very variable, lower linear-cylin- 

 dric portion from -g^-lj in. long, upper portion inflated. Stamens 4, 

 subsimilar ; anthers 2, pointed or spurred at the base (except in D. 

 Tiiutica and D. nudanthera) ; pollen round or roundish-ellipsoid with 

 several longitudinal ribs. Style hairy ; one stigmatic arm linear-oblong, 

 the other suppressed ; ovary with 2 ovules in each cell. Capsule linear- 

 cylindric, hardly clavate, solid at the base, always perfecting -i seeds. 

 Seeds ovoid, much flattened, densely clothed with white hygroscopic 

 hairs. — Small shrubs. Leaves entire, or obscurely crenate. Flowers 

 mostly axillary, solitary or clustered in small condensed, rarely lax, 

 cymes. Bracteoles 2, less than J the length of the calyx, linear or 

 narrow-oblong. — Calophanes, D. Don; Benth. et Hook. f. Gen. PL ii.
