* Capsule \-celled and l-seeded. 



2. THALIA. Stemless herbs, with an elongated scape and radical long-stalked leaves. 



Corolla tubular, the three exterior divisions similar and equal, the interior ones une- 

 qual (the anterior division broad and hooded, one elongated and clawed and one partly 

 adnate to the stamen and furnished with two bristles on one side). Stigma 2-lipped. 

 * * Ovary S-celled (rarely ^-celled), the cells l-ovuled. 



3. CALATHEA. Strong-growing ornamental-leaved plants with flowers in imbricated 



bracteate heads or cone-like spikes or rarely in somewhat lax spikes. Outer 8 seg- 

 ments of perianth lanceolate, the 8 inner ones irregular and obtuse. Corolla tube often 

 slender. Staminodia present and petal-like. 



* * Capsule 3-celled, the cells several- -seeded. 



4. CANNA. Mostly tall plants with showy flowers in an erect spike or raceme terminating 



the stem. Stamen a petal-like filament with the anther upon one side. 



III. BANANA SUBFAMILY PROPER. Not aromatic or 

 pungent. Stamens 5 with 2-celled anthers, and an abortive 

 naked filament. 



5. MUSA. Strong somewhat palm-like plants with flowers in long nodding bracteate 



spikes or racemes. Calyx tubular and elongated, 3-5-toothed and inclosing the small 

 corolla. Fruit fleshy and indehiscent. 



6. STKELITZIA. One cultivated species, with the scape bearing at apex an oblique or 



horizontal and rigid conduplicate spathe, from which several large and strange-looking 

 blossoms appear in succession ; the 3 outer divisions of the perianth 3'-4' long, orange- 

 yellow, one of them conduplicate and taper-pointed, and somewhat like the two larger 

 of the bright blue inner set, or true petals, which are united and cover the stamens, 

 the other petal inconspicuous.
