416 IRIS FAMILY. 



•>- -t- -I- Perianth parted almost to the base into 6 nearly equal widely spreading divis- 

 ions ; stamens separate or nearly so ; style ii-6-lobed. 



4. NEMASTYLIS. Stem simple or sjparingly branching above, from a corm. Divisions 



of the flower obovate. Filaments awl-shaped, much shorter than the linear anthers. 

 Style short, its 3 lobes parted each into two, bearing long and thread-like diverging 

 stigmas. Pod truncate. Seeds dry, angular. 



5. BELAMCANDA. Foliage and aspect of an Iris with leafy branching stem, from a 



rootstock. Divisions of the flower oblong with a naiTow base. Filaments slender, 

 much longer than the anthers. Style long, club-shaped, its simple branches tipped 

 with a broad and blunt stigma. Pod pear-shaped ; the valves falling away expoM 

 the center covered with black berry -like seeds. 

 « » Spathe l-flowered, the flowers sessile in the spathe (except No. 6.) 

 +- Perianth regular or very nearly so, the stamens equilateral. 



■M- Plant stemless, i.e., the leaves and flowers arising directly from the corm. (Lessons, 



Figs. 105, 106.) 



6. CROCUS. Ovary and pod seldom raised above ground ; perianth with a long and slen- 



der tube ; its oval or roundish divisions alike, or the 3 inner rather smaller, concave, 

 fully spreading only in sunshine. Leaves with revolute margins. 



++ ++ Plants uHth prominent stems. 



— Three branches of the style not divided. 



7. 8CHIZ0STYLIS. Root a scarcely thickened rhizome. Flowers spicate-scattered on 



the side of a simple peduncle, red and showy, the tube slender and somewhat enlarged 

 at the throat, the perianth lobes oblong or ovate and widely spreading. Branches of 

 the style long and subulate. Spathe greenish, lanceolate. 



8. IXIA. Cormous plants, with showy flowers in simple or branched spikes. Perianth 



tube long and slender, the limb ascending or salver-shaped. Branches of the style 

 linear, recurved. Spathe short and membranaceous. 



= = Branches of the style l-divided or -cleft. 



9. FREESIA. Plants of small size, with coated corms and flowers erect in a secund lateral 



short raceme ; perianth tube long and expanding upwards, generally curved, the 

 lobes half-spreading. Spathe as in Ixia. 



*■ +- Perianth generally oblique, curved, or otherwise irregular; stamens mostly uni- 

 lateral. 



++ Flowers in short often secund racemes, or loose panicled spikes. Style branches not 



divided. 



= Inflorescence dense, pilose. 



10. BABIANA. Cormous plants, with flowers of striking colors and usually pilose leaves 



and stem. Flowers in a simple short pilose spike-like cluster or raceme, the tube 

 generally short, erect, the lobes erect-spreading, and clawed or contracted at the 

 base. Small plants, with plaited leaves. 



= = Inflorescence mostly looser, essentially glabrous. 



11. CROCOSMA. Cormous, with a slender stem ending in a lax panicle. Perianth tube 



slender, cylindrical and curved, not dilated at the throat, the lobes spreading in star- 

 like form. Stigmas dilated and denticulate. Leaves sheathing much of the base of 

 the stem. 



12. TRITONIA. Cormous, mostly rather tall. Flowers showy, mostly in loose racemes, 



these either solitary and terminal, or spiked. Perianth with a slender tube either 

 short or long, and which is not prominently dilated above, the lobes nearly equal c 

 oblique and concave or bell-form- spreadiijg. Branches of the style slender, thick- 

 ened or dilated at the apex. Spathe short and membranaceous, often toothed. 



13. SPARAXIS. Cormous, small, nearly simple plants, with few yellow scattered or loosely 



spicate yellow flowers. Perianth tube short, dilated in the throat, the limb some- 

 what unequal, the lobes erect-spreading. Branches of the style slender. Spathe 

 broad and scarious, more or less striate, fimbriate at the apex.
