THE FLORA OE THE NOBTHBBN TERRITORY. 181 



Stj'le-branches the same number as ovary-cells. Mature carpels separating 

 more or less from the axis (imperfectly so ia some Abutila). 



Ovules solitary ia each cell, ascending with a ventral raphe. — 2, Mal- 

 vastrum. 



Ovules solitary in each cell, pendulous or horizontal with a dorsal raphe.

Styles with decurrent stigmas. Flowers more or less dioecious. — 3. 



Plagianthus. 

 Stigmas terminal, capitate, or truncate. — i. Sida. 

 Ovules 2 or more in each cell. Bracteoles none.' Stigmas terminal. — 

 1 . Abutilon. 



Tribe II. Hibiscece. — Staminal column truncate or o-toothed at the 

 summit, bearing the anthers or filaments on the outside, or rarefy at the summit 

 also. Style-branches or stigmas the same number as ovary-cells. Carpels 

 united in a several-celled capsule, locuhcidal or indehiscent. 



Style branched at the top or with radiating stigmas. Ovary 5-celIed. — 

 5. Hibiscus. 



Style undivided, with decurrent stigmas. 



Bracteoles 3 to 5, narrow, not cordate, sometimes very small. 



Ovary 3, 4 or rarely o-ceUed. Capsule coriaceous, locuhcidal. — 



7. Cienfuegosia. 

 Ovar3^ .5-celled. Capsule woody, sometimes indehiscent.— 

 6. Thespesia. 

 Bracteoles 3, broad, cordate. — 8. Gossypium. 



I. ABUTILON, TouRN. 1763. 



( Abutilaea, F. v. 31., 1852 ; Beloere, Shuttl, 1862 ; Bogenhardea, Reichb., 

 1841; Herissantia, Medic, 1789; Lass, Adans., 1763; Prestonia, Scop., 

 nil. Fleischeria. Lantern-Flower. Chinese Lantern. All yield good fibre. 

 I. Capsule truncate or concave at the top. Carpels (usually 2 or 3- 

 seeded), angular-pointed or awned at the upper outer edge, persistent, or rarely 

 at length deciduous, leaving the filiform placenta attached to the axis. 



Carpels (usually 10 or fewer), not exceeding the calyx-lobes, the points 

 erect, or rarely divergent. Stems usually (perhaps always) shrubby. 

 Calyx-lobes shorter than the tube. 



Calyx 1 in. long, campanulate, lobes acute, nearly as long as 



the tube. Petals twice as long. — 1. A. amplum. 

 Calyx I to J-in., lobes acuminate or rather obtuse, spreading, 

 much shorter than the tube. — 7. A. leucopetalum. 

 Calyx-lobes longer than the tube or cup, acuminate. — 8. A. oto- 

 carpum. 

 Carpels usually exceeding the calyx-lobes, the points often divergent. 

 Herbs usually tall, sometimes hard, almost woody at the base. 

 Stems coarse and erect. Leaves broadly cordate. 



Stipules small and subulate. Flowers mostly axillary. — 6. A. 



indicum. 

 Stipules broadly semisagittate. Flowers in terminal leaflets 

 racemes or panicles. — 2. A. auritum. 

 Stems rather slender. Leaves ovate or cordate-lanceolate. Capsule 

 truncate, with short divergent points. — 9. A. oxycarpum. 



II. Carpels (often 1 -seeded by abortion) rounded or angled at the top, 

 quite distinct, and seceding from the axis when fully ripe.
