CHELONE/E. II. CHELONE. SIBTHORPIACE^. I. SIBTHORPIA. II. DISANDRA. 



641 



Broad-leaved Chelone. PI. 1 to 2 feet. 



5 C. NEMOROSA (Dougl. in bot. reg. 1211.) branched, gla- 

 brous ; leaves ovate, acuminated, serrated : superior ones stem- 

 clasping, cordate ; peduncles 3-flowered, downy ; calycine seg- 

 ments and bracteas subulate, and are, as well as the corolla, 

 rather downy. If. H. Native of North-west America, in 

 mountain woods, near springs and rivulets. Corolla ventricose, 

 of a rosy purple colour ; anthers woolly. Habit of a species of 

 Pentstemon. 



Grove Chelone. Fl. July, Sept. Clt. 1827. PI. 1 foot. 

 Cult. The species of Chelone are extremely handsome 

 border flowers ; they grow in any common garden soil, but 

 prefer peat, and are readily increased by dividing at the root. 



ORDER CLXXIII. SIBTHORPIA'CE^E (this order contains 

 plants agreeing with Sibthorpia in the characters given below.) 

 D. Don, in edinb. phil. jotirn. vol. 19. no. 37. July, 1835. 

 Scrophularineae genera of authors. 



Calyx 4-8-parted, permanent. Corolla rotate, 4-8-cleft, re- 

 gular, deciduous, imbricate in aestivation. Stamens 4-8, equal, 

 alternating with the lobes of the corolla ; anthers 2-celled ; cells 

 parallel. Style one ; stigma capitate, undivided. Capsule 2- 

 celled, 2-valved, many-seeded ; placenta large, spongy, globose. 

 Seeds erect ; testa membranous ; albumen copious, dense, 

 fleshy. Embryo terete, erect, inclosed. Radicle long, cylindri- 

 cal, obtuse, contrary to the umbilicus, centripetal Herbs, with 



alternate undivided leaves, and axillary, solitary, pedunculate 

 flowers. This small family is intermediate between Scrophula- 

 rmece and Primulacece ; and is distinguished from the first by 

 the regular symmetrical flowers, and globose placenta ; and 

 from the last, in the stamens being alternate with the lobes of 

 the corolla, not opposite them, and in the 2-celled capsule.

 S. PICHINCHE NSIS (H. B. et Kunth, nov. gen. amer. 2. p.

 niform, 7-9-lobed : lobes obtuse; flowers pentandrous. If. F. 

 Native on the burning mount of Pichinca, in rugged places 

 between the plains of Verdecuchu and Chorro de Cantuna, at 

 the altitude of 1800 hexapods. Flowers purple. Seeds very 

 minute. Habit of S. Europce'a. 



Pichincha Sibthorpia. PI. creeping. 



3 S. RETU V SA (H. B. et Kunth, 1. c. p. 391. t. 177.) plant his- 

 pid, creeping ; leaves on long petioles, reniform, many-lobed : 

 lobes retuse; flowers pentandrous. %. F. Native of New- 

 Spain, near Tiangillo, at the altitude of 1500 hexapods. Leaves 

 twice or three times the size of those of S. Europcea. Flowers 

 double the size of those of S. Pichinchensis, purplish violet. 



Retuse-\obed Sibthorpia. PI. creeping. 



Cult. Sibthorpia is a genus of singular plants, but of no 

 beauty ; they are, therefore, only grown in botanic gardens, or 

 those of the curious. They succeed best in peat soil and moist 

 situations, and are readily increased by division. S. Pichinchen- 

 sis and S. retusa require protection from frost in winter. 



II. DISA'NDRA (from l^dis, twice; and avr,p av S P oc, aner
