354 BIGNONIACEAE. 



the caljx curved and longitudinally split, was also represented at the Agri- 

 cultural Station in 1914 by a vigorous young tree, and by a tall tree in 

 A^'ictoria' Park. 



Seedling plants of a species of Jacaranda, presumably South American, 

 were seen at the Agricultural Station in 1914. This genus consists of shrubs 

 and trees with pinnate or bipinnate leaves and terminal panicles of mostly 

 blue flowers. 



Family 12. GESNERIACEAE Lindl. 



Gesxeria Family. 



Herbs or shrubs with opposite, often unequal leaves, and variously 

 clustered or solitary, often showy, perfect irregular flow^ers. Calyx mostly 

 inferior, gamosepalous. Corolla gamopetalous, the limb usually oblique 

 and more or less 2-lipped. Stamens 4, or sometimes 2, borne on the corolla- 

 tube. Ovary 1-celled, or imperfectly 2-celled; ovules numerous, minute, 

 anatropous, on parietal placentae. Fruit mostly capsular, many-seeded. 

 About 90 genera and over 1000 species, of tropical and subtropical distribu- 

 tion. There are no native nor naturalized species of this family in Bermuda. 



Isoloma Tydaea Bailey, Monkey-flower, Colombian, a glandular-villous 

 herbaceous species l°-2° high, with petioled ovate often cordate, serrate 

 more or less mottled leaves 2'-4' long, the axillary flowers long-peduncled, the 

 calyx 4"-5"' long, with 5 triangular lobes, the irregular corolla about IV long, 

 red and yellow, its lobes spotted, is grown in flower-gardens. [Achimenes picta 

 Benth.] 



Lefroy records the occurrence of a species of Gloxinia in gardens. 



Family 13. ACANTHACEAE J. St. Hil. 



Acanthus Family. 



Herbs, or some tropical genera shrubs or small trees, with opposite 

 simple estipulate leaves, and iiTegular or nearly regular perfect flowers. 

 Calyx inferior, persistent, 4— 5-parted or 4-5-cleft, the sepals or segments 

 imbricated. Corolla gamopetalous, nearly regularly 5-lobed, or 2-lipped. 

 Anther-bearing stamens 4, didynamous, or 2 only; anther-sacs longitu- 

 dinally dehiscent. Disk annular, or cup-like. Ovary 2-celled; ovules 2-10 

 in each cavity, anatropous or amphitropous; style filiform, simple; stigmas 

 1 or 2. Capsule dry, 2-celled, loculicidally elastically 2-valved. Seeds not 

 winged, borne on curved projections (retinacula) from the placentae, the 

 testa close, mostly roughened, often developing spiral threads and mucilage 

 when wetted. Endospeim in the following genera none; cotj^edons flat, 

 commonly cordate. About 175 genera and 2000 species, natives of tem- 

 perate and tropical regions. 



1. JUSTICIA [Houst.] L. 

 Herbs, or shrubs, with entire leaves, the flowers variously clustered. 

 Calyx deeply cleft, its segments narrow, nearly equal. Corolla-tube mostly 

 shorter than the 2-lipped limb, the upper lip 2-cleft, the lower 3-cleft. Stamens 

 2, borne in the throat of the corolla; anthers 2-celled; staminodes none; lower 

 anther-sac minutely appendaged. Style filiform; ovules 2 in each ovary-cavity. 

 Capsule oblong. [In honor of James Justice, a Scotch gardener.] Over 100 

 species, of tropical distribution. Type species: Justicia Adhatoda L.
