PASSIFLORACEAE. 253 



Passiflora malifomiis L., Water Lemon, of tropical America, mentioned 



by Lefroy as fountl in gardens, is a high-climbing, glabrous vine, with ovate 

 thin entire acuminate leaves 3'-6' long, the slender petioles bearing 2 round 

 nearly flat glands; its large variegated flowers are subtended by 3 pointed 

 membranous whitish bracts about 1' long; the globose fruit is about IV hi 

 diameter. 



Passiflora quadrangularis L., Graxadilla, tropical American, a long 

 glabrous vine with sharply 4-angled stems, broadly ovate, entire petioled 

 short-acuminate leaves 3-6' long, the petioles bearing 2 or 3 pairs of small 

 sessile glands, the large ovate stipules membranous and acute, the axillary, 

 involucrate flowers 3'-5' broad with rose-colored petals and violet crown, the 

 berry about A' thick, has been planted for ornament. 



Passiflora edulis Sims, Water Lemon, Brazilian, a vine with 3-lobed 

 leaves, 3'-5' broad, the lobes acute and irregularly serrate, the petioles with 

 2 glands at the apex, the axillary flowers purplish, l^'-2' broad, involucrate by 

 2 small glandular-serrate bracts, the fruit a purple oblong edible berry, about 

 2J' long, is frequently planted and fruits abundantly. 



Passiflora princeps Todd., a species with, showy crimson flowers in long 

 racemes, and deeply lobed leaves, was grown by Lefroy in a greenhouse at Mt. 

 Langton, prior to 1877, and flowered profusely. 



Passiflora stipulata Aubl., South American, is a long glabrous vine with 

 angled stems, deeply 3-lobed leaves 3'-5' broad, subcordate at the base, the 

 foliaceous, subulate-tipped stipules V long or more, the petiole with 1 or 2 

 sessile glands; the showy flowers are 3'-4' broad, with rose-purple petals, the 

 crown violet above, purple below, with 3 bands of white spots, the stamens 

 orange. This vine is occasionally planted for ornament; its reference to P. 

 stipulata Aubl. is not wholly satisfactory. 



Another Passion-flower, a slender vine with deeply 5-parted leaves, their 

 segments linear, 2'-3' long, the slender petiole bearing 2 small, sessile glands 

 at the middle, seen without flowers at Paget Eectory in 1914. has not been 

 determined specifically. 



Lefroy records failure in growing two species of Tacsonia at Mt. Langton. 



Order 24. BEGONIALES. 



Herbs, mostly succulent, some slightly woody, a few species climbing. 

 Leaves alternate, entire, toothed or lobed, inequilateral; stipules 2, distinct, 

 usually caducous. Flowers cymose, monoecious, asymmetric, cymose on 

 axillary peduncles, bracted, mostly white or rose. Staminate flowers usually 

 with 2 opposite sepals, the petals, when present, imbricated; stamens 

 numerous, the anthers continuous with the filaments; ovary rudimentary or 

 wanting. Pistillate flowers usually with 2-5 perianth-segrments and without 

 stamens; ovary commonly 3-celled; styles 2-5, commonly 2-cleft; ovules 

 very numerous, anatropous. Fruit capsular, dehiscent, or rarely baccate. 

 Seeds many, minute, reticulated, with little endosperm or none. Only one 

 family.
