 in botanic pardons, huwowr, with no thsastrous ri'sults. 

 The drit^i milky jiiiee is very poisonous, and the natives 

 use it with other ingredients (the ipoh poison) for 

 poisoning arrows. The tree grows 1)0-70 ft. high, with 

 alternate distioiious short-std. oblong or olilong-ovate, 

 entire Ivs. and moniveious tis., the sterile lis. in dense 

 heads and the fertile fls. solitary: fr. a l-.seeded fleshy 

 drupe. .\ fiber is yielded irom the inner bark. Another 

 species, A. inn6xia, Bhiine, yields fiber that is used for 

 the making of sacks.

 Showy-flowered climbers, abundant in .southeriunost

The usual .species is .1. leptopus, one of the most con- 

 spicuous and beautiful climbers grown in Florida, and 

 always in flower from early spring to late aiitiiirin. It 

 grows 30 to 40 feet high in good soils. Some plants are 

 shy bloomers, while others are often covered from top 

 to bottom with a mass of bright deej) rosy red. Too 

 much fertilizer effects a verj' vigorous growth at the 

 cost of the flowering. Verandas covered with antigonr)n 

 look extremely beautiful, and cabbage palmettos 

 decorated with rna.sses of its pendent flower-trusses 



form charming objects. The plants form large tubers 

 and when killed down by frost, sprout readily again in 

 spring. Seeds, looking much like buckwheat, are 

 abundantly produced and form a ready means for 

 propagation. Small i)lants from self-sown seeds come 

 up everywhere in l''lorida gartlens. (H. Nehrling.)

 somest summer-blooming greenhouse climbers, requir- 

 ing abundance of light and recommended to be planted 

 near heating-pipes and ^.o be trained on the rafters; 

 usually grown from seeds, but also from cuttings. Give 

 plenty of vv'ater whert in flower but keep dry when at 

 rest. In the S. and the American tropics it is one of 

 the commonest vines on fences, arbors and 

 verandas.

 phulariaces'. Snapdragon. Flower-garden and 

 greenhouse herbs. 



Erect or climbing herbs or even half-shrubs: 

 lvs. usually opposite below and commonly entire, 

 never compound: corolla saccate or gibbous at 

 base, but not spurred, personate or closed at the 

 throat; stamens 4: seeds not winged. — Closely 

 alhed to Linaria, from which it differs in the 

 spurless fls. About 30 or 40 .species in the north- 

 ern hemisphere, particularly in N. Amer. 



Snapdragons are flowered either in the open or 



under glass. The common varieties are forms of 



A. nidjiis, and are perennial, although the first 



crop of bloom is usually the only one that is 



desired. Most of the varieties of this species are 



hardy in the North, if well covered during 



winter. Seeds sown very early in the spring, 



especially under frames, and transplanted, produce 



blooming plants the same season. It is usual, however, 



if early bloom is desired, to sow the seeds in August or 



September, and cover the plants with a mulch on the 



approach of cold weather. These fall-sown plants may 



be transplanted into pots (or grown in them from the 



first) and flowered in the house. For growing under 



glass in this way, snapdragons are very satisfactory. 



The teinperat ure and treatment required for geraniums 



and carnations suit them well. Dwarf varieties are 



used for edgings.
