propagated to a considerable extent by separating the 

 prostrate, rooting branches and potting them. This 

 method was soon abandoned in favor of propagation by 

 cuttinirs. Verbenas root very readily and they were 

 grown from cuttings almost exclusively up to 1880, ex- 

 hat seed propagation was employed for the pro- 

 duction of now varieties. During all this pe- 

 riod, as a consequence of much fortuitous and 

 intentional hybridizing, and of no effort hav- 

 ing been made to tix varieties, seedlings were 

 very variable and untrue to parent varieties. 

 Soon after th'e decline of the Verbena in 1868- 

 TH seed propagation was more extensively 

 employed. It obviated the very troublesome 

 experience of wintering over stock plants, 

 which were so susceptible to attacks of mildew 

 and aphis. Soon efforts were made to fix 

 strains that would come true to color and habit 

 from seed. This has been most successfully 

 accomplished, and the Verbena is gaining 

 much of its popularity through treatment as an 

 annual. Seeds are sown in March. The plants 

 are hardened off in a coldframe and set out in 

 the latter part of May. They flower profusely 

 from June to October. Striped varieties are 

 not easily fixed.

 ( I'. hybrida). lt is impossible to satisfac- 

 torily classify the hybrid garden Verbenas. ac- 

 cording to their botanical derivation. They 

 are conveniently classed according to color of 

 flowers into: (1) Selfs, or one-colored varieties; 

 C2) Oculatas. or eyed varieties; and C<) Ital- 

 ians, or striped varieties. As to habit they may 

 be divided into: (1 ) Standards, those of the 

 ordinary loose, spreading growth; and (2) 

 Compactas, which are much reduced in stature 

 and of more condensed form. Verbenas now 

 in cult, are shown in Figs. 2652-4.

rather distinct forms: var. Melindre has oblong to ob- 

 long-lanceolate Ivs., which are unequally incised-serrate. 

 This form is less hirsute and is more graceful and vig- 

 orous. It was the form first introduced to cultivation. 

 Var melindroides has shorter, broader Iv-. and is more 

 hairy. Different forms occur over southern Brazil, 

 Uruguay, Paraguay, and the whole of the Pampas.
