ferent species introduced ; as yet, however, no remarkable 

 varieties have been obtained ; but there is no doubt, with 

 skilful management, many new and extremely beautiful 

 varieties await the experiments of cultivators. 



ScrophularidcecB. * 



TETRANE>MA, (from tetra, four, and nema, a filament, on account of their being four 

 filaments in this genus,) Bcnth. 

 mexic«innm, Sentli. Mexican Tetranema. A greenhouse plant ; growing a foot high ; 

 with purple and white flowers ; appearing in summer ; a native of Alexico ; increased by 

 division of the root; grown in leaf mould and sandy loam. Bot. Reg. t. 52, 1843. 



Syn ; Pentstfemon mexic^nus Hort. 



Under the name of Pentstemon mexicanum, this plant 

 has been received from Belgium, where it was introduced 

 from Mexico. But Mr. Bentham, who has given particu- 

 lar attention to this class of plants, is of opinion that this 

 is certainly a new genus, very near Pentstemon, with the 

 same calyx and corolla, but without any trace (or very lit- 

 tle) of the sterile stamen, so conspicuous in Pemtstemon. 

 It is a greenhouse plant, growing eight to twelve inches 

 high, with an almost stemless habit, and with a "profusion 

 of little corymbs of showy purple and white flowers, which 

 rise up from among the leaves on long purple scapes." It 

 should be kept rather dry in winter, and in spring repotted 

 in a light free soil, chiefly leaf mould and sandy loam, and 

 placed in the greenhouse, where it will flower all summer. 

 It is propagated from seeds or cuttings. Probably in our 

 less humid climate it might be managed as a frame plant, 

 and turned out into a dry border in summer. It is a very 

 pretty plant. {Bot. Reg., Oct.) 



VERO'S^lCA. 



Fpccio^a Paxt. Showy Speedwell. A greenhouse plant ; growing from twelve to eighteen 

 inchfs lii^jh : willi blue flowers ; appearing all summer ; a native of New Zealand ; increas- 

 ed by cuttings ; grown in light open compost. Pax. Mag. Bot. Vol. X. p. 247. 



A very showy and beautiful species of the Veronica, 

 brought from New Zealand in 1841, Its general aspect is 

 that of Lisianthus Russelha;??/5, but it is a robust growing, 

 decidedly evergreen shrub, with an abundance of neat foli- 

 age, and an extraordinary^ number, as well as succession, 

 of flower spikes, about three inches in length, densely 

 clothed with deep blue blossoms. These flower spikes ap- 

 pear singly at the axil of every leaf, and as the blossoms 

 fade ofl" from blue to Avhite, they give a pretty A^ariety to 

 the ptaut. Add to this that its habit is particularly clean
