Scrophularince— Verbascum. 337 
V. pyramidatum, V. undulatum, and V. acwmindtum are 
other large-growing yellow-flowered species. 
5. CELSIA. 
A small genus of the same habit and inflorescence as the 
last, differing merely in having four didynamous stamens. The 
species inhabit the same regions. Named after Professor Cel- 
sius of Upsal. 
1. C. Crética.—A showy robust biennial growing from 4 
to 6 feet high. Leaves hairy, lyrate-oblong, and the uppermost 
ovate or lanceolate, toothed. Flowers in a leafy spike about 
14 inch in diameter, yellow with two brown spots near the 
centre. The filaments of the shorter stamens bearded; the 
longer stamens and style declinate. A native of Crete, flower- 
ing in Summer. 
Alonséa incisifolia, syn. Célsia urticwfolia, is a tender 
Peruvian perennial having resupinate showy orange-scarlet 
flowers with a dark bloteh. It may be treated as an annual 
for the open ground. 
6. LINARIA. 
A large genus of herbaceous or more rarely frutescent plants. 
Leaves opposite or whorled, the uppermost often alternate. 
Flowers spicate or racemose, or solitary and axillary. This 
genus is remarkable for the personate open or closed corolla 
spurred at the base, with an erect upper lip and trilobate lower 
lip, the middle lobe smallest. Sometimes the corolla is regular, 
with 5 spurs and lobes, and 5 fertile stamens. Fertile stamens 
4, included. Capsule opening by pores. The species are natives 
of Europe, North Africa, and West Asia, and about half a 
dozen occur in this country. Linariwm is the Latin word for 
flax plant, and is applied to this genus in consequence of a 
similarity in the foliage of some species. 
1. L. vulgaris. Toad-flax.—This is one of our handsomest 
native plants, producing its long bracteolate racemes of yellow 
and orange flowers from July to October. It is a glaucous 
erect perennial about 2 to 3 feet high, with linear or lanceolate 
glabrescent leaves. The Peloria, or variety with a regular 
corolla, is more frequently seen in this species than in any other. 
It is constant, and the one usually cultivated, but it is rare in 
the wild state. 
2. L. Dalmdtica.—A tall perennial from 3 to 4 feet high.
