Scrophularinece Verbascvm. 337 



F. pyramidatum, F. undulatum, and F. acuminatum 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. Cr&tica. A s'howy 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 

 1J 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. 



Alonsba incisifdlia, syn. Celsia urticcefdlia, is a tender 

 Peruvian perennial having resupinate showy orange-scarlet 

 flowers with a dark blotch. It may be treated as an annual 

 for the open ground. 



6. LINABIA. 



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. Linarium 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. Dalmatica. A tall perennial from 3 to 4 feet high.
