668. PRIMULA.

 Sp. 1-4. 



B. L. not fleshy, mealy beneath. Margin 

 revolute when young. Sp. 5-7. 



C. L. fleshy, not rugose, convolute when 

 young. 



i. Flowers numerous. Stalks unequal, ex- 

 ceeding involucre. 



a. Throat of Corolla mealy. Sp. 8-14. 



b. Throat not mealy. Sp. 15-17- 



ii. Flowers 2-6. Stalks much shorter 

 than involucre. 



a. Margin of L. entire. Sp. 18-20. 



b. Margin of L. cut. Sp. 21-25. 



A. Rugose, not fleshi/. Margin revolute when 

 young. Calyx imsmatic. Mowers yelloio. 



1. vulgaris. Scapes radical, 1-flowered. 

 L. gTadaally tapering downwards. Teeth of 

 Cal. lanceolato-lineai", acuminate. Border of 

 Cor. flat. p. 3. Woody. 



2. elatior. Scapes ujnbeUate. Teeth of 

 Cal. lanceolate, acuminate. Border of Cor. 

 nearly flat. p. 3, 4. Hedges and tliichets. 

 occ. We have two var. .• — one with tapering 

 L., like tliose of P. vulgaris, which Smith con- 

 siders a var. of that species; and one with the 

 L. alrwptly contracted, like those of P. veris, 

 which seems to me a var. o/" veris. The early 

 L. of P. vulgaris are, however, sometimes ab- 

 ruptly contracted, like those of P. veris, and 

 the later ones of P. veris are sometimes, though 

 rarely, attenuate. P. elatior is between them 

 in this, as in everything else. The mouth of 

 the corolla is in all three sometimes nearly 

 hemispherical, and sometimes cylindrical, 

 forming a sort of second tube. Tlie first flowers 

 of the first var. of 7. elatior are freque?itly so- 

 litary, but smaller and of a darker colour than 

 is usual in P. vidgaris. 



8. veris. Scapes umbellate. L. oblongo- 

 ovate, abruptly contracted and then attenuate, 

 green on both sides. Teeth of Cal. ovate, not 

 acuminate. Border of Cor. concave, p. 4.
