2. Mature Plants.— The mature plants (Fig. 7), 1.5-2 

 in. high, have a more upright habit than biennis. Fre- 

 quently the branching is profuse, the main stem and 

 long side brandies being covered with short shoots. 

 Stems reddish, green only towards their tips, the papil- 

 late glands following the color of the stem. Basal leaves 

 on the main stem ovate or broadly elliptical, about 15 

 em. long (Fig. 8) ; leaves above broadly lanceolate. 



3. Inflorescence.— Bracts early in the season leaf-like 

 and more than half the length of the buds (Fig. 4) ; later 

 becoming very much smaller.
