zine and the description that tells little of value for the 

 problem under consideration. 



The following- is a description of this sheet in the Gray 

 Herbarium : 



1. Stems and Foliage. — The stem bears long hairs 

 arising from papilla' (glands) which are colored red as 

 in Lamarckiana and are about as numerous as in that 

 species. A detached leaf (Fig. 15, a), about 18.5 cm. long 

 with sinuate margins, slightly lobed below, and with some 

 evidence of former crinkles, suggests by its shape (al- 

 though too small) the basal leaves of Lamarckiana. The 

 upper foliage is similar to a broad-leaved type of grandi- 

 flora, the leaves being short-petioled and not so nearly 

 sessile as in Lamarckiana. 



2. Inflorescence. — The inflorescence has longer inter- 

 nodes than in Lamarckiana and consequently is not so 

 compact; in this respect it resembles grandiflora. The 

 bracts are broad at the base, slightly toothed, and per- 

 sistent, becoming lanceolate leaves on the fruiting 

 branches as in grandiflora. 



3. Buds.— The buds (Fig. 15, b) are about 9.5 cm. long, 

 not stout and 4-angled as in Lamarckiana, but with a cone 

 circular in section as in grandiflora. Sepals apparently 

 green, their tips attenuate as in grandiflora and project- 

 ing 1 cm. beyond the folded petals; pubescent, with long 

 hairs arising from papillae among much shorter sessile 

 hairs as in Lamarckiana. 



4. Flowers.— The flowers are som< 

 those of any grandiflora known to mc 

 cm. long, as long as those of the larj 



mm. above the tips of the anthers, in tli 

 ing with both Lamarckiana and grandi 



o those of grandiflora; 

 psules of Lamarckiana.
