of Ipswich, England, a seedsman who probably obtained from 

 Carter and Company their novelty. It is then possible that the 

 plant grown by Dr. Gray was not more than one or two generations 

 removed from the original cultures of Carter and Company. The 

 following is a description of the sheet in the Gray Herbarium 

 illustrated by Fig. 1 : — 



1. Stems and Foliage.^^The stem bears long hairs arising from 

 papillae which are colored red as in Lamarckiana and are about as 

 numerous as in that species. The large detached leaf, about 

 18-5 cm. long with sinuate margins, slightly lobed below, and with 

 some evidence of former crinkles, suggests by its shape (although 

 too small) the basal leaves oi Lamarckiana. The leaves of the upper 

 foliage, short petioled, are not so nearly' sessile as those of 

 Lamarckiana. 



2. Inflorescence. — The inflorescence has longer internodes than 

 in Lamarckiana and consequently is not so compact. The bracts 

 are broad at the base, slightly toothed, and persistent, becoming 

 large, lanceolate leaves on the fruiting branches : those oiLamackiajia 

 remain much smaller. 



3. Buds, — The buds are about 9-5 cm. long, not stout and 

 4-angled as in Lamarckiana. The sepal tips are more attenuate 

 than in Lamarckiana, projecting 1 cm. beyond the folded petals. 

 The pubescence upon the sepals consists of long hairs arising from 

 papillae among much shorter hairs as in Lamarckiana. 



4. Flowers. — The petals are about 4-5 cm. long, as long as 

 those of the largest forms of Lamarckiana. The stigma lobes are 

 about 8 mm. long, and close to 5 mm. above the tips of the anthers, 

 in these respects agreeing with large-flowered forms oi Lamarckiana. 



5. Capsules. — The capsules, about 3 cm. long, are longer than 

 those of Lamarckiana and not so stout. 



From the above it will be noted that the plant grown by 

 Dr. Gray differed from the Lamarckiana of the cultures of De Vries 

 in the longer internodes of the inflorescence, in the larger more 

 leaf-like bracts, in the more slender form of the buds, in the more 

 attenuated sepal tips, and in the longer seed capsules. It would 

 profit little to discuss at present whether or not this plant was truly 

 representative of the cultures of Carter and Company and whether 

 or not their plants became greatly modified during the quarter 

 century before the time when De Vries began his studies, at about 

 1886, and isolated the form that we know to-day as CEnothera 

 Lamarckiana De Vries,
