in unopened buds to Washing'tou in making the cross may have de- 

 teriorated durin«: the two or three days before it could be applied. All 

 of the rosettes of normal color and streug-th were set out and some of 

 a lighter shade of green, a total of 165 plants constituting culture 

 13'35, franciscana X biennis. Of these, -49 rosettes in the group 

 lighter in color failed to develop shoots during the summer but, never- 

 theless, grew into large rosettes which bid fair to survive the winter. 

 I obtained about 90 plants that put forth strong central shoots and 

 numerous side branches from the rosettes; the remainder were less vig- 

 orous in their development. From 381 seeds of the cross biennis X 

 franciscana 167 seedlings were obtained, the seed pans being kept 

 6—7 weeks. The seedlings were all normal in color and similar to 

 one another. From these 150 plants were brought to maturity (1 dwarf 

 excepted), forming the culture 13-36, biennis X franciscana. The char- 

 racters of these reciprocal crosses are as follows: 



13'35. franciscana ■; biennis. 



Cotyledons. About 6 mm. long, broaii at 

 base and short-petioled, similar to biennis. 



Young rosettes. Leaves broadly-elliptical 

 or ovate, short-petioled, resembling fiicjinis. 



Mature rosettes. 4 — 4'.5 dm. broad. Leaves 

 broadly elliptical or spatulate, strongly 

 crinkled. Clear evidence of a blend in 

 the form of the leaves with, however, 

 patroclinous tendencies. Matroclinous in 

 the tendency to send out side branches 

 before the central shoot. 



Mature plants. About 1 m. high. Nume- 

 rous side branches from the rosette in 

 length almost equal to the central shoot, 

 resembling biennis. Stem with a much 

 less heavy pubescence as in biennis, the 

 long hairs arising from red papillae 

 (green in biennis). 



Foliage. Leaves more broadly -elliptical 

 but not so broad or so long as those of 

 biennis. Patroclinous although clearly 

 somewhat of a blend. 



Inflorescence. Bracts '/^ — '/s length of ma- 

 ture buds, relatively broad as in biennis. 



Mature buds. 65 — 7 cm. long. Cone less 

 strongly 4-angled. Sepals tinged with 

 red, varying in its depth of color; sepal 

 tips slender as in bii^nnis. Pubescence of 



13'3(), biennis >( fraticiscnna. 



Cotyledons. 7 — 8 mm. long, broad at base 

 and long-petioled, more like franciscana. 



Young rosettes. Leaves narrow-elliptical, 

 long-petioled, resembling franciscana. 



Mature rosettes. 3-5 — 4 dm. broad. Leaves 

 narrow-elliptical or spatulate, less crinkled 

 or almost plane. More strongly pa- 

 troclinous in the form of the leaves and 

 the lesser degree of their crinkling. 

 Matroclinous in promptly sending up 

 the central shoot. 



Mature plants. About 12 m. high. Nume- 

 rous side branches from the rosette, 

 shorter relative to the length of the 

 central shoot, resembling franciscana. 

 Stem with a pubescence almost as heavy 

 as in franciscana, the long hairs arising 

 from red papillae. 



Foliage. Leaves more uarrowlyelliptical 

 but broader and longer than those of 

 franciscana. Patroclinous although clearly 

 somewhat of a blend. 



Inflorescence. Bracts '/a — V2 b'ugth of ma- 

 ture buds, more narrow as in franciscana. 



Mature buds. 6'.5 — 7 cm. long. Cone 

 strongly 4-augled. Sepals tinged with 

 red varying in its depth of color; sepal 

 tips thick as in franciscana Pubescence
