 phenomena in the anthers normal. No contabescence. 



353. N. tabacum, var. fruticosa Hook. fil. U. S. Dept. of Agriculture, 

 1908. Orig. from Portici, Italy. General description given in Comes' 

 Mon. (1899, p. 8) Sp. 1, var. 1. Comes' var. fruticosa not that of Hook, 

 fil., according to Setchell (1912). Inbred for three years, constant 

 for characters noted in crossing experiments. Lovr, shrubby, profusely 

 branched plants, height ave. (1912) from 9 plants, 14* 55+ dem. Lvs. 

 petioled, non-auriculate, leaf count made on main axis from 9 individuals 

 (1912), ave. 12-33 + leaves per plant. Range in variation 10 — 14, but 

 method was very unsatisfactory and results are only approximate. 

 Flowers normal, occasionally 6-sepaled or 6-petaled, 100 flowers examined 

 (1912) were all perfectly normal, slightly darker pink than 300 — 309, 

 deeply lobed corolla, petals acuminate, slender throat and tube. Sepals 

 long, acute, and reflexed at tips. 



373. N. tabacum, var, havanensis, (Lag.) Comes' Mon. (p. 16),

 No. 14, p. 40) U. S. Dept. of Agr. 22164. When first grown, variable 

 in leaf and flower characters. Selected by East for constancy in corolla 

 shape and leaf characters. Race from selfed seed, constant for two 

 years in characters here noted. Hglit. 17*54 — 19*06 dem., ave. 18*3 dem- 

 in 1912. Unbranched main axis, lvs. in number 18 — 21, ave. (1912) 

 19*33 +, auriculate, sessile; inflorescence spreading, flowers dark red, 

 inflated throat, corolla pentagonal, varying toward subrotund lobing, 

 normal as to number of parts, no 6-sepaled or 6-petaled flowers being 

 noted. Fertile. See Comes' Mon. (p. 16) for general description. 



39B. N. tabacum, var. fruticosa hybridae, fruticosa X macrophylla 

 purpurea. Hort. N. calyciflora Caille. Comes' Mon. (p. 10). From 

 Portici, Italy. Same as Nicotiana tabacum var. calycina of Setchell 

 (1912, p. 6) (Fig. 14). Race from inbred seed, constant for two years or 

 more, except in characters noted as otherwise (See Setchell on constancy 

 of this variety). Low, shrubby, profusely branched, 353 -type of plant. 

 Hght. constant in inbred stock, except for the appearance of a single 

 nana plant in 1912. Ave. hght. from 24 (396 — 1) individuals, 

 13*84-1- dem. Lvs. sessile, auriculate, ave. no. per plant 11, with 

 range of 9 — 12 [count includes 24 plants determined from observations 

 on main axis (unsatisfactory)]. Inflorescence normal; flowers reddish 

 pink, subject to splitting of corolla tube and other morphological 

 irregularities. Sepals, petals and stamens fluctuate between 5 and 6
