NICOTIANA 



NIEREMBERGIA 



base, viscid-pubescent: Ivs. thin, half-clasping, some- 

 what auricled, sessile, more or less decurrent, ovate, 

 oblong, elliptic or lanceolate: fls. pedicellate in bracted 

 panicles or racemes; calyx oblong, teeth unequal; 

 corolla woolly without, 2-3 times longer than the calyx; 

 tubes white or whitish; limb drooping, rose-colored or 

 red; lobes acute or acuminate: caps, nearly equaling 

 the calyx. Trop. Amer. Nees Fl. Germ. 24:461. 

 The fls. are diurnal. Cult, from earliest times by the 

 Indians and often runs wild. Its commercial cult, being 

 an agricultural subject is not discussed in this work. 

 It is a striking plant in the garden. Var. angustifdlia, 

 Comes (N. chinensis, Fisch.). This is a narrow-lvd. 

 variety from China and Java of which there are several 

 hybrids. Intro, into the U. S. in 1906. Var. macro- 

 phylla, Schrank. A large-lvd. variety with large red 

 fls., of which there are several horticultural forms, 

 variously listed in the trade as N. grandiflora purpurea, 

 N. atropurpurea grandiflora, N. rubra. 



JV. Bigeldvii, Wats., with sts. 1-2 ft. tall, fls. white 1-2 in. long, 

 is of interest as being the possible origin of N. quadrivalyis and 

 N. multivalvis. Calif. N. trigonoph^Ua, Dunal, has sts. 15 in. tall: 

 Ivs. triangular, sessile, somewhat clasping, 2-2 j^ in. long, J^-J^in. 

 wide: corolla yellowish green, %-%m. long: viscous pubescent 

 throughout. Utah to Mex. and Calif. p T 



NICOTUNIA is a name given by the undersigned to 

 hybrids of Nicotiana and Petunia offered in 1893. They 

 were originally described as follows: "The plants have 

 slender, drooping or trailing tomentose green, red and 

 purple stalks and Ivs. twice or three times as large as 

 the petunia; the fls. are handsome, white, pink, carmine 

 or striped and borne in plenteous profusion. No seed 

 is ever produced, but they are very readily multiplied 

 by cuttings." 



These plants have unfortunately vanished from cult. 

 They were, of course, annuals. They were semi-trail- 

 ing plants, the Ivs. covered with abundant short, 

 woolly hairs. The cross was Petunia hybrida var. 

 grandiflora x Nicotiana wigandioides var. rubra, the 

 former probably being the seed-parent. The singular 

 thing about the cross was the fact that the root seemed 

 in all cases to be paralyzed and very defective, though 

 the tops in all the many hybrids produced grew with 

 much vigor. The blooms were beautiful, and it is a 

 pity that the plants were not grafted on tobacco roots. 

 Subsequently several parties have reported crosses of 

 the tobacco and petunia and also tobacco and sal- 

 piglossis. LUTHER BURBANK. 



NIDULARIUM (from Latin nidus, a nest). Bro- 

 melidcese. Warmhouse epiphytes, requiring the treat- 

 ment of billbergia. 



Flowers perfect, borne in compound heads, the 

 petals joined at the base and not ligulate (in all the 

 typical species) ; anthers attached mostly on the back 

 (in some related plants attached mostly at the base) : 

 Ivs. strap-shaped, ovate or oval, in dense rosettes, the 

 fls. mostly sessile, red, blue, or white; the inner Ivs. of 

 the rosette, here called bract-lvs., are usually highly 

 colored and constitute most of the merit of some 

 species. About 15 Brazilian species, by some referred 

 to Karatas and other genera, but by Mez (DC. Monogr. 

 Phaner. 9) kept distinct. 



During the spring and summer nidulariums will 

 require plenty of heat and moisture, this being their 

 growing season. About the middle of January or when 

 they show signs of becoming more active, they may 

 be placed in a house with a night temperature of 65. 

 Before the plants are started up too much, they should 

 haveany necessary repotting. They do well in either 

 pans, cribs, or wire baskets. The compost should be some 

 light porous material, such as fern fiber, sphagnum 

 moss, or fibrous peat, adding some broken crocks and 

 charcoal for drainage. Gradually increase the tem- 

 perature at night until by summer they are having 75 

 with 10 to 15 higher during the day. Dampen the 



walks and under the benches so as to produce plenty 

 of atmospheric moisture. With the increased tem- 

 perature, do not allow them to become dry at the root, 

 as they like an abundance of moisture. While nidu- 

 lariums like plenty of light, they will need some shade 

 when the sun is powerful, so they will not burn. After 

 flowering they should be encouraged to make new 

 growth. During the winter the temperature may be 

 dropped to about 60 at night and the atmosphere 

 should be kept drier. They will need only a very little 

 water during the dark days of winter, just enough to 

 keep them alive. Nidulariums are increased by suckers 

 like many others of the Bromeliacea3. These may remain 

 on the parent plant until of sufficient size and strength, 

 when they should be taken off and placed in small pots, 

 using the same compost as above. Place these under a 

 frame with bottom heat and a humid atmosphere. In a 

 short time, they begin to make growth, when they may 

 be given the same treatment as the old plants. Sponge 

 often for scale. (J. J. M. Farrell.)

Innocentii, Lem. (Karatas Innocentii, Ant.). Stem- 

 less and stoloniferous: Ivs. about 20, in a dense rosette,

 with many small, spiny teeth, green but more or less 

 tinted brown or red, the oval bract-lvs. bright red: fls.

 1658, a Spanish Jesuit and first professor of natural 

 history at Madrid). Solanacex. CUP-FLOWER. Mostly 

 tender perennial herbs valued chiefly for the open bor- 

 der or for pot-plants; they are mostly of prostrate 

 habit, with showy pale violet or white flowers borne 

 freely through the summer and autumn. 



Stem decumbent or creeping, rarely suberect, dif- 

 fusely branched, the branches usually slender and nearly 

 glabrous: Ivs. alternate, scattered, entire: fls. borne 

 singly on the tips of young shoots, mostly white with a 

 purple center; calyx 5-parted, tubular or bell-shaped; 

 sepals spreading; tube of corolla long, slender, atten- 

 uated below, abruptly expanded above into a broad
