ALONSOA I Alonzo Zanoni, Spanish botanist) . Scroph- 

 ularidcece. Trop. Amer. plants, cult, as annuals in the 

 open, or rarely grown in pots. They are tender, and need 

 protection from frost. Seeds are usually started under 

 glass in the N., although plants bloom well from seeds 

 sown directly in the open. Use only finely prepared soil. 

 Fls. showy; plant of good habit. The corolla is 'very 

 irregular and turned upside down by the twisting of the 

 pedicel, bringing the larger lobe uppermost: stamens 4: 

 Ivs. (at least below) opposite or in 3's. Cult, species 

 mostly from Peru and Mex. 



incisifolia, Ruiz & Pav. (A. urticcefolia, Hort. Celsia 

 urticcefdlia, Sims, B.M. 417). About 2 ft. high, erect: 

 Ivs. ovate to oval-lanceolate, long-stalked, deeply cut- 

 toothed: fls. nearly Kin. across, very irregular (some- 

 what hood-shaped), scarlet, with protruding organs, on 

 slender axillary peduncles. Also a white-fld. var. An- 

 nual; but perennial in warm countries or under glass. 



Var. Warscewiczii, Boiss. (A. Warscewlczii, Regel. 

 A. grandiflbra, Hort.). Fls. larger (often 1 in. across), 

 rose-red, the plant more herbaceous and more perfectly 

 annual. Also white-fld. The commonest form in our 

 gardens. 



myrtifdlia, Roezl. Plant 2-3 ft. : Ivs. broad-lanceolate, 

 canaliculate, prominently serrate: fls. large, scarlet (a 

 white var. ) . Perennial under glass. Useful for winter- 

 growing in pots. 



linifdlia, Roezl. Plant l^ft. or less high: Ivs. lanceo- 

 late or narrower, entire: fls. bright scarlet. 



A . acutifblia, Ruiz & Pav. Lvs. less cut than in A. incisifolia : 

 scarlet. A. caulialdta, Ruiz & Pav. Lvs. less cut than in incisi- 



folia : fls. smaller: st. 4-angled. A. linearis, Ruiz & Pav. Lvs. 

 linear, entire or very nearly so, often fascicled : fls. scarlet.

 fls. scarlet, in terminal racemes. Greenhouse.

ALPINE GAEDENS. In the successful culture of 

 alpine plants, the most important point is to give them 

 as near their natural alpine conditions as possible. So 

 far as soil is concerned this is not difficult, but when it 

 comes to moisture with good drainage and surrounding 

 atmospheric conditions, especially in the dryer atmos- 

 phere of some of our western states, we have a more 

 difficult task. In their natural homes, many of the al- 

 pines are found growing under very similar conditions 

 to our bog plants, and the two classes, for the most part, 

 may be brought together in cultivation. Of course, the 

 mountain Primula might never withstand the stagnation 

 to which the roots of the water Arum (Peltandra Vir- 

 ginica) penetrate in the wet bog, nor should we expect 

 the Peltandra to survive the wintry blasts to which the 

 Primula is exposed, but the two may be grown together 

 with very good results in a moist, springy situation, iu 

 the same bed and soil. Any light, sandy soil, well 

 drained, but through which water is constantly passing 

 in and out, so that there is no stagnation and always a 

 little moisture on the surface (which makes it cooler 

 from the evaporation) , will answer for most of the bog 

 plants and the majority of the alpines also. There 

 should be a natural slope to the surface of the ground 

 for such conditions, and if the surface is undulating, so 

 as to make some parts drier than others, those plants 

 which require the most moisture can go into the wettest 

 places. Alpines like a deep soil, into which their roots 

 can penetrate. Leaf-mold should be used in place of 

 any manure, and if the soil is a very fine one a mixture 

 of gravel should be introduced. Shade and sun are 

 rather necessary, as some of the alpines would hardly 

 stand the full scorching sun of our hottest days in sum- 

 mer, even though the surface of the soil were moist, 

 while others require full sun. Alpines have been suc- 

 cessfully grown in sphagnum moss. This is done with 

 best results in the rockery, where the various pockets 

 are filled with the fresh moss and the plants set in it. 

 Water should be supplied often enough to keep the 

 moss always moist. The evaporation from the wet moss 

 creates a cool atmosphere around the plants, thus giving 

 them a condition somewhat like that which they have in 

 alpine regions, surrounded by mountain fogs, or in the 

 moist bog. Many alpine-garden plants are not confined to 

 alpine situations. They grow in moist places in much 

 lower altitudes as well. Such species as Houstonia 

 ccerulea, Parnassia Caroliniana, and Smilacina steUaia 

 may be mentioned among these. Most of the alpines, 

 when set in the fresh, damp sphagnum, do nicely in full 

 sun, but for the alpine ferns shade should be given. 

 Those which grow in drier places, like the little Woodsia 

 glabella or W. hyperborea, need less shade and moisture, 

 while Asplenium viride and A. Tricliomanes want more 

 moisture about their roots, and deep shade.

ALPlNIA (Prosper Alpinus, an Italian botanist). 

 Scitamindcece. Stove herbs, cult, both for Ivs. and the 

 racemes or panicles of fls. The fl. has 3 exterior parts 

 and 4 interior parts. The lowermost part is lobed or 

 tubular. Stamens with petal-like filament. They need 

 high temperature, much water, light soil, and abundance 

 of room. After flowering, allow them to rest in heat, 

 but do not dry them off. Prop, by dividing the ginger- 

 like roots. 



Alpinia contains many handsome species, but only a 

 few are common in cultivation. They are tropical plants, 

 and require a moist air and a temp, of 55 to 60 F. A 

 mixture of 2 parts loam, 1 part leaf-mold, and 1 part 

 dried cow-manure forms an excellent compost. While 

 growing, they need an abundance of water, and the large- 

 growing kinds require large pots or tubs. The plants are 

 prop, by division in the spring. A. mitans is grown for 

 its handsome fls., and attains a height of 12 or 13 ft. A. 

 rittata is popular tn account of its variegated foliage. 

 A. mutica has very showy fls., but is probably not in the 

 American trade. c ult> by ROBERT CAMERON.
