growing period, because they are not conveniently 

 transplanted. Three plants may be placed in 6-inch 

 pans, keeping them close to the side of the pan in 

 triangular form. A good growing medium consists of 

 two parts peat soil, one part fibrous loam and one part 

 sand, with plenty of drainage. When in full growth, the 

 top of the pan will be fully covered by the viscid leaves. 

 Watering the plants from above should not be prac- 

 tised because of destroying the dew-like deposit on the 

 surface of the leaves. The pans should be placed in 

 saucers of water, and set in a light position in the warm- 

 house; give plenty of sunshine and the plants will 

 readily flower throughout the summer. In October 

 place the plants in the cool end of the house to rest. The 

 growth will gradually deteriorate until it assumes the 

 rosettes of small succulent leaves to carry them through 

 the resting period. Young plants are propagated 

 almost as readily as echeverias. The small rigid leaves 

 should be carefully broken from the mam stem; if not 

 broken clean they will not reproduce young plants. 

 These should be laid flat on sand in pans of convenient 

 size; the top of the pan should be protected by glass 

 or a bell-jar, to retain the moisture} place the pan 

 in a saucer of water. In four to six weeks the young 

 plants with the leaf attached will be sufficiently rooted 

 to allow potting. One of the worst pests are wood- 

 lice. (G.H. Pring.) 



A. Color of fls. yellow. 



Ixltea, Walt. Exceptional by reason of its yellow fls. 

 and nearly regular (not 2-lipped) corolla: variable in 

 the size of all its parts, and in the obtuse toothing of the 

 corolla-lobes: Ivs. ovate to oblong-ovate: scapes 5-12 

 in. high; fls. %-!% i n - l n g and broad; spur curved, 

 about as long as the rest of the corolla; throat spotted 

 and lined with red; palate very prominent and densely 

 bearded. Low pine barrens, N. C. to Fla. and La. B.M. 

 7203. B.R. 126. 



AA. Color of fls. purple to lilac. 

 B. Spur 2 or 4 times as long as remainder of the corolla. 



caudata, Schlecht. (P. orchidioides, A. DC. P. Bakeri- 

 dna, Hort.). Lvs. in dense rosettes when young, long 

 and narrow; on older plants few and large, obovate and 

 obtuse: scapes 5-7 in. high; fls. deep carmine, with 

 lighter throat and reddish lines, attaining 2 in.; lobes 

 all rounded except the middle one of the lower lip, 

 which is retuse. Mex. B.M. 4231. G.C. II. 15:541. 

 R.H. 1902:456. Gn. 23, p. 309. G. 29:181. G.W. 9, 

 p. 482; 12, pp. 308-10. Var. superba, Hort. Fls. rich 

 rosy carmine with white eye, about 2 in. long and nearly 

 as broad. According to W. Watson, England, P. 

 caudata "is largely grown by orchid-breeders, who find it 

 an excellent trap for the tiny midge-like fly which lays 

 its eggs in orchid seedlings when they are very young. 

 . . . It is a most charming little pot-plant, and has 

 become a favorite in many gardens." 



Rosei, W. Wats. Very like P. caudata and perhaps a. 

 form of it, but the fl. deep violet-purple, almost a blue, 

 nearly 2 in. across and remaining fresh for weeks. 

 Prop, from the fleshy Ivs. Mex. G.C. III. 49:82. 



gypsicola, Brandeg. Plant 3-4 in. high: Ivs. when 

 plant is in bloom linear from a rather broad base, about 

 2 in. long, revolute on margins, with viscid glandular 

 hairs on upper surface; later or winter Ivs. spatulate- 

 oblong and cotyledon-like, in a very dense rosette: fl. 

 purple, with a very short white tube; upper lip 2-parted 

 into linear-oblong lobes; lower lip 3-parted into similar 

 lobes; spur more than 1 in. long, slender, purplish, 

 2-toothed at tip. Mex. B.M. 8602. 



BB. Spur about as long as remainder of the corolla, 

 c. Fls. %-l in. long and broad. 



grandiflora, Lam. Scapes 3-8 in. long; fls. "blue, 

 rarely purplish violet," according to De Candolle, 



10-15 lines long, 9 lines broad (3 or 4 times longer than 

 in P. vulgaris) ; lobes undulate; palate with 1 or 2 white 

 spots; spur straight, a trifle shorter than the broadly 

 funnel-shaped tube. W. Eu. G.C. III. 10:373. Ac- 

 cording to Bentham, this is a large-fld. variety of P. 

 vulgaris, with longer spur and broader lobes, which 

 in the western part of Eu. passes into the common 

 form. 



hirtiflSra, Tenore. Scapes 3-4 in. high; fls. 8 lines 

 long and broad, lilac or rose (blue according to Tenore, 

 and shown as purple in B.M.), with a white tube; spur 

 straight or curved, about as long as the rest of the 

 corolla. S. Eu. B.M. 6785. Gn. 25, p. 291. G. 11:251. 

 Possibly distinguished from P. grandiflora by the 

 color of the tube, which is white outside and yellow in 

 the throat. According to Burbidge there is a variety 

 with pure white fls. 



cc. Fls. %in. long and broad. 



vulgaris, Linn. According to Hooker, this differs from 

 P. hirtiflora in the bright blue color and the retuse 

 lobes of the corolla, as also in the less globose caps.: 

 scapes 1-5 in. high; fls. bluish purple or violet, about 

 6 lines long; spur nearly straight, about 2 lines long 

 or as long as the rest of the corolla. Wet rocks, Eu., 

 Asia, New England, and north and westward. Gn. 

 57, p. 335; 69, p. 101. Sometimes called "Labrador 

 violet." 



P. eldtior, Michx., in N. C. to Fla., is a beautiful species that 

 should be in cult.: plant 3-5 in. across and 10^12 in. tall: Ivs. 

 viscid-glandular, in pale green rosettes: fls. whitish purple, to % 



in - broad - WILHELM MILLER. 



PINK: Dianthus. L. H. B.f 



PINUS (ancient Latin name). Pindcese. PINE. PINE- 

 TREE. Ornamental trees grown for their handsome 

 evergreen foliage and symmetrical or picturesque habit, 

 some also for their conspicuous large cones; many spe- 

 cies are valuable timber trees. See Pine. 



Resinous evergreen trees with usually whorled 

 branches, rarely shrubby: winter buds covered with

 Austrian pine; also, at bottom, a young pis- 

 2956. Staminate cone tillate cone (natural size), a, front view 

 of Pinus rigida. (X2) of two ovules; c, side view. 



imbricate scales: Ivs. of 2 kinds; the primary Ivs. are 

 spirally arranged and as they appear on young seedling 

 plants and occasionally on shoots from the old wood, 

 are green and subulate, but commonly they are reduced 

 to small scarious bracts bearing in their axils the 

 acicular, semi-terete or triangular secondary Ivs. borne 

 on an undeveloped branchlet in clusters from 2-5, or 

 occasionally more, rarely reduced to 1. surrounded at the 

 base by sheaths of 8-12 bud-scales: fls. monoecious; the
