MAXILLARIA 



MAXILLARIA 



fine-rooted species grow on rocks and trees with very 

 little compost attached. The base of the pseudobulbs 

 or rhizome should rest on a convex surface raised a 

 little above the rim of the pot when finished. Maxil- 

 larias delight in a cool, moist, shaded location at all 

 seasons; the winter temperature should not exceed

58 F. by night and not over 60 or 65 by day. Dur- 

 ing summer they must be grown as cool as possible with 

 ventilation at all seasons when admissible, especially 

 in wet heavy weather. Water should be given in 

 abundance while the plants are growing and not too 

 sparingly when at rest, as the plants are subject to 

 spot if kept too dry. Weak liquid cow-manure is bene- 

 ficial occasionally during root-action. Maxillaria has 

 two recognized horticultural groups or sections; viz., 

 caulescent and stemless. The caulescent section 

 embraces M. tenuifolia, M. variabilis and kindred 

 species, having scandent rhizomes and often obscure 

 flowers. These should all be grown under pot culture 

 and afforded supports to climb on, such as small cylin- 

 ders or rafts of open woodwork with a little compost 

 worked in the openings, or osmunda rhizomes supported 

 obliquely in the pots to which the plants can attach 

 themselves as they grow upward, and thus be supplied 

 with moisture for the young roots. To the stemless 

 section belong those with clustered pseudobulbs, as 

 M. grandiflora, M. luteo-alba, M. picta, M. Sanderiana 

 and M. venusta. Some of the these have very showy 

 flowers. Nearly all do best under pot culture. M. 

 Sanderiana and others are exceptions, however, and 

 grow best under basket culture, not too much com- 

 post and an airy position. Demand for maxillarias not 

 being great, the market usually relies on new importa- 

 tions, but stock may also be increased by division 

 between the pseudobulbs as the plants start new action.

1. venftsta, Lind. & Reichb. f. Pseudobulbs oblong, 

 compressed, 2-lvd.: Ivs. oblong-lanceolate, acuminate, 

 plane, 1 ft. long: scapes 6 in. long, bearing a single 

 glistening white fl. 6 in. across; sepals and petals long- 

 lanceolate, acuminate, spreading; the lateral sepals 

 wider, labellum much smaller; middle lobe triangular 

 recurved, obtuse, yellow; lateral lobes very obtuse, 

 bordered with red; disk with a rounded, hairy callus. 

 Winter and spring. Colombia. B.M. 5296. G.C. III. 

 12:367 (abnormal). A large-fld., showy species. 



2. grandifldra, Lindl. Fig. 2336. Pseudobulbs clus- 

 tered, oval: Ivs. erect, plane, keeled, ovate-oblong, 1 ft. 

 long: scapes erect, 3-6 in. long, bearing solitary, large 

 white fls. 3-4 in. across; sepals broadly ovate to oblong; 

 petals ovate-acute, suberect, with recurved tips; 

 labellum saccate, white, much-striped with purple on 

 the sides; middle lobe tongue-like, white, bordered with 

 yellow. Aug. Peru and Colombia. I.H. 17:14. A 

 very showy and beautiful plant. 



3. Lehmannii, Reichb. f. Fl.-stalks nearly 1 ft. long, 

 bearing white fls. nearly as large as those of Ly caste 

 Skinneri; side lobes of the labellum light ocher outside 

 and light reddish brown with chestnut veins inside; 

 middle lobe triangular, wavy, sulfur-color. Ecuador. 

 Resembles M. grandiflora, but distinguished by the 

 character of the lip. 



4. Sanderiana, Reichb. f. Fig. 2337. Pseudobulbs 

 orbicular to broadly oblong, 1-1 M m - long: Ivs. few, 

 6-10 in. long, oblanceolate, plane, keeled: scapes 2-3 

 in. long; fls. 4 in. across, pure white, with the bases 

 of the segms. purplish red, broken upward into 

 blotches; dorsal sepals oblong-obtuse, concave; lateral 

 sepals triangular-ovate, forming a broad mentum at 

 base; lateral lobes of the labellum almost obsolete, 

 middle lobe rounded, crisp, bright yellow, throat dark 

 purple, with a club-shaped callus. Ecuador. B.M. 

 7518. R.H. 1894:526. J.H. III. 26:495. G.M. 52:414.

 and more open: sepals triangular-lanceolate, spreading, 

 3 in. long, pure white; petals shorter and wider, erect, 

 white; labellum fleshy, obovate, somewhat crisp, 

 recurved, pale yellow, with 5-6 red lines on the lateral 

 lobes. S.H. 1:219.
