ZYGOPHYLLUM

maxillare, Lodd. Pseudobulbs 2 in. long: Ivs. lanceo- 

 late, 1 ft. long: scape 9 in. long, 6-8-fld.: fls. 1^ in. 

 across; sepals and petals ovate-oblong, acute, green, 

 with transverse brown blotches; labellum horizontal, 

 purple, with a very large, glossy purple, notched horse- 

 shoe-shaped crest, middle lobe roundish, waved, and 

 obscurely lobed. Winter. Brazil. B.M. 3686. L.B.C. 

 18:1776. J.H.III.33:295. P.M. 4:271. Distinguished 

 by its small fls. and very large crest. 



cc. Labellum pubescent. 



crinitum, Lodd. Habit of Z. intermedium: Ivs. broadly 

 linear-lanceolate: fls. on long, stout scapes; sepals and 

 petals 2 in. long, oblong-lanceolate, green with rather 

 few brown blotches; labellum 2 in. across, spreading, 

 wavy, scarcely emarginate, white with purple veins 

 radiating from the thick crest, disk hairy. Fls. at 

 various times. Brazil. L.B.C. 17:1687. B.M. 3402 

 (as Z. Mackaii var. crinitum). This has fewer brown 

 blotches on the sepals and petals than Z. intermedium. 

 There are varieties with pink, blue, or almost colorless 

 veins on the labellum. Var. caeruleum, Hort., has the 

 veins deep blue. G.M. 46: 153; 50: 59. J.H. 111.46:197. 



intermedium, Lodd. Lvs. ensiform, 1^ ft. long, 

 1^2 in. wide: scape longer than the Ivs., bearing 5-6 

 fls. each nearly 3 in. across: sepals and petals oblong, 

 acute, green with large, confluent blotches of brown; 

 labellum rotund, narrowed at the base, deeply 2-lobed 

 in front, pubescent, bluish white with radiating broken 

 lines of purplish blue; column green and white. Fls. 

 in winter. Brazil. R.H. 1873:190 (as Z. Rivieri). 

 Plants of Z. Mackaii are often cult, under this name. 



DD. Petals uniformly colored. 



Sedenii Reichb. f. Plants strong, with the scape, 

 about as long as the Ivs. and bearing several fls. : sepals 



and petals deep purple-brown, bordered with green; 

 labellum pale purple in front, becoming deep purple 

 toward the base. F.M. 1880:417. Gt. 28:265. A 

 garden hybrid raised by Veitch. 



Z. Arnustrongia:=Z. Mackaii xZ. rostratum. Z. Bdttii, Rolfe. 

 Fls. white, the sepals purple-tinged, the petals and lip blotched with 

 bright rose-purple. G.C. III. 27: 149. G.M. 48:365. Z. Biirtii,

 genus, greenish, fragrant, hairy inside. Z. coeleste, Reichb. f.=

GEOEGE V. 



ZYGOPHYLLUM (yoke leaf, from the paired or 

 opposite Ifts. or Ivs.). ZygophyUacese. Small often 

 spiny twiggy shrubs or subshrubs, with stiff branches, 

 of about 60 species in Eu. and Asia but mostly in S. 

 Afr. and Austral., apparently not in the American 

 trade but likely to be planted for ornament now and 

 then by amateurs in the warmer and drier parts of the 

 country. Lvs. simple or 2-foliolate: fls. white or yel- 

 lowish or red, on 1-fld. peduncles; calyx 4-5-parted; 

 petals 4 or 5, clawed, twisted; stamens &-10; disk 

 fleshy and angled; ovary 4- or 5-celled, sessile: fr. an 

 angled or winged caps. Prop, by seeds or cuttings. The 

 species most likely to appear in collections are per- 

 haps Z. Fabago, Linn., the Syrian bean-caper, with 

 obovate Ifts., copper-yellow fls., deep strong root and 

 nearly or quite herbaceous top, S. W. Asia; Z. Morg- 

 sana, Linn., with obovate obtuse Ifts., long yellow 

 petals, and shrubby habit, from S. Afr.; Z. spindsum, 

 Linn., with linear Ifts., yellowish or whitish nodding 

 fls., a small bush only 1-2 ft. high, from S. Afr.
