CALATHEA 



leaved and the large-leaved, although it is a question 

 where to place such intermediate kinds as C.Veitchiana, 

 C. insignis, C. leopardina, C. Sanderiana, C. nigricans, 

 and some others; or we may arrange them in two 

 groups by the red-marked kinds (of foliage), and by 

 the green-, gray- and white-marked kinds, but this 

 would not account for the juvenile and adult stages of 

 C. leopardina, C. imperial, C. Chantrieri, C. ornata, 

 and others. The botanical classification by floral 

 characters would be .of little use to the general horti- 

 culturist. Some plants known in collections as calatheas 

 are likely to be marantas, phryniums, monotagmas, 

 ctenanthe, or others. The radical tufted leaves and 

 capitate inflorescence of Calathea, and the zigzag stems 

 and branched inflorescence and small flowers of Maranta 

 are general characters of separation between these two 

 genera. In the present account, the attempt has been 

 made to draw the characters as much as possible from 

 cultivated specimens apparently authentically named.

A. Markings of If. (upper surface) in red or In-own, at 



least in part. 



1. rdseo-picta, Regel (C. roseo-lineata, Hort.? 

 Mardnta rdseo-picta, Lind. M. Wagneri, Hort.). 

 Dwarf: Ivs. nearly orbicular, purple beneath, the upper 

 side dark green, the midrib red, and an irregular red 

 zone (sometimes two zones) two-thirds of the distance 

 from the midrib toward the margin. Amazon. F.S. 

 16:1675-6. Gn. 2, p. 3. 



2. Pavdnii, Kcern. (C. tubispatha, Hook. f.). Two 

 feet or less high: Ivs. obovate-elliptic, short-acuminate 

 or cuspidate, thin, greenish beneath, lively green above, 

 and marked midway between the rib and the margin 

 with lighter green and squarish patches of brown. 

 Peru. B.M. 5542. 



3. angustifdlia, Koern. (Mardnta discolor, Hort.). 

 Habit loose, erect, only slightly spreading at apex: 

 growths bearing 1-4 Ivs. from 1-5 ft. high; blade 

 lanceolate, unequilateral, %-2 ft. long, rich light green 

 with fine lines of purple-red above, rich shining red 

 beneath; petiole erect, stout, 1-3 ft. high, rich dark 

 red, heavily marked with light green tuberculate 

 spots; sheath extending from one-third to one-half its 

 length: in the juvenile form the whole of the plant is 

 densely covered with reddish brown hairs, but in the 

 adult plant, the blade is almost entirely glabrous. 

 Cent. Amer. B.M. 8149. 



AA. Markings of If. mostly on the order of green or white 

 (exceptions in juvenile stages of Nos. 35, 86, 37 

 and others). 



B. Lf. -blades small or short, usually less than 12 in. long. 

 c. Under side of Ivs. green, grayish, or yellowish (violet 



informs of No. 14). 



4. micans, Kcern. (Mardnta micans, Math. Phry- 

 nium pumilum, Klotzsch). Very small: Ivs, 2-3 in. 



736. Tuber of calatljea. 



(XH) 



CALATHEA 



long, and 1 in. wide, oblong-lanceolate, somewhat 

 acuminate, green and shining above, the rib in a feath- 

 ered white stripe, paler beneath. Brazil. Probably 

 the smallest cult. Calathea. 



5. chimboracensis, Lind. Dwarf: Ivs. oblong-ovate, 

 8-12 in. long, acuminate, green above and below, with a 

 very dark green white-margined band running length- 

 wise the blade midway between the rib and each mar- 

 gin. Neighborhood of Mt. Chimborazo. I.H. 17:6. 



6. Wiotiana, Makoy (Mardnta Widtii, Morr.). 

 Habit dwarf, spreading: rhizomes branching freely: 

 growths bearing only a single If. each; blade linear- 

 lanceolate, slightly oblique, 4- 

 12 in. long, undulate, acute, 

 upper side silvery gray with a 

 narrow band of light green 

 around the margin ; midrib green, 

 with a row arranged pinnately, 

 along either side of the midrib, 

 of dark olive-green blotches or 

 stripes; under side dull grayish 

 green finely striated all over 



between the principal veins with patches of light 

 yellowish green; petiole 3-15 in. long, erect or spread- 

 ing-, light green, terete sheath entirely absent. Prob- 

 ably Brazil. A most beautiful species; thrives best in 

 leaf-mold and sand. 



7. trifasciata, Kcern. (Phrynium propinquum, Poepp. 

 & End!.). Habit dwarf, spreading, with short free- 

 branching rhizomes: growths bearing 1 If. only; blade 

 cordate-ovate, unequilateral, 3-12 in. long, apex acute, 

 and half twisted around, upper side silvery gray shading 

 to green at the margins and with a row on either side 

 of the midrib of dark green stripes arranged pinnately, 

 under side light green, prominently striated on both 

 upper and lower sides with a network of fine veins 

 connecting all the principal lateral veins; midrib pale 

 yellowish brown on the under side and covered with 

 dark brown hairs in the lower half and extending for 

 an inch or more on the apex of the petiole; petiole 3-12 

 in. long, light green, glabrous except in the upper inch 

 or so; scale Ivs. reddish brown. Guiana. A companion 

 plant to C. Wiotiana, to which it is closely allied, but 

 differs in the broader and paler color of the Ivs. Of 

 easy cult. 



8. fasciata, Regel & Kcern. Habit dwarf, compact: 

 Ivs. 10-18 in. long, reflexed; growths bearing 1-3 Ivs.; 

 blade broadly ovate or orbicular, acute or obtuse, 

 glabrous 5-10 in. long, slightly undulate; upper side 

 rich dark olive-green alternately marked by trans- 

 verse bars of silvery white; under side dull grayish 

 green; petiole 4-8 in. long, spreading, dull green, 

 covered with short and minute brownish hairs; sheath 

 extending up to one-half the length of the petiole, 

 upper part terete. Brazil. Gn. 2, p. 3. Considered by 

 some to be a variety of C. rotundifolia, Koern. C. 

 farinosa and C. ovalifolia are probably stages in the 

 development of this plant or perhaps slight varieties. 



9. Luciana, Hort. Habit medium to strong, compact, 

 more or less tufted: growths with 2-5 Ivs., usually 

 with 3, arching over at the tips and J^-3 ft. high; 

 blade elliptic, oblique, glabrous, acute, slightly undulate, 

 3-12 in. long, upper side light pea-green feathered 

 along the midrib with pale greenish white and with a 

 concentric zone of the same shade near the margin of 

 the If., under side dull grayish green; petiole erect, 

 slender, rigid, pale green, glabrous or nearly so; sheath 

 extending from one-half to nearly the entire length of 

 the petiole, upper part oval, slightly flattened on each 

 side: infl. a short few-fld. spike; peduncle 1-3 in. long; 

 bracts spreading or erect, ovate, light reddish brown, 

 \}/2 in. long; fls. in pairs, yellow; sepals thin, linear, 

 one-third the length of the tube; corolla yellow; petals 

 elliptic, %in. long, spreading, acute; the 2 petaloid 

 aborted stamens obovate, J^in. long, bright yellow,
