CALYPSO 



CAMASSIA 



639 



within; column petal-like, ovate, bearing the lid-like 

 anther just below the apex. Maine to Minn, and N.; 

 also Eu. Abundant in parts of Ore. and Wash. B.M. 

 2763. G.C. II. 16:656. 



CALYPTROGYNE (from calyptra, hidden, and gyne, 

 woman, in allusion to the half-hidden gynoecium). 

 Palmacese, tribe Geonbmese. Short, almost completely 

 stemless and unarmed palms with unequally pinnate 

 terminal leaves. 



Stems frequently stoloniferous, when present, ringed 

 below: Ivs. numerous, often with the pinnate segms. 

 joined together, in extreme youth 4-parted instead of 

 bi-partite as in most related genera; Ifts. somewhat 

 irregularly disposed on the rachis, broadly or narrowly 

 scythe-shaped, running at the tip to an abrupt point, 

 at the base revolute; petiole very short or practically 

 none: spadix simple or sometimes branched at the base, 

 long-stalked; spathes 2; fls. a little unequal, with 3 

 sepals, 3 petals and 6 stamens, the style half immersed 

 in the spadix: fr. oblong or obovoid, 1-seeded. About 

 4 species, all from Trop. N. Amer. From Geonoma, a 

 near relative and horticulturally a much more impor- 

 tant genus, Calyptrpgyne is distinguished only by the 

 almost stemless habit, and the purely technical charac- 

 ter of having prominently arrow-shaped anthers. In 

 Geonoma the anthers are pendulous, but not 

 sagittate. 



Calyptrogynes are handsome palms, seldom seen out- 

 side of large collections. Special care must be given to 

 the soil so that it will be sweet and porous, especially 

 after the plants leave the seed-pan. Well-drained pots 

 and a little charcoal mixed with the soil, and the plants 

 kept in a uniformly moist state, are conditions essential 

 to the healthy growth of the plants. In this genus, C. 

 Ghiesbreghtiana is the most widely known species, 

 another garden name for which is Geonoma Verschaffeltii. 

 These are shade-loving palms, having leaves of compara- 

 tively thin texture, and consequently are subject to 

 attacks of red spider unless properly cared for in regard 

 to moisture. Calyptrogynes are most useful in a small 

 state, old plants in general being rather leggy and poorly 

 furnished. (G. W. Oliver and W. H. Taplin.) 



754. Calypso borealis. 



glatica, H. Wendl. (Gednoma glauca, Oerst.). Practi- 

 cally stemless: Ivs. 4-5 ft. long, the sheathing petiole 

 brownish, about 1 ft. long; Ifts. numerous, about 2-3 

 in. apart, with 4 principal nerves, and scarcely any 

 secondary ones: 

 spadix simple, dif- 

 fering from the 

 following species 

 in which the 

 spadix is often 

 branched, 2-3 ft. 

 long, the pistillate 

 fls. half hidden in 

 tiny pits. Cent. 

 Amer. G.C. III. 

 30:179. Not a 

 common species, 

 but young plants 

 are specially at- 

 tractive. 



Ghiesbregh- 

 tiana, H. W T endl. 

 (Gednoma Ghies- 

 breghtiana, Lindl. 

 & H. Wendl. G. 

 magmfica and G. 

 Verschaffeltii, 

 Hort.). St. short 

 or almost none: 

 petiole 5 ft. long: 

 Ivs. elongate-oval; 

 segms. in 6 pairs, 

 unequal, almost 

 opposite, rather 

 remote, lanceo- 

 late, very long- 

 acuminate, fal- 

 cate, the 2 upper- 

 most on each side 

 very wide: spadix 

 often branched 

 below, the fls. half hidden in tiny pits. Chiapas, Mex. 

 B.M. 5782. 



C. starapigu&nsis, H. Wendl. St. short: Ivs. 6 ft. long. Costa Rica. 

 G.C. III. 29:217, desc. C. spicigera, H. Wendl. St. evident: Ivs. 

 irregularly pinnate, 3 ft. or less long, the stalks flat on upper side. 

 Guatemala. C. Swdrtzii, Hort., is a Geonoma. j^ TAYLOR 



CALYPTROSTfGMA. Diervilla Middendorffiana. 

 CALYSTEGIA: Conwlwlu*. 



CAMAROTIS (a vault, in reference to the cavity in the 

 apex of the lip). Orchidacex. Epiphytic hothouse orchids. 



Stems elongated, with short Ivs., and many-fld. 

 racemes: sepals and petals similar, spreading; lip 

 spurred, 3-lobed; rostellum and anther beaked; poll in i a 

 2, upon long thin sjtipes. Species 2, in E. India. 



rostrata, Reichb. (C. purpiirea, Lindl. Sarchochllus 

 purpitreus, Benth.). Fig. 755. Sts. 2-3 ft. long, climb- 

 ing: Ivs. oblong-linear, bifid at apex, 3-4 in. long: 

 racemes longer than Ivs.; fls. crowded, about 1 in. 

 diam., rose-purple, the lip somewhat darker. India. 

 P.M. 7:25. A scarce plant, now offered in American 

 lists. Free-growing plant with aerial roots similar to 

 some epidendrums. The treatment accorded to the 

 vandas and saccolabiums with similar roots will suit 

 the camarotis. GEORGE V. NASH. 



CAMASSIA (Quamash or Camass is the Indian 

 name). Sometimes written Quamasia. Liliacese. 

 CAMASS. West American spring-flowering bulbs. 



Leaves all radical, long-lance-shaped, sheathing, 

 from a true bulb that is pointed and with a rounded 

 rather flattened base: sts. erect, 2-3 ft., bearing many 

 bracted blossoms that open from the bottom of the 

 raceme upward, in long succession: fls. blue, purple, 

 white or cream, with 6 spreading 3-7-nerved segms., 



755. Camarotis rostrata.
