RODRIGUEZIA 



ROLLINIA 



sheathing Ivs. at the base: racemes erect or pendulous; 

 dorsal sepal and petals similar, free, erect; lateral sepals 

 united, concave, but scarcely saccate; labellum spurred 

 or saccate, with a long claw parallel to the column, and 

 a spreading blade usually exceeding the sepal; column 

 slender. Robert Brown's genus Gomesa (sometimes 

 written Gomeza), founded on G. recurva, is by some 

 referred to Rodriguezia. See Gomesa. The fls. are 

 nearly always fragrant. The plants vary somewhat in 

 habit. Some species form neat, compact tufts, while 

 others, like R. decora, have long, straggling rhizomes 

 difficult to keep within the limits of a block or a basket. 

 Rodriguezias should be grown in very shallow pots 

 filled with tough peat, and well drained. Rest them in a 

 temperature of 50, giving little water. The growing 

 temperature should be from 65 to 75. Give plenty of 

 moisture and shade from direct sunshine. The stronger- 

 growing kinds will need thicker potting material in 

 baskets; they do well wired on tree-fern stocks. During 

 growth, syringing is necessary. (Wm. Mathews.)

 into a concave, bifid blade, saccate at base; petals obo- 

 vate, with the apex recurved; labellum with a broadly 



cuneate, bifid middle lobe, longer than the sepals and 

 petals; base and lateral lobes parallel to the column, 

 throat with many lamellae. April, May. Guiana. B.R.

 dulous, from the tuft of Ivs.; fls. pure white; labellum 

 2-lobed, hastate; lateral lobes erect, with lamellae!; col- 

 umn pubescent, in which it differs from other species.

secunda, HBK. Fig. 3421. Pseudobulbs bearing 

 several thick, linear-oblong Ivs. : raceme erect, secund, 6 

 in. high; fls. deep rose; sepals erect, ovate, convex, the 

 lower pair keeled and gibbous; petals like the dorsal 

 sepal; labellum obovate-oblong, emarginate, scarcely

RCETTLERA, also spelled Rottlera: Chirita. 

 ROGIERA: Rondeletia. 



ROHDEA (Mich. Rohde, physician and botanist of 

 Bremen). Sometimes spelled Rhodea. Lilidcese. A 

 monotypic genus of Japan and China, essentially a 

 tender foliage plant with numerous radical Ivs. 6-18 in. 

 long: fls. borne among the Ivs. in short thick dense 

 spikes a few inches high; perianth globular-bell-shaped; 

 anthers sessJe; stigma peltate; style nearly wanting: fr. 

 a globular, usually 1-seeded berry. Rohdeas are excel- 

 lent plants for dwelling-house decoration, doing well in 

 the cooler positions. They are perfectly hardy at 

 Washington. 



japdnlca, Roth. Root a long nearly cylindric root- 

 stock with fleshy fibers: Ivs. typically green, 9-12 in a 

 rosette, erect, oblanceolate: berry about the size of a 

 small olive, with a red pulp. B.M. 898 (as Orontium 

 japonicum). Gn. 30, p. 541. The following varieties, 

 which differ in shape and color of the Ivs., have been 

 offered by Dutch bulb-growers: Vars. a&reo-striata, 

 falcata, latimaculata, macrophylla, marginata minor, 

 pygmsea, zebrina. This plant known as Omoto or 

 Mannensei is a favorite among the Japanese, and fine 

 specimens often bring as much as $500, even when 

 only a few inches high. The seven standard varieties 

 of Japan are Hinomoto, Nagashima, Kyuanji, Shikami, 

 Daimyosei, Jindai, and Akitsushima. Retired persons 

 of means often spend their declining years in the cul- 

 ture of this interesting plant, of which hundreds of 

 named varieties are known to Japanese fanciers. A 

 number of very beautiful books have been written on 

 this plant, and it has an extensive literature. This 

 plant is well known in China and was adopted by the 

 Manchus as their national flower. L. jj_ g f
