RODRIGUEZIA 



tufts, while others, like It. decora, have long, strag- 

 gling rhizomes difficult to keep within the limits of n 

 block or a basket. Pseudobulbs small, compressed, 1-2- 

 Ivd. and bearing 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 (iomeza), found on 

 G. recurva, is now referred to Rodriguezia. G. recurva 

 is It. I'llatiifuliii. 



Grow Rodriguezias in very shallow pots filled with 

 tough peat, and -A-ell drained. Rest them in a tempera- 

 ture of 50, giving little water. The growing tempera- 

 ture should be from 65-75. 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 season 

 of growth, syringing is necessary.

 dorsal sepal obovate, emarginate, the lower pair united 

 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, furnished with 

 lamella?; column pubescent, in which it differs from the 

 other species.

ROHDEA (Mich. Rohde, physician and botanist of 

 Bremen). Liliaceui. A raonotypic genus from Japan, 

 essentially a tender foliage plant with luxuriant radical 

 Ivs. 1-2 ft. long. The fls. are borne among the Ivs. in 

 short, thick, dense spikes a few inches high; perianth 

 globular-bell-shaped; anthers sessile; stigma peltate; 

 style nearly wanting: fr. a globular, usually 1-seeded 

 berry. Rohdeas are excellent plants for dwelling- 

 house decoration, doing well in the cooler positions. 

 They are perfectly hardy at Washington, the foliage 

 being but slightly browned during the coldest weather. 



Japdnica, 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. Gn. 30, p. ."41. 

 The following varieties, which differ in shape and 

 color of the Ivs., are offered by Dutch bulb growers: 

 Vars. aureo-striata, falcata, falcata var., latimaculata 

 macrophylla, margiuata minor, pygmaea, zebrina.

ROLLINIA (Charles Rollin, of Paris, 1661-1741, aided 

 Tournefort). Anondcew, About 20 trees and shrubs of 

 tropical America, differing from Anona in having the 

 petals united into a 3-6-lobed tube, the exterior lobes 

 wing-appendaged, the interior small or none: fr. some- 

 times of separate carpels: fls. 1-5 on peduncles that are 

 terminal or opposite the Ivs. The general remarks un- 

 der Anona will apply to these plants. 



Sieberi, A. DC. (Anona tnuscdsa, Jacq.). Low tree, 

 the young growth nearly or quite smooth: Ivs. oblong, 

 taper-pointed, smooth: exterior petals oblong and blunt 

 (%-l in. long), greenish, the interior smaller but promi- 

 nent, reddish: fr. about 4 in. in diameter, greenish, 

 somewhat globose, the surface bearing tubercles. Na- 

 tive in the islands of Guadeloupe and Martinique, and 

 in Guiana; probably in various West Indies islands. 

 Introduced into southern Florida as a fruit plant, but it 

 is yet very little known within our limits. L. jj. g.
