BOEA 



BOLLEO-CHONDRORHYNCHA 519 



BOEA (name obscure, probably personal). Sometimes 

 spelled Boa-a. Gesneriacex. Allied to Streptocarpus, 

 sometimes found in choice collections. Differs from 

 Streptocarpus in having a short corolla-tube and a 

 broadly campanulate fl., no disk, and very minor 

 characters. Boeas are perennial herbs with ovate or 

 oblique Ivs. radical or opposite on a very short St.: 

 peduncles axillary or elongated leafless scapes, the fls. 

 small or medium in size, blue. Species 16-20 in E. 

 Asia and to Austral, and Seychelles. B. Clarkeana, 

 Hemsl., from China, has been offered in the trade: Ivs. 

 radical, roundish, strongly crenate, petioled, bronze- 

 green above and maroon-red beneath: fls. 3-4 on each 

 peduncle, clear azure-blue with a whitish spot. 



BOEHMERIA (G. R. Boehmer, a German botanist). 

 Urlicacex. A fiber plant; and a greenhouse shrub or 

 tree. 



Leaves alternate or opposite, often 3-nerved: fls. 

 monoecious or dicecious, in dense clusters; petals none; 

 sepals 2-5: fr. a flattened achene. B. nivea, Gaud., of 

 Trop. Asia, is cult, in some countries as a fiber plant, 

 and has been intro. into this country for that purpose. 

 Now grown extensively in Calif, and La. for its fiber. 

 See Report No. 2, office of Fiber Investigations, U. S. 

 Dept. Agric., and Cyclo. Amer. Agric. II, p. 284. It 

 produces ramie. It is a strong-growing, large-lvd. per- 

 ennial, well suited to the border as an ornamental 

 subject. A genus of 45 widely distributed species of 

 shrubs, trees or herbs. 



argentea, Lind. Fig. 588. Tree, 10-30 ft. : Ivs. alter- 

 nate, ovate, long-acuminate, 8-10 in. long, 3-5 in. wide, 

 usually silvery: fls. in an axillary compound catkin-like 

 cluster, 6-10 in. long. Mex. An excellent warmhouse 

 plant, cult, mostly in botanic gardens, but worthy of 

 wide attention. 



B. macrophylla, Don. A shrub or small tree: Ivs. lanceolate, 6-9 

 in. long, serrate, prominently 3-nerved: spikes slender, usually 

 shorter than the Ivs. Himalayan region. |^ TAYLOR 



BOG - GARDENING. The growing of plants in 

 swamps, marsh-spots and bogs: distinguished from 

 water-gardening or aquatic-gardening in the fact that 

 the plants are not immersed or floating but grow 

 mostly free above the soil. When water-gardening is 

 made to include bog-gardening, confusion in practice 

 is likely to result because the cultural requirements are 

 unlike. 



Bog-gardens may be separate areas in themselves, 

 or they may comprise the edges of water-gardens or 

 the spongy ground along runnels or the margins of 

 pools. Bog-gardening is mostly a practice in colonizing 

 plants, finding the ones that are specially adapted to 

 the particular place. The artistic scheme is one of 

 informality. If the place is very soft, stepping-stones 

 may comprise the walks. Hereabouts may be grown 

 the many marsh and wet-land plants, many of which 

 are showy and also little known to cultivators. The 

 sparganiums, pontederias, some of the hibiscus (page 

 338), many orchids, loosestrifes, cephalanthus, utric- 

 ularias, and a host of others wiH occur to frequenters 

 of morasses and distant shores. L. H. B. 



BOLANDRA (H. N. Bolander, Californian botanist). 

 Saxifragdcex. Two species of small W. American herbs 

 offered for borders and wild gardens. 



Flowers purplish in lax corymbs; petals 5, inserted 

 on the throat of the 5-lobed calyx; stamens 5, alternate 

 with petals. Delicate herbs, suitable for rockwork 

 where there is a plentiful supply of moisture. 



oregana, Wats. A foot or 2 high, pubescent and 

 glandular: Ivs. laciniately teothed and lobed: fls. deep 

 purple; tube of the calyx equaling the teeth and a little 

 shorter than the petals : pedicels reflexed in front. Ore. 

 and Wash. Intro, by Gillett in 1881. 



The first-described species, B. calif&rnica. Gray, seems not to 

 have been offcr*-l in thr tr:nlr. It i.s a smaller species, less pubescent 



with smaller fls., the lower Ivs. round-renifonn and 5-lobed: plant 

 3-12 in. high, the sts. weak and slender. 



BOLDOA FRAGRANS, cult, in S. Calif.: Peumus. 

 BOLETUS: Mushroom. 



BOLLEA (in honor of Dr. Karl Bolle). Orchidacese. 

 Epiphytic greenhouse orchids without pseudobulbs, with 

 flat Ivs., and lateral 1-fld. peduncles: sepals and petals 

 nearly alike, spreading, the lateral sepals forming a 

 distinct chin; lip articulated to the column-foot, entire, 

 the margin revolute, furnished with a thick ridged 

 plate, over which the stout column extends; pollinia 4.

violaceum, Reichb. f. (Huntleya violacea, Lindl. 

 Zygopetalum violaceum, Reichb. f.). Fls. deep violet;

 the tip recurved. British Guiana. F.S. 7:678. P.M.

 sepals and petals bluish violet, with yellow tips, the 

 dorsal broadly obovate; petals similar to the dorsal 

 sepal; lip colored like the petals, the crest buff.

BOLLEO-CHONDRORHfNCHA. A cross of Bollea 

 calestis with probably Chondrorhyncha Chesterlonii, 

 with both of which it was found growing in Colombia, 

 whence it was intro. to the collection of Otto Froebel of
