BOEA 



BOLLEO-CHONDRORHYNCHA 519 



B06A (name obscure, probably personal). Sometimes 

 spelled Bos-a. Gcsneriacex. Allied to Streptoeari)US, 

 sometimes found in choice collections. Diffens 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 mediiun 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). 

 Urticdcese. A fiber plant; and a greenhouse shrub or 

 tree. 



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

 monoecious or dioecious, 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 extensivelj- in Calif, and La. for its fiber. 

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

 Dept. Agric, and Cyclo. Amer. Agric. H, 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 silverj': 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. macrophiJlUi, Don. A shrub or small tree; Ivs. lanceolate, 6-9 

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

 shorter than the Ivs. Uimalayan region. Ttr T* » yi OR 



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 

 unhke. 



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 

 informaUty. 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 know^n to cultivators. The 

 sparganiimis, pontedcrias, some of the hibiscus (page 

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

 ularias, and a host of others will occur to frequenters 

 of morasses and distant shores. L_ jj b_ 



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

 Saxifragacese. Two species of small V\'. American herbs 

 offered for borders and wild gardens. 



Flowers purplish in lax corj'mbs; 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 toothed 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. califdrnica. Gray, seems not to 

 have been offered in t lie t rade. It is a smaller species, less pubescent 



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

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



BOLD 6 A FRAGRANS, cult, in S. Calif.: Peumus. 



BOLETUS: Mushroom. 



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

 Epiphytic greenhouse orchids without pseudobulba, 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.
