of some South American Sapotacece. 

 Muruxi Bark, the astringent bark of 

 Byrsonima spicata, used by the Brazilian 

 tanners. Niepa Bark, the febrifugal bark 

 of Samadera Indica. Panococco Bark, the 

 sudorific bark of Sioarlzia tomentosa. Quer- 

 citron Bark, the yellow dye bark of Qwer- 

 cus tinctoria. Quillai Bark, the bark of 

 Quillaia saponaria, used as a substitute

 Bark. Winter's Bark, the tonic aromatic 

 bark of Drymis Winteri. Worm Bark, 

 the bark of Andira inermis, formerly 

 used as an anthelmintic. There are 

 other barks, but these are the principal 

 ones having a commercial or medicinal 

 value. 



drred. Crossed by a paler color in spaces 

 resembling bars, as in Sanseviera Ja- 

 vanica. 



arringtoniacece, (Barringtoniads.) A small 

 family, usually considered as forming a 

 tribe of Myrtacece, with which they agree 

 in the structure of their ovary and 

 perianth, and in the numerous perigy- 

 nous (which see) stamens, turned inward 

 on the bud; the chief difference consisting 

 in the presence of albumen in the seed. 

 The leaves are alternate, not dotted, and 

 often serrated; these characters, how- 

 ever, also occur occasionally in true Myr- 

 tacece. There are about five hundred and 

 twenty species. They are all trees or 

 shrubs, and inhabit the tropics of the 

 New and the Old World. Some of them 

 bear large flowers of considerable beau- 

 ty. The principal genera are Barring- 

 tonia and Careya in the Old World, and 

 Gustavia in the New. 



BAS 



Barringtoniads. The English term for Bar- 

 ringtoniacece. 



Baru. A woolly material found at the base 

 of the leaves of Saguerus saccharifer, 

 sometimes called Arenga saccharifera. 



Basal. Growing at the base of anything, 

 or attached to the base of any organ or 

 part. 



Base. The end nearest to the point of at- 

 tachment; the lowest part. 



Base-burning Water Heater. The name of a 

 boiler in use for small green-houses or 

 conservatories. See Heating by Hot 

 Water. 



BaseUacece, (Basellads.) A small family con- 

 sisting chiefly of herbaceous climbers, 

 with leaves more or less succulent, and 

 small, inconspicuous flowers. They are 

 distinguished from Chenopodiacece by 

 what has been called a double calyx, and 

 the perigynous stamens; but the so-called 

 outer calyx consists merely of the two 

 bracts, which are here attached to the 

 perianth, instead of being free, or at some 

 distance from it; and stamens more or 

 less perigynous occur also in other che- 

 nopodiaceous genera. BaseUacece have, 

 therefore, been now reunited with that 

 family as a tribe. The perianth is usu- 

 ally thick and fleshy, and the style is 

 three-cleft, while in true Chenopodiacece 

 it is more frequently, but not always, 

 only two-cleft. There are about seven- 

 teen species, all of which are tropical, 

 and have been distributed into six gene- 

 ra, of which the most important are Ba- 

 sella, Boussingaultia, and Anredera. 

 Basellads. The English name for BaseUa- 

 cece. 



Basibractwlate. A term applied chiefly to 

 the involucre of a Composite when it is 

 surrounded at the base by a distinct or- 

 der of bracts, as in Dandelion.
