But the name vanadium has been maintained, and that of erythronium has never been received. Metallic van a- dium, as prepared by reducing the chlorid in hydrogen gas, is a light-gray powder, which under the microscope has a brilliant silvery luster: it has a specific gravity of 5.5; it is very little acted on by air or moisture at the or- dinary temperature; it is easily di olved in nitric acid, but is not at all acted on by hydrochloric acid, and is af- fected by strong sulphuric acid only when heated. Vana- dium belongs to the antimony group, and, like the other members of this group, is in its chemical relations close- ly connected with the elements of the nitrogen group. Vanadium is an element whose combinations seem to be quite widely distributed, although occurring only in small quantity. The most abundant vanadium mineral is van a- dinite, which is a vanadate of lead with chlorid of lead, and has been found in numerous widely separated local Vandal (van'dal), n. and a. [= F.

(Lindley, 1833), Vanda + -ex .] A tribe of orchids, charac- terized by a single posterior opercular anther, its cells almost always confluent at maturity, and closely incumbent above a horizontal ros- tellum, to which the waxy pollen-ma es are affixed by a small thick or scale-like gland, which is often prolonged into a distinct cau- licle or stalk. It includes about 140 genera, cla ed in 8 tribes, the types of which are the genera Eulophium , Cymbidium , Cyrtopodium , Stanhope a , Maxillar i a , Onci- dium , Sar canthus , and Notylia . These genera alone in- clude over 530 tropical species, and are all, except per- haps the first and last, highly prized in cultivation. The Notylieæ (or Podochileæ ) are aberrant in their erect ros- tellum, and are thus transitional to the tribe Neottieæ . The two globose or oblong pollen-ma es, each sometimes bisected, are very readily removed by insect or artificial aid, and insure cro -fertilization. The genera are nearly all epiphytic. They often produce pseudo-bulbs, but not tubers; their stems are erect, or reduced to a creeping rootstock adhering to trees or stones; their inflorescence is usually lateral, very rarely, as in Cyrtopodium , a ter- minal raceme. The flowers are commonly large and hand- some, many of the most valuable among orchids belong- ing here, as Aërides , Miltonia , Saccolabium , Odontoglos- sum , Phalænopsis , Zygopetalum , Lycaste , Catasetum , and Peristeria. See cut under Phalænopsis . Van dell i a (van-del'i-ä), n. [NL. (Linnæus, teen sepals, six shorter nectary-like petals and as many stamens, and a capsule opening into valves. The named after the Italian Vandelli , who type of the subtribe Vandellieæ . It is dist in- guished from the related genus Ilysanthes by its four perfect stamens. There are about 30 species, natives of warm parts of the Old World, 2 species, V. crustacea and V. diffusa , occurring in tropical America. They are usu- ally much-branched annuals, with opposite leaves, and small flowers which are solitary in the axils, or form a terminal raceme or umbel. See bitter - blain .
