HENDERSON'S HANDBOOK OF PLANTS 



VAE 



Variolate. Marked as if by the pustules or pit- 

 tings of small-pox. 



Varnisli Tree. A common neime for Ailcmtus 

 glandulosus, Rhus vemicifera, etc. 



Vascular. Furnished with, or relating to ves- 

 sels or ducts. 



Vasoulum. A botanist's collecting-box. The 

 term is also applied to a pitcher-shaped leaf. 



Vases. These are formed of iron, stone, earth- 

 enware etc., and are usually raised on a pedes- 

 tal to a height of four or five feet. They are 

 of various sizes and patterns. The bowls for 

 the soil vary in depth from six to eighteen 

 inches ; but in all cases holes must be made 

 In the bottom (if not already there) to allow 

 free drainage for water, for, without these 

 (and some are made without them), the soil 

 would soon get saturated and sour. Almost 

 the same character of plants is used for plant- 

 ing vases as for window boxes (which see). A 

 very beautiful practice is now in use to plant 

 them in early spring with Pansies, which re- 

 main in bloom until June, the time at which 

 the summer plants are ready to be planted to . 

 take their place. Vases are usually exposed 

 to the full force of the sun on the open lawn, 

 and, consequently, require a great deal of 

 watering to keep them in good condition. By 

 mulching the surface with moss during sum- 

 mer, evaporation will be checked and a great 

 deal of labor saved. 



Vauqueli'nia. A genus of Rosacem comprising 

 one species with saw-toothed leaves and pure 

 white flowers. It was first described by Dr. 

 Torrey as Spireea Calif omica, but was referred 

 to its right genus by Mr. Watson. It is a na- 

 tive of Mexico, Arizona, etc.

 greatly Interested in Algce. Nat. Ord. Ooode- 

 niacecB. 



A genus fit green-house, perennial herbs,

 naturalist, who edited the works of Vandelli 

 on Brazil. Nat. Ord. Amarillidacem. 



The Vellozias are like perennial Lilies, and 

 grow from two to ten feet high, having trunks 

 as large as a man's body, branching, and hav- 

 ing tufts of leaves on the top like the Yucca. 

 The flowers are large, white, blue or violet, 

 produced singly or on slender scapes from 

 the tips of the branches. They are showy 

 and attractive features in the mountain re- 

 gions of Brazil and Australia. Syn. Barbacenia. 



Velthei'mia. Named in honor of JF. A. Velt- 

 hewi, a German botanist. Nat. Ord. Liliacece. 

 Large-growing bulbs from the Cape of 

 Good Hope. The flowers are flesh-color and 

 of but little beauty, though of long duration. 

 V. viridifolia has beautiful, broad, shining, 

 green leaves, with undulated margins and a 

 flower scape one to two feet long. It is a 

 very interesting and showy species. The 

 bulbs rest the entire summer, and come into

 or plants may be readily raised from seeds- 

 sown in spring. It is the best of the genus- 

 and Well worthy of cultivation. 



Venose. Veiny ; having many branched veins. 



Ventila'go. From ventilo, to be exposed to the 

 wind, and ago, to drive away; in allusion to-
