WELFIA (named in honour of the Royal Family

(two species) of stove, unarmed Palms, natives of Central 
America. Flowers pale yellowish-white, rather large; 
spathes two, deciduous; spadices thick, pendulous. Fruit 
dark violet, oblong, compressed, 2in. long. Leaves 
terminal, pinnatisect, on rather flat, short petioles; seg- 
ments much narrowed at base, entire or cut at apex.

WELL. A Well is not a desirable source for pro- 
euring water to give plants, as the water is invariably 
colder than the temperature and the soil in which the 
U SC are situated. If, however, there is no other efficient 
st ply, a quantity should be drawn or pumped up some 
time previous to being required for use, and meanwhile 
allowed to stand in an open tank. Well-water is also, 
as a rule, harder than rain-water, and is, consequently, 
not so well suited for administering to plants. See also 
Water.

WELWITSCHIA (named in honour of Dr. Frederic 
Welwitsch, 1806-1872, a celebrated botanical traveller). 
Syn. Tumboa. ORD. Cé e A monotypic genus. The 
species is one of the most remarkable productions of the 
vegetable kingdom. It is found growing in arid places in 
tropical and South-western Africa, where rain rarely falls. 
The two leaves were at first described as being simply 
persistent cotyledons enormously-developed, but such is 
not the case; the two cotyledons last for some time, and 
then the true leaves appear. Although W. mirabilis “was

first made known in Europe by Dr. Welwitsch, it appears 
to have been first discovered by Mr. C. J. Anderson, an 
eminent African traveller. This wonderful plant has 
been introduced into the Royal Gardens, Kew; but we 
do not know if it yet exists in any other establishment. 
It will probably prove very difficult to cultivate, on 
account of the impossibility of imitating the natural 
conditions under which it flourishes. It appears to us 
that the most probable method of succeeding with it 
would be to inclose a space within brick walls to a 
height of about 3ft. from the earth. This should be 
filled up, to a height of about 16in. or 18in., with a very 
light, porous soil, such as a mixture of light, sandy loam 
and broken bricks, in the proportion of two parts of the 
former to one of the latter. Above this the space should 
be filled in with sand and brick rubbish, mixed with a 
little sandy loam—about a tenth part of the latter, just 
to help to bind it. If planted in this way, the long, 
descending roots would penetrate into the lower soil, 
and derive sufficient nourishment and water from it, 
as the water would ascend into the lower stratum from 
the earth by capillary attraction, whilst the upper 
stratum being dry would prevent the plant from rotting. 
It should be fully exposed to the sun, and no water 
given it, though at evening a slight syringing over th 
leaves and crown would probably be beneficial, as this 
would in some way approach the dews to which it is 
subjected in its native country. The temperature should 
not be allowed to get below 50deg.” (N. E. Brown). 
W. mirabilis (wonderful). /f. solitary, contained within the 
scales of the young cones; cones scarlet, small, erect, at length 
oblong, in stout, dichotomously branched es, springing from 
near the insertion of the leaves. J. two, from deep grooves in 
the circumference of the trunk, 6ft. or more in length, quite 
flat, linear, very leathery, splitting with age into innumerable 
thongs, that lie curling on the surface of the soil. Trunk 
obconical, about 2ft. long, rising a few inches only above the 
soil, with the appearance of a flat, two-lobed, dep mass, 
sometimes 14ft. in circumference; when fully grown, it is dark 
brown, hard, and cracked, like the burnt crust of a loaf of 
bread; the lower part forming a stout tap-root, buried in the 
soil, and branching downwards at the end. 1862 and 1878. 
The plant is said to last a century. (B. M. 5368-9; T. L. S.

Garden at Hanover) Orn. Rubiacee. A genus com-

the corolla lobes. Leaves opposite or ternately whorled ; 
stipules entire or bifid. For culture of the two best-known 
species, see Wangueria. Both are stove trees. dd
