without water, as are also other woolly succulents, etc' The 

 absence of the conical points to the stigma of this species 

 would remove it from Kleiuia as characterised by most authors ; 

 its habit and capitiilum are, however, those of the peculiar 

 group of chiefly South African plants to which that name was 

 oriRinally applied." — {Bot. Mag., t. 00(>3.) 



Pentstemon- P.u,meri. A'nf. ord., Scrophulariacea?. Linn., 

 Didynamia Augiospermia. — Native of California. Flowers 

 creamy and rosy purple. " Mr. W. Thompson, of Ipswich, 

 flowered it in August of the present year from American seeds ; 

 he informs me that it attains a height of 8 to 1 feet, from 

 which, at Watson's attributing to it a stature of 2 to 5 feet, I 

 judge that it must be altogether the grandest and most beauti- 

 ful known species of the genus. Though coming from so 

 Bouthern a latitude, 82 --42' N., it appears to be quite hardy."

SA.xiFiU(ii KoTscHYi. Xat. ord., Saxifragacete. Linn., Dec- 

 andria Digynia. — Native of Asia Minor. Flowers yellow, 

 calyces red-tipped. " This is one of the group of Saxifrages 

 that forms dense hard cushion-shaped masses on the moun- 

 tains of the South of Europe and Western Asia, where they 

 are exposed to great summer heat and winter cold, without the 

 humidity of a more nortliern or western climate. They are 

 conseijuently verj- difficult to cultivate in England ; and where 

 they have succeeded they never form the luxuriant masses that 

 they do in the Mediterranean region. S. Kotschyi is a native 

 of precipitous rocks in the Cilician Taurus, at an elevation of 

 6 9000 feet, as also of the mountains of Armenia and Cataonia, 

 all in Asia Minor, where it was discovered by Aueher Eloi, 

 the French explorer on the Thessalian Olympus. It flowered 

 in the Royal Gardens (where it has been in cultivation for a 

 good many years) in May, 1S73, and bears evidently imperfect 

 flowers, the petals being smaller than in the native specimens, 

 and the stamens and the stvles quite arrested in growth."—

Cf.lsia BETONic.-EFOLU. Wn<. orif., Scrophnlariaoea;. Linn., 

 Dilyuamia Angiospermia. — Native of N.W. Africa. Flowers 

 yellow and red. "A little-known plant, discovered by Des- 

 fontaines in fields in Algeria, subsequently in Tangiers by 

 Salzmann, and lastly by myself (in 18.39), on the top of a peak 

 in the fslaud of St. Jago, one of the Cape de Verd group, a 

 station very far removed from the above. It is remarkable 

 that it has not been detected in the Canary Islands. It is 

 closely allied to the widely-distributed C. cretica, L. (Tab. 

 nost. 91)1), which ranges from the Canary Islands to the East 

 Indies, differing in usually less divided leaves and long pedicels 

 of the flowers. 



"In Maroceo two varieties occur, one nearly glabrous, the 

 other woolly ; both are found in the valleys of the Greater 

 Atlas, ascending to .5000 feet, as also in fields on the plains ; 

 the lower leaves are sometimes pinnatifid throughout. The 

 specimen here figured was flowered by Mr. Niven of the Hull 

 Botanic Gardens, in August last, I believe from seeds procured 

 by Mr. Maw in Maroceo in 1H"1."— {Ibid., t. COCG.) 



Abistolochi.i TBicArDATA. Xal. ord., Aristoloehiacea?. Linn., 

 Gynandria Hexandria. — Native of Eastern Mexico. Flowers 

 crimson-stalked, tnbo creamy, purple-tailed. " It was dis- 

 covered by Ghiesbreght, an indefatigable explorer, and trans- 

 mitted by him to M. Verschaffelt, of Ghent, by whom it was 

 published, in 1800, with an excellent plate in the ' Illustration 

 Horticole.' H. tricaudata flowered in the stove at the Royal 

 Gardens in August last, on a plant received from Mr. Bull in 

 the previous year. It is said to recommend itself to the cul- 

 tivator from the negative quality of wanting the detestable 

 odour so prevalent amongst its congeners." — {Iliid., t. G007.) 



Crassci.a S,vxiFr.Ar,A. Nnt. ord., Crassulacerp. Linn., Pent- 

 andria Monogynia. — Native of South Africa. Flowers pale 

 flesh-coloured. " For this very singular and brilliantly- 

 coloured S. African plant the Royal Gardens are indebted to 

 Principal MacOwen, of Gill College, Somerset East, who trans- 

 mitted tubers of it from that district, which flowered in .June 

 of the present year. It would seem to have a wide South 

 African distribution, being found on mountain sides from the 

 extreme sonth-west, as on the Muysenberg Mountain, near 

 Simon's Bay, to Port Elizabeth and .\ll)any. The brilliant red 

 colouring of the under surface of the leaf is not a constant 

 character."— (/()M., t. 0008.) 



Tacsonia issionis.—" Raised by Mr. R. Anderson, gardener 

 at Sowerby House, Hull. The honour of introducing it to this 

 country helongi to Yarborough L. Greame, Esq., by whom 

 seeds were sent to England some few years since, and who in 

 a memorandam commanicated by Mr. Anderson, writes as 



follows concerning it : — ' I saw the Tacsonia growing in a deep 

 richly-wooded gorge, on the eastern slope of the Cordilleras, 

 between La Paz and Chulumani, in the north of Bolivia. It 

 seemed to like to climb to the end of a long branch, and then 

 hang in festoons, swayed backwards and forwards by the 

 breeze.' This description of its manner of growth is, we learn, 

 very accurate, since it supports itself by its tendrils till it 

 begins to flower, and then hangs loose, each branch having as 

 many as a dozen or fourteen flowers open in different stages of 

 development. We believe the plant is to be sent out by 

 Messrs. Backhouse & Son, of Yoxk."— [Florist and Pomolofjist,

THE EUCALYPTUS GLOBULUS AS AN 

 ANTI-FEVER TREE. 

 Ax the last meeting of the French Academy of Sciences an 

 interesting commuuieation was read from M. Gimbert, who 

 has been long engaged in collecting evidence concerning the 

 Australian tree. Eucalyptus globulus, the growth of which is 

 surprisingly rapid, attaining, besides, gigantic dimensions. 

 This plant, it now appears, possesses an extraordinary power 

 of destroying miasmatic influence in fever-stricken districts. 

 It has the singular property of absorbing ten times its weight 

 of water from the soil, and of emitting antiseptic camphorous 

 etHuvia. When sown in marshy ground it will dry it up in a 

 very short time. The English were the first to try it at the 

 Cape, and within two or three years they completely changed 

 the eliraateric condition of the uuhealthy parts of the colony. 

 A few years later its plantation was undertaken on a large 

 scale in various parts of Algeria. At Poudook, twenty miles 

 from Algiers, a farm situated on the banks of the Hamyze 

 was noted for its extremely pestilential air. In the spring of 

 1807 about thirteen thousand Eucalypti were planted there. 

 In July of the same year, the time wlieu the fever season used 

 to set in, not a single case occurred ; yet the trees were not more 

 than y feet high. Since then complete immunity from fever 

 has been maintained. In the neighbourhood of Constantia 

 the farm of Ben Machydln was in equally bad repute ; it was 

 covered with marshes both in winter and summer ; in five 

 years the whole ground was dried-up by fourteen thousand of 

 these trees, and farmers and children enjoy excellent health. 

 At the factory of the Gue de Coustantine, in three years, a 

 plantation of ihe Eucalyptus has transformed twelve acres of 

 marshy soil into a magniliccnt park, whence fever has com- 

 pletely disappeared. In the island of Cuba this and all other 

 paludean diseases are fast disappearing from all the unhealthy 

 districts where this tree has been introduced. A station house 

 at one of the ends of a railway viaduct in the department of 

 the Var was so pestilential that the officials could not bo kept 

 there longer than a year ; forty of these trees were planted, 

 and it is now as healthy as any other place on the line.^

WEEVILS. 



Yon ask for my mode of trapping these in the orchard 

 house. Having pressed down the soil in the pots to make it 

 level, I lay on it a cake of half-decomposed hay, taken from 

 the bottom of a heap of the mowings of the previous year. 

 Every morning I look to see where the leaves have been freshly 

 bitten. I have then only to turn over the grass and find the 

 weevil below. When the grass is not consoUdated it is some- 

 times tedious to find the offender, as his colour is the same as 

 old grass. I allow this latter to remain as a top-dressing ; 

 richer material may be added above. Figs are especially fond 

 of rooting into the decaying grass. — G. S.

 PANT.ILOONS. 



Tnis is a term applied by the old florists of two centuries 

 ago to a form of the Hose-in-Hose, " having green leaves about 

 their blossoms, which are sometimes variegated with the same 

 colours as the flowers they encompass." This in modern lan- 

 guage signiUes that the calyx is not an exact fac-simile of the 

 corolla, as in the Iloso-in-IIose, but is enlarged, so as to be- 

 come funnel-shaped, and while partaking of the colour of the 

 corolla, it is variegated with green stripes. Of these I have a 

 very large variety, ranging in colour from pale lemon yellow
