PAXTON'S FLOWEB GAKDEN. 



Warrea bidentata. Linclley {alias W. Lindeniana, Hen- 

 frey) . A handsome terrestrial Orchid from New Granada, with 

 the habit of Warrea tricolor. Flowers pale cream-colour, with 

 a purple lip. Introduced by Mr. Rucker before 1844. (Fig. 46, 

 the lip magnified.) 



This well-marked species was originally described in the Botanical Register for 

 1844, at p. 76 of the miscellaneous matter. It has already been reproduced in the 

 Gardener's Magazine of Botany, p. 177, under the new name of W. Lindeniana. 

 It is not a native of Peru, as is stated in that work, but was foimd by Mr. Linden " on 

 the ground in the thick forests at the foot of the peak of Tolima, at the height of 

 4,000 feet," as is stated in the Orchidacew Lindeniana, No. 96. It is said to have 

 some pink in its flowers when wild, but that colour has not yet been observed in 

 cultivation. The form of the lip, which is remarkable, is shown in the annexed cut. 



Adiantum Williamsii. This Adiantum is a native of Peru, where it is said to 

 be found at an elevation of 12,000 feet, whence Mr. B. S. Williams received it. From 

 its general appearance it is evidently nearly allied to A. chilense, but it is of larger 

 growth than that species. Amongst the great number of ferns that have been intro- 

 duced of late years it is somewhat difficult to select the best, but, so far as general 

 usefulness goes, there can be no question that the kinds such as this, which will succeed 

 with greenhouse treatment, are much to be preferred to the more tender stove species. 

 It was awarded a first-class certificate by the Floral Committee of the Royal Horti- 

 cultural Society, South Kensington, May 2nd, 1877, and was also exhibited by Mr. 

 Williams at the provincial show of the Society held at Preston in the summer of 

 1878. 



Fronds tripinnate, triangular, membranaceous, bright green, glabrous ; pinna? ovate, distant ; pinnules sub- 

 rotund, that is, cut straight across the base with the pedicel nearly central, rarely towards the apex, slightly trapezi- 

 form, occasionally provided slightly at the angles so that the basal line is concave, the margin entire or very slightly 

 divided into 3 — 4 lobes, crenately notched between the sori, the sterile portions with an erose diaphanous margin; 

 sori 8—10 elongate reniform, or lunate, occupying the whole of the semicircular outer edge; indusium rugose mem- 

 branous, pale green, entire ; stipes castaneous, semiterete, and, as well as the slender rachides, smooth and glossy ; 

 caudex slowly creeping.— Gardener's Chronicle, N.S., vol. x., p. 45, with Fig. 



vEchmea Veitchii. Discovered in both New Granada and the United States of 

 Colombia in 1874, by the collectors Wallis and Shuttleworth. It appears to be nearly 

 allied to M. Maria? Reginse of Wentland. It is a handsome species, requiring a stove 

 temperature, and will succeed with the same treatment, as to soil, moisture, air, and shade, 

 during very bright weather, that most of the other kinds need. Even when not in flower its 

 finely-curved leaves give to it an elegant appearance, which is still further enhanced by its 

 stately erect flower-spike when in bloom. 



Leaves twelve to fifteen, forming a dense basal rosette, horny in texture, reaching a length of twelve to fifteen 

 inches, and a breadth of under two inches above the middle, so deeply channelled that they are semicircular in horizontal 

 section in the lower half, bright green, and quite naked all down the face, thinly white all down the back, without any 

 transverse bands, deltoid-cuspidate at the point, the edge bordered all down with close, small, erecto-patent, lanceolate, 

 brown teeth. Scape about a foot long, central, entirely hidden by the imbricated, lanceolate, adpressed, green, horny- 

 toothed bracts. Flowers in a dense oblong head, three or four inches long and under a couple of inches in diameter, 

 each subtended by a squarrose, bright scarlet, horny-toothed bract ; upper bracts without any flowers in their axils. 

 Ovary globose, a quarter of an inch long, the side nearest the axis much less convex than the outer one. Sepals lanceolate- 

 deltoid, under half an inch long, bright scarlet in the lower flowers of the head, white in upper ones, acute, but not 

 spine-tipped ; petals pale, Ungulate. Stamens about as long as the calyx, those opposite the petals furnished with a pair 

 of small scales at the base. — Botanical Magazine, 6329.
