38. PYROLIRION. - Leaves attenuated at both ends ; scape one-flowered ; germen sessile ; tube cylindrical, erect; limb campanulate with reflex points; fila- ments equal or alternately equal, suberect, patent ; anthers versatile ; style erect or reclining ? stigma trifid. 1. Aureum. Pl. 29. fig. 4. Spec. 400. Herb. Lindl. Pl. 23. fig. 3. Spec. Dombey Herb. Soc. Linn. A. aurea. Flor. Per. 3. 56. 286. A. tubiflora, L'Her. S. A. 10.{L'Her. S. A. 6.} Lil. Narc. Feuill. Obs. 3. 29. 26. A. Pe- ruviana. Ker. Lamark. Bulb beset with blind off- sets, scape a foot high, flower 4-4 1/4 inches long, golden, mouth of the tube scaled ; style scarcely exceeding the filaments. Dombey's specimen, which is L'Heritier's plant from Lima, has the flower more than four inches long. The peduncles in the plate of Flor. Per. are false, and not men- tioned in the description. It flowers in January and February in the cornfields of Peru at Lurin,

Surco, Magdalena, Lurizancho, and Chorillo, near Lima ; called Hamanco de Antibo. 2. Flammeum. - Flor. Per. 3. 56. 286. Lilio-narc. mon. coccin. Feuill. Obs. 3. 29. 21. Flower shorter, limb only two inches, fiery orange, faucial scales short, truncate, and crenate. In the cornfields of Chancay, near Huaura, and in the fields and on the hills of Conception in Chili. 3. Flavum. - Spec. Ruiz. Herb. Lamb. - Pyrol. aureum, fauce lævi. Bot. Reg. 20. 1724. Scape short ; flower 3 inches or less, pale golden ; tube smooth ; filaments much shorter than the style ; stigma deeply trifid. There is a specimen from Peru with the scape shorter than the flower, which is decidedly flavum ; two other spe- cimens of aureum are erroneously marked flavum. These three plants are very nearly allied, but as Ruiz distinctly describes the faucial scales of aureum and flammeum, the plant in which Dr. Lindley found none, must be the third species which Ruiz named, but did not describe. It also agrees with it and differs from aureum in the short scape, long style, and paler colour ; and disagrees with aureum in not having the circle of blind offsets described by Ruiz, which I find in an imported bulb of Pyrolirion, which has not flowered. The figures in the Flor. Per. are quite un- worthy of faith, but the descriptions of Ruiz appear to me singularly correct. The three species are probably dis- tinct ; aureum with larger golden flower, style little exceed- ing the filaments, and faucial scales longer; flammeum with smaller flowers, fiery orange, and crenate scales ; and flam- meum with paler flowers, longer style, and short scape. The filaments of flavum in Mr. Lambert's specimen are as nearly equal as possible.

4 ? Albicans. - Lil. Narc. monanthus flore albicante, tubo prælongo. Feuillet Obs. 3. 29. f. 20. Scapo tereti, virente, 8-unc. tubo 2-unc. 1 1/2 lin. lato ; limbo circiter 2-unc. laciniis acutis apice reflexo ; foliis 7-8-unc. 1 1/2 lineas latis, viridibus, acutis, canaliculatis. In valle Ylo intra montes Peruviæ, situ aridissimo. This plant, from Ylo in Peru, is
185
only known to us by Feuillet's description and bad plate, with a whitish tubular flower, and limb reflex at the point ; it agrees with no genus but Pyrolirion. There is no spathe in the figure. It is impossible to be quite certain that this plant may not be a Cooperia ; but both the leaves and reflex points of the limb seem to correspond with those of Pyrolirion. I have not possessed this genus long enough to be sure of its habits. It flowers before the full growth of the leaves in S. America in January and February, that is at and after midsummer, therefore the leafing of the plant is autumnal. As it had had leaves all the last summer at Spofforth, I left it dry through the winter and started it in the spring ; but, as it appears disposed to push more leaves this year in September, I apprehend that its proper season of rest will be the spring and fore-part of the summer.
