- No better example of carnivorous plants could be taken than Dionæa muscipula, or to use the common name, Venus’s Fly-trap. It is a species that is indigenous to North Carolina and the adjacent parts of South Carolina, affecting sandy bogs in the pine forests from April to June, and a representative of the Droscraceæ, or Sundew Family. One cannot fail after once seeing it of becoming impressed with its peculiar characteristics. It is a smooth perennial herb with tufted radical leaves on broadly-winged, spatulate stems, the limb orbicular, notched at both ends, and fringed on the margins with strong bristles. From the centre of the rosette of leaves proceeds at the proper time a scape or leafless stalk which terminates in an umbel-like cyme of from eight to ten white bracted flowers, each flower being one inch in diameter. The roots are small and consist of two branches each an inch in length springing from a bulbous enlargement. Like an epiphytic orchid, these plants can be grown in well-drained damp moss without any soil, thus showing that the roots probably serve for the absorption of water solely. Three minute pointed processes or filaments, placed triangularly, project from the upper surface of each lobe of the bi-lobed leaf, although cases are observed where four and even ten filaments are found. These filaments are remarkable for their extreme sensitiveness to touch, as shown not only by their own movement, but by that of the lobes also. Sharp, rigid projections, diminutive spikes as it were, stand out from the leaf-margins, each of which being entered by a bundle of spiral vessels. They are so arranged that when the lobes close they interlock like the teeth of an old-fashioned rat-trap. That considerable strength may be had, the mid-rib of the leaf, on the lower side, is quite largely developed. 596 visites
- Growing in poor peaty soil, and sometimes along the borders of ponds where nothing else can grow, certain low herbaceous plants, called Droseras, abound. So small and apparently insignificant are they, that to the ordinary observer they are almost unnoticed. But they have peculiarities of structure and nature that readily distinguish them. Scattered thickly over their leaves are reddish bristles or tentacles, each surmounted by a gland, from which an extremely viscid fluid, sparkling in the sunlight like dew, exudes in transparent drops. Hence the common name of Sundew by which the half-dozen species found in the United States east of the Mississippi River are known. A one-sided raceme, whose flowers open only when the sun shines, crowns a smooth scape, which is devoid of tentacles. Drosera rotundifolia, our commonest species, has a wide range, being indigenous to both Europe and America. In the United States it extends from New England to Florida and westward, and is occasionally associated with Drosera longifolia, a form with long strap-shaped leaves, but whose distribution is mostly restricted to maritime regions, from Massachusetts to Florida. 608 visites
- In the wet season they push out new shoots, from which grow rapidly wands three or four feet long, clothed with box-like leaves, and afterward with numerous pendulous flowers. These are elegant in shape and richly colored. They are urn-shaped, with five ribs running the whole length of the corolla, and their color is bright crimson with deeper colored V-shaped veins, as shown in the illustration of the flowers of almost natural size. They remain fresh upon the plant for several weeks. The beautiful appearance of a well grown specimen when in flower may be seen from the accompanying sketch of the specimen at Kew, which was at its best in July, and remained in bloom until the middle of September. 692 visites
- This is one of five species of Himalayan plants which, until recently, were included in the genus vaccinium. The new name for them is ugly enough to make one wish that they were vacciniums still. Pentapterygium serpens is the most beautiful of the lot, and, so far as I know, this and P. rugosum are the only species in cultivation in England. The former was collected in the Himalayas about ten years ago by Captain Elwes, who forwarded it to Kew, where it grows and flowers freely under the same treatment as suits Cape heaths. 720 visites

- Mother-Aphis and Her Army of Children on Tube Whilst engaged some few years ago in the study of the species that affects the blossoms of one of our gourds—the Cucurbita ovifera of botanists—certain phenomena were observed, which promised an easy and speedy solution of the problem. Gathered in compact masses, like companies of soldiery preparing for a foray, hundreds of aphides were seen, busily feeding, all over the flowers. There were old and young, not an indiscriminate mingling of ages and sizes, but an orderly arrangement of families, each family preceded by its own appropriate head. First came the very young of each family, only to be followed by those that were older, leaving the oldest of all to lead up the rear. 928 visites

- The use of Oyle of Violets. Oyle of Violets, Cammomile, Lillies, Elder flowers, Cowslips, Rue, Wormwood, and Mint, are made after the same sort; Oyle of Violets, if it be rubbed about the Tempels of the head, doth remove the extream heat, asswageth the head Ache, provoketh sleep, and moistneth the braine; it is good against melancholly, dullnesse, and heavinesse of the spirits, and against swellings, and soares that be over-hot. 997 visites

- Take Damask Roses, clip off the white of them, and take six ounces of them to every pint of faire water, first well boyled and scummed, let them stand so as abovesaid, twelve hours, as you doe in the Syrupe of Violets, wringing out the Roses and putting in new eight times, then wringing out the last put in onely the juice of four ounces of Roses, so make it up as before, if you will put in Rubarb, take to every two drams, slice it, string it on a thred, hang it within the pot after the first shifting, and let it infuse within your Roses: Some use to boyle the Rubarb in the Syrupe, but it is dangerous, the Syrupe purgeth Choller and Melancholly. 1005 visites
