ICOSANDRIA POLYGYNIA
ROSA. Schreb. gen. n. 863.
Calyx pitchered, five-cleft, fleshy, contracted in the neck.
Seeds numerous, hispid, affixed to the interior side of the calyx.

1. R. involucrata. R.
Subscandent, armed with strong stipulary, straight prickles. Flowers in subsessile fascicles. Bractes in form of a four or five leaved laciniate, inferior calyx.
     A native of Nepal and Bengal; it flowers about the beginning of the warm weather in February; its seed ripens in the rains. Stem and branches stout and ligneous, the latter often very long, subscandent, armed with strong, straight, stipulary prickles; young shoots villous. Leaves pinnate; common petiole villous, slightly armed, stem-clasping, base pinnatifid. Leaflets opposite, from five to eleven, oblong, serrate, villous underneath; the largest about an inch long, and half an inch broad. Flowers terminal, from one to many together, subsessile, large pure white, sweetly fragrant. Bractes four or five, surrounding the base of the germ, singly they are lanceolate, acuminate, with the lower margins deeply laciniate, and villous. Calyx villous; divisions entire, Corol single. Petals obcordate. Germ globular, villous.

2. R. centifolia. Willd. 2. 1071.
Germs ovate, with peduncles hispid. Stem hispid, and prickly. Petioles unarmed.
     Arab. Wurd.
     Pers. Gool.
     Hind, and Beng. Gulab.

3. R. chinensis. Willd. 2. 1078.
Germs obovate. Stem with remote, large prickles. Peduncles hispid. Petioles almost unarmed. Leaflets about five, broad-lanceolate, serrate, having both sides smooth. Divisions of the calyx downy on the inside.
     Beng. Kanta, or Kath-Gulab.
     A native of China. Flowering time the cold season. It agrees so well with Linnaeus's description of Rosa Indica, as to induce me to think they are the same.

4. R. glandulifera. R. [Rosa moschata Mill. Dict.]
Germs oblong, shrubby, subscandent, armed. All the tender parts ciliate, with glutinous, headed glands. Leaflets from five to seven, ovate, doubly-serrate. Segments of the calyx sub-ensiform, finely pinnatifid. Flowers terminal in large corymbiform panicles.
     Beng. Swet, or Sheooti gulab.
     Found in gardens throughout India, where it is commonly called the white rose; its flowers being double, fragrant and white, like the white rose (R. alba,) of Europe. Where this plant is indigenous is uncertain, probably China, as I know it has been brought from thence to the Botanic garden at Calcutta. It blossoms all the year round; but chiefly during the cold season.

5. R. semperflorens. Willd. 2. 1078.
Germ globular, smooth; peduncles hispid. Stems and petioles aculeate. Leaves quinate, pinnate; leaflets Ianceolate, serrate Calycine segments, subentire, woolly on the inside.
     A small, very ramous species, a native of China. In Bengal it is in constant flower, but most profusely during the cool season.

6. R. pubescens. R. [= Rosa brunonii Lindl.]
Germs globular. All the tender parts tomentose, and glanduliferous. Segments of the calyx entire; stems, branches and petioles armed. Leaflets seven, lanceolar, serrate.
     A native of the mountains north of Rohilcund.

7. R. recurva. R.
Sub-scandent, well armed, with strong recurved prickles. Leaflets from five to nine, ovate-lanceolate, acutely serrate, smooth. Stipules subulate; petioles armed.
     This stout, straggling, recurved, powerfully armed shrub is a native of Nepal; from thence it was sent by Dr. Buchanan to the Botanic garden at Calcutta, where it has now been ten years and has not yet blossomed. Dr. Buchanan however ascertained the genus in Nepal, where it blossoms freely.

8. R. diffusa. R.
Stems and branches weak, diffuse, armed with strong, recurved prickles in stipulary pairs. Leaflets five, ovate-oblong, villous; stipules pectinate.
     This distinct species is readily known by its weak, diffuse and procumbent, very long, almost simple branches, which often rest on the ground; it is supposed to be a native of China, as it was brought from Canton to the Botanic garden at Calcutta.

9. R. microphylla. R. [= Rosa roxburghii Sweet]
Suffruticose, armed with straight pairs of stipulary prickles only. Leaflets seven or nine, minute, oval, finely and acutely serrulate; stipules ensiform, entire.
     Chin. Hoi-tong-hong.
     Introduced from Canton into the Botanic garden at Calcutta.

10. R. triphylla. R. [= Rosa anemonaeflora Fortune ex Lindl.]
Scandent, armed. Leaves ternate; leaflets lanceolate.
     From China this very extensive rambler was brought to the Botanic garden at Calcutta, previous to 1794, where it thrives luxuriantly, and is known to the Chinese gardeners in the garden by the name, Tsha-te-bay-fa.

11. R. inermis. R. [= Rosa banksiae Aiton]
Suffruticose, unarmed; leaves ternate and quinate-pinnate; leaflets lanceolate, serrate, smooth.
     Of this very elegant small plant we have two varieties from China: one with double white flowers, called by the Chinese, Po-mou-he-wong; the other with double yellow flowers, Wong-mour-he-wong.
