whether the leaves are alternate or opposite. The leaves are 

 said to be ovate in the diagnosis, and in the description obovate. 



Stiff Aizoon. Shrub decumbent. 



10 A. FRUTICOSUM (Lin. fil. suppl. 1. c.) stem shrubby, erect, 

 glabrous, stiff; leaves lanceolate, glaucous, attenuated at the 

 base; flowers sessile. Tj . D. G. Native of the Cape of Good 

 Hope. Thunb. fl. cap. 410. The description does not mention 

 whether the leaves are alternate or opposite. 



Shrubby Aizoon. Shrub 1 foot. 



1 1 A. SECU'NDUM (Lin. fil. suppl. 1. c.) stem herbaceous, hairy, 

 decumbent ; leaves ovate, acute, rather petiolate, beset with silky 

 villi ; flowers sessile, secund, axillary. Native of the Cape of 

 Good Hope. Thunb. fl. cap. 409. Leaves a line long ; in the 

 diagnosis they are said to be ovate, but in the description ob- 

 ovate. 



/Secunrf-flowered Aizoon. PI. decumbent. 



Cult. This genus of succulent plants is not worth growing 

 except in botanical gardens. The culture, treatment, and pro- 

 pagation recommended for the genus Mesembrylmthemum will 

 answer well for the species of Aizoon also. 



V. MI'LTUS (from /uiXroe, miltos, vermilion ; in reference to 

 the deep red colour of the whole plant). Lour. coch. p. 302. 

 D. C. prod. 3. p. 454. 



LIN. SYST. Icosdndria, Pentagynia. Calyx 5-parted, per- 

 manent, spreading, coloured. Petals wanting. Stamens 12, in- 

 serted in the bottom of the calyx ; anthers standing. Ovarium. 

 roundish. Style wanting ; stigmss 5, linear. Capsules 5, con- 

 nate, each containing one seed. A prostrate shrub, with ob- 

 long, opposite, crowded leaves ; and crowded lateral flowers.

 spreading calyx, and in the capsules being 1-seeded.

LIN. SYST. Dodecdndria, Pentagynia. Calyx 5-parted, con- 

 niving, permanent, coloured inside, with 3 of the sepals exterior, 

 and the other 2 interior. Petals strap-formed, 2-4-cleft at the 

 apex, from 5 to 20 in number, shorter than the calyx. Stamens 

 about 15. Ovarium distinct. Style very short or wanting; 

 stigmas 5. Capsule covered by the calyx, 5-valved, 5-celled. 

 Seeds numerous, minute, hanging by a very long involute funicle 

 each. Embryo spiral. Branched procumbent tomentose herbs, 

 with alternate leaves or in unequal pairs. Flowers axillary, 

 almost sessile. The plants have the habit of Aizoon, but the 

 embryo is that of Caryophylleee.

 1 -flowered, axillary. Q. H. Native of Spain, Sardinia, North 

 America, north of Africa, Archipelago, and Senegal, Egypt, Asia,

 tomentum, prostrate, suffruticose ; leaves orbicular, flat, on very 

 short petioles ; flowers axillary, nearly sessile. Tj . G. Native 

 of the East Indies. Vahl. symb. 3. p. 64. Pluk. amalth. t. 306.

 diffuse ; leaves nearly orbicular, in whorles, petiolate ; flowers 

 axillary, capitate. Tj . G. Native of Arabia Felix, about Dahi, 

 in inundated places. Vahl. symb. 3. p. 64. Plenckia setiflora, 

 Ralin. 1. c. Petals numerous, linear, yellow, divided into 3-4

 Glinus lotoides ex Vahl. 



Bristle-flowered Glinus. Shrub diffuse. 



f Species not sufficiently knonin. 



4 G. ? TRIANTHEMOIDES (Roth, nov. spec. 231.) plant pros- 

 trate, glabrous ; leaves obovate, wedge-shaped, rounded, mucro- 

 nate ; panicles loose, terete, opposite the leaves. Native of the 

 East Indies. This plant differs from Glmus in the petals being 

 wanting. It is therefore perhaps a species of Miltus; but this 

 is still doubtful because the number of the seeds are unknown. 



Trianthema-like Glinus. PI. prostrate. 



Cult. These plants will grow well in a mixture of sand, peat, 

 and loam ; and young cuttings of the shrubby kinds will strike 

 root readily in the same kind of soil. The seeds of the annual 

 species had better be reared on the hot-bed, and when the plants 

 are of a sufficient size, they should be planted out into a warm 

 damp situation.

ORDER CXV. NITRARIA'CE^E (this order only contains 

 the genus Nitraria). Lindl. introd. nat. syst. p. 163. 



Calyx inferior, 5-toothed, fleshy. Corolla of 5 petals, which 

 arise from the calyx, inflexed, valvular in aestivation. Stamens 

 3 times the number of the petals, perigynous ; anthers innate, 

 with 2 oblique, longitudinal lines of dehiscence. Ovarium su- 

 perior, 3 or more celled, with a continuous fleshy style, at the 

 apex of which are as many stigmatic lines as there are cells in 

 the fruit ; ovula pendulous, by means of a long funicle. Fruit 

 drupaceous, opening by 3 or 6 valves. Seeds solitary, without
