or a spot below the middle of each petal ; and where this 

 is not evident, the general color of the petal becomes darker 

 at that place. This constant tendency must be an indica- 

 tion of some remarkable physiological peculiarity, although 

 we cannot explain its nature, and such indications are by 

 no means to be overlooked in determining the limits of ge- 

 nera. {Bot. Reg:, Nov.)

^RISTOLOCHIA 



gigas Lindl. Giant Birtliwort. A greeiihousr^ climber; growing 10 feet liigh ; with 

 white and purple flowers ; appearing in sunnmer ; a native of Guatemala ; increased by 

 cutting ; cultivated in loam, heath mould and sand. Bot. Reg., 184'2, t. 60. 



This immensely large and fine species forms one of the 

 most " striking objects" of the greenhouse, either trained 

 up the rafters or on a trellis. The flowers are at least ten 

 inches in diameter, and beautifully spotted with purple, 

 deepening to a dark purple in the centre. The foliage is 

 cordate, acuminate, sub-pubescent, and not very large. This 

 species was first exhibited at the garden of the London 

 Horticultural Society, at its shows in June and July, and 

 excited the astonishment of the visiters, from the great size 

 of its flowers, and the smallness of the plant, which was 

 growing in a pot, the branches trained to a trellis. It was 

 sent home from Guatemala by Mr. Hartweg, and flowered 

 for the first time last summer. It strikes readily from cut- 

 tings, and, if potted in a mixture of heath mould, loam and 

 sand, it will grow and flower freely. {Bot. Reg., Nov.)

/NDIGOFERA. 



dosua De Cand. The Dosua indigo. A greenhouse plant ; growing four or five feet high ; 

 with rose-colored flowers ; appearing in May ; a native of East Indies : increased by 

 cuttings and seeds ; cultivated in good garden soil. Bot. Reg., 1842, t 57. 



" Pretty when in flower," forming a straggling bush, 

 whose bright, deep rose-colored blossoms, are highly orna- 

 mental. Stem shrubby, with 8-10 pinnate leaves, and ax- 

 illary spikes or clusters of deep rose-colored flowers, thickly 

 covering the stems, and contrasting agreeably with the deli- 

 cate foliage. It appears to be half-hardy, and flowers freely 

 in July and August, if turned out into the border. The 

 seeds were sent from the Botanical Garden of Saharunpur, 

 and presented to the Horticultural Society by the Directors 

 of the Eiast India Company. It grows freely from cuttings, 

 treated in the ordinary manner. {Bot. Reg., Oct.)
