- Revue horticole. Paris: Librairie Agricole de la Maison rustique 1829-1974. Anne 1883: Page 372 http://www.biodiversitylibrary.org/item/196490 Begonia Martiana gracilis, one of our subscribers, M. Lamare, a horticulturist at Bayeux (Calvados), who cultivates an extensive culture of the tuberous Begonias, notably of B. Martiana gracilis, informs us that this plant does not yield seeds: In spite of the most assiduous care and careful fertilization, both in the greenhouse and in the ground, I have not been able this year to harvest a single seed from more than a hundred fertilizations. The petals fall, it is true, but soon it is the ovaries which, moreover, never contain seeds. The fact of which M. Lamare speaks may seem all the more singular, as the Begonia diversifolia, which is excessively fecund brings forth, and abundantly produces seeds. Is this sterility of B. Martiana gracilis, by M. Lamare, an exception, a fact resulting from particular conditions? This plant, which was discovered in Mexico near San Luis de Potosi, belongs to the group of tuberous Begonias, and is situated near the Begonia diversifolia, of which it appears to be only a more compact form, of which it has all the characteristics. However, from an ornamental point of view, it has the great advantage of being much more compact, and by its many ramifications, forms a strong bush, as shown in Fig. 66. Its principal characteristics are the following: Growth and appearance of Begonia diversifolia, but has much more ramifications starting from the base of the plant and is strictly built. Stems and branches succulent, glabrous, shiny, bark of a pale green herbaceous. Axillary branches usually born in groups. Leaves thick, fleshy, strongly inequilateral, green, glossy and varnished on both sides. Flowers large, about 5 centimeters in diameter, of a dark pink dark, or even wine red; the male has four thick, very inequal divisions; the two external ones larger, broadly rounded, and shortly dentate; the two very small, elliptic, obovate internal. Stamina numerous, gathered in the center of the flower in a subspheric mass. Female flowers suborbicular, with four subdivided divisions, the two extreme exteriors, the three internals largely obovate, rounded, often unequal, entire or hardly very shortly dentate; irregular stigmas, contour, of a greenish yellow; ovary unevenly triangular. B. Martiana gracilis is grown in a temperate greenhouse near glass. Its culture and its multiplication are made like those of the Begonia diversifolia. Like this one too, it is multiplied by its tubercles, which are very large, and by the aerial bulbils which it produces in very large quantities, a character which, is also like B. diversifolia. Plant under good, well-ventilated conditions, with sun, this Begonia becomes a huge compact bush, which reaches 1 meter or more in height and whose flowering is interrupted only by the frosts. Heavy watering is very favorable. E. A. CARRIERE.
