Upper internodes 30-35 mm. in length. Stems large, laterals sometimes mm. in diameter, coarse, mostly erect, occasionally lax; frequently purple, but sometimes green. Fruits variable in size 2^6 cm. long; 1-6 seeded, mostly 3-4 seeded. Shells variable, usually moderately thick with only slightly raised venation; sometimes thin with prominent venation and beaked; constrictions between the seeds slight, occasionally more evident. Seeds variable, spherical or elongated, usually red or purple-black, sometimes pink or flesh; gm., usually about gm.; germinating immediately upon maturity. Highly susceptible to cercospora leaf spot. Beattie (9) lists the following varieties grown commercially in the. Figure 23.—An n + 1 order, cotyledonary lateral branch of one form of Valencia. The n +1 branch produces n + 2 reproductives at its lowest nodes, then several n + 2 vegetatives, finally the upper nodes produce n-\- 2 reproductives. All the nodes of the » -f- 2 vegetatives bear n + 3 reproductives which terminate the branching Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Arant, F.
