. Carnegie Institution of Washington publication. APPENDIX. 225 Figure 300 shows a joint collected by Dr. Rose at Cuenca, Ecuador, in 1918. 207 a. Opuntia dobbieana sp. nov. (See page 187, ante.) Usually low and bushy, forming dense thickets, but sometimes tall and then 3 to 4 meters high; joints orbicular to short-oblong or obovate, i to dm. long, pale green in color, very spiny; leaves minute, i to 2 mm. long, green, spreading; areoles small, closely set; spines white, 5 to 12, usually acicular but on old joints subulate, i to 3 dm. long, accompanied by 2 to 4 reflexed hairs from the lower side of the areole; flower, including ovary, 5 to 6 cm. long; petals chocolate-colored, oblong, 2 cm. long; filaments and style pinkish; stigma-lobes dull green; overy strongly tubercled, leafy, very spiny, especially towards the top; fruit juicy, red, at first spiny, 3 to 5 cm. long. Common in dry places from Huigra to Sibambe, Province of Chimborazo, Ecuador- Collected by J. N. Rose and George Rose, August to November 1918, at Huigra (No. 22201, type); at Sibambe, August 29 (No. 22434). This species, on account of its white spines, is referred to the Streptacanthae, although it usually is more bushy than these species generally are. So far as we could learn, the fruit is not used by the Ecuadoreans; the plant was never seen cultivated, and there is every reason to believe it is native to Ecuador. The species is named for John Dobbie, general manager of the Guayaquil and Quito Railway, whose courtesies and assistance added greatly to the success of Dr. Rose's visit to Ecuador in 1918. Figures 301 and 302 (the latter at the bottom of this page) are from photographs of the type plant, taken by George 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 Carnegie Institution of Washington.
