This species has been sent to us re- peatedly from Oaxaca, Mexico, by Dr. B. P. Reko and it has been named in his honor; we have selected as the type his specimen of 1921, which flowered in Washington. This is a remarkable species, being the only one we know, except the follow- ing, which has the characters of watery tubercles, a hooked spine, and brown seeds, but some plants give out a very diluted milk and have no hooked spines. Dr. Reko sent us a single plant in April 1922, which was about 12 cm. long and short-clavate; the central spines were mostly 4, but sometimes 5, and none of them hooked. In this specimen we obtained a diluted milky juice from the upper tubercles while the lower ones are entirely devoid of milk. It flowered in April 1923 and seemed to be referable here. Figure 149 shows a plant sent by Dr. B. P. Reko from Oaxaca, Mexico, in 1919; figure 155a shows the plant collected by Dr. Reko in 1922, referred to Fig. 155a.—Neomammillaria rekoi. 108. Neomammillaria solisii sp. nov. Simple, globular or nearly so, 5 to 7 cm. in diameter, green or becoming purplish; tubercles 8 mm. long, terete in section, a little narrow towards the tip and thus separated above from the ad- joining tubercles, their axils without wool even when quite young, and usually with i to many bristles; radial spines about 10 to 20, spreading, 6 to 7 mm. long, white, bristle-like; central spines 3 or 4, a little stouter than the radials, becoming brown, one of them strongly hooked (sometimes 2 cm. long). Collected by Octavio Soils in Cerro de Buenavista de Cuellar, Guerrero, Mexico, in 1920 (No. 5) and
