APPENDIX. 221 



terete, slightly spirally twisted; flowers usually several on a joint, conspicuous; sepals subulate to 

 lanceolate, acute; corolla yellow, 7 to 9 cm. wide; petals numerous, the inner ones broadly obovate 

 to flabellate, erose at the broad minutely mucronate apex; berries clavate, 5 to 6.5 cm. long, 

 red or reddish purple, many-seeded; seeds about 5 mm. in diameter. 



Type locality: Twelve miles west of Gainesville, Florida. 



Distribution: Pinelands, northern peninsular Florida. 



It was first observed by Dr. Small near Gainesville, Florida, in 191 7, and plants were 

 taken to Mr. Charles Deering's cactus garden at Buena Vista, Miami, where it has grown 

 luxuriantly, flowering and fruiting freely alongside of 0. poUardii which it resembles in 

 habit, but differs from in its long clavate berries and more numerous petals. 



Figure 290 shows joints of the plant; figure 291 shows its fruit. 

 127 a. Opuntia macateei sp. nov. (Seepage 133, ante.) 



Small prostrate plant; joints 2.5 to 6 cm. long, orbicular to obovate, glabrous, dull green, in

 longer ones up to 2.5 cm. long; flowers, including the ovary, 8 to 10 cm. long, 7 to 8 cm. broad,

 Collected by W. L. MacAtee at Rockport, Texas, December 28, 1910 (No. 1992).

Sometimes spreading and bushy,

 spiny; joints obovate, 2 to 4 dm. long, 

 bright green when young, or sometimes 

 slightly glaucous, grayish green in age; 

 leaves subulate, small, reddish at top; 

 spines at first 2 to 5, but in age 10 or 

 more, when young reddish or pinkish 

 at base and paler above, soon gray 

 throughout, unequal, subulate, 4 cm. 

 long or less ; flowers at first yellow but 

 soon orange to brick-red, rather large, 5 

 to 6 cm. long; petals few, about 10, ob- 

 long, retuse; filaments and style red- 

 dish; stigma-lobes pale green; fruit 

 obovate to oblong, 4 to 5 cm. long,

 pressed umbilicus. 



Collected at San Antonio, Prov- 

 ince of Quito, Ecuador, by J. N. 

 Rose and George Rose, October 29, 

 1918 (No. 23559). 



This plant was first collected 

 for us by Ludovic Soderstrom of 

 Quito, at the request of the Presi- 

 dent of the Central and South Amer- 

 ican Cable Company. Although 

 great care was taken in shipping the plants they all died in transit. In 191 8 Dr. Rose 

 visited Mr. Soderstrom's locality and collected herbarium, living, and formalin material 

 which has enabled us to describe the plant fully. The illustration here used was made 

 at the same time. 



Figure 294 is from a photograph of the type plant taken by George Rose.
