APPENDIX. 265 



On page 209, vol. i, under Opuntia brasiliensis, add to distribution: Peru. 



Insert: Opuntia brasiliensis gracilior Salm-Dyck was given by Forster (Handb. Cact. 

 500. 1846) as a synonym of 0. brasiliensis minor. 



Also insert : Dr. Small has found this plant established after planting on shell mounds 

 and waste places in southern Florida. 



Add to illustrations: Goebel, Pflanz. Schild. i: f. 37, 38. 



On page 211, vol. i, under Ammophilae, substitute for characters of the series: 



Erect species, sometimes with a definite continuous trunk, often much branched, the joints 

 broad and flat, spiny or unarmed, the spines (when present) subulate or subulate-acicular, whitish, 

 gray or reddish, the large flowers yellow. 



The series now appears to be most nearly related to the Series Tortispinae (vol. i : 

 126) and may be placed to follow it as series 7a. Opuntia austrina Small, of southern 

 Florida, may be transferred from the Tortispinae to the Ammophilae. 



On page 211, vol. i, under Opuntia ammophila, insert: More recent collections of this 

 plant by Dr. Small, show that its range extends south to Cape Romano, Florida, and that 

 the definite trunk, at first taken as characteristic of it, is not always developed ; his living 

 plants from different stations show slight individual differences which do not appear to 

 be specific. This species has been erroneously referred by Dr. Griffiths (Bull. Torr. Club 

 46: 201) to Opuntia bartramii Rafinesque. 



On page 213, vol. i, insert: 



239a. Opuntia turgida Small, sp. nov. 



Plant erect, more or less diffusely branched, 0.5 meter tall or less, with fibrous roots; joints 

 elliptic to elHptic-obovate, 5 to 12 cm. long, thickish, deep green, sometimes slightly glaucous 

 when young; leaves subulate, 6 to 10 mm. long, spreading and more or less recurved, green, some- 

 times accompanied by fine bristles, but without spines; areoles scattered, often prominent and 

 densely bristly on the older joints; spines (as far as known) wanting; flowers often several on a joint; 

 ovary obovoid or obconic-obovoid, 2 to 2.5 cm. long, slightly tubercled; sepals green or purple- 

 tinged, the outer subulate to lanceolate, 4 to 10 mm. long, acute, the inner rhombic-ovate, fully 

 1.5 cm. long, stout-pointed; corolla bright yellow, 5.5 to 6.5 cm. wide; petals 10 to 12, about 3 cm. 

 long, broadly cuneate, abruptly narrowed, rounded or subtruncate at the apex, mucronate; anthers 

 2 mm. long; berry obovoid, 2 to 2.5 cm. long, greenish purple, even, broadly rounded at the base, 

 the umbilicus flat or a little depressed at the middle; seeds rather numerous, about 4 mm. in 

 diameter, somewhat turgid. 



Hammocks near Yulee and on the mainland along the Halifax River south of Daytona, 

 Florida. Type collected about five miles south of Daytona, in December 1919, by J. K 

 Small, preserved in the herbarium of the New York Botanical Garden. 



This spineless, small-jointed species is tentatively referred to the Series Ammophilae 

 on account of its fruit characters and erect habit. A plant sent from Kew to the New 

 York Botanical Garden in 1902, under an unpublished name, very closely resembles this 

 species. 



On page 214, vol. i, insert the following: 



Opuntia napolea, offered for sale by Grassner (Monatsschr. Kakteenk. February 1920) 

 we have not seen. 



The name Opuntia spirocentra Engelmann and Bigelow (Haage, Verz. Cact. 30), 

 found in the Index Kewensis, we have not been able to verify. As the name is credited to 

 Engelmann and Bigelow and the habitat of the plant is said to be New Mexico it is doubtless 

 an error and probably was intended for 0. macrocentra. 



Opuntia todari (Haage and Schmidt, Haupt-Verz. 230. 1912) is known only in the trade.
