near base and pressing against style; stamens and style included; ovary and flower- tube tubercled, 

 the former with short tubercles, the latter with oblong ones (sometimes 1.5 cm. long), each ending 

 in a depressed areole subtended by a minute scale; areoles bearing a tuft of brown felt and an 

 occasional brown bristle; fruit oblong in outline, 6 to 7 cm. long, 4 to 5.5 cm. in diameter, turgid, 

 nearly naked; rind green, thick, hard; seeds rounded above, cuneate at base, with a large lateral 

 depressed hilum. 



Fig. 258. — Neoabbottia paniculata. 



Type locality: Haiti. 



Distribution: Hispaniola. 



This plant was described by Plumier as follows : "Melocactus arborescens, tetragonus, 

 flore ex albido." This description was repeated by Tournefort, with the addition of a 

 single word, in 1719. Plumier's drawing of this plant was published long after his death 

 by Burmann as plate 192 of the Plantarum Americanum, and upon this plate Lamarck 

 based his Cactus paniculatus , which De Candolle a little later took up as Cereus paniculatus. 

 Ever since, the plant has usually passed under the latter name, with an occasional reversal 

 to the earlier one. 



Until recently, the species has been known only from this old illustration and these 

 brief descriptions. It was collected near Port-au-Prince, Haiti, on the Cul-de-sac, 

 by Dr. W. L. Abbott and Mr. E. C. Leonard, April 1920 (No. 3500); also at the same 

 locality by Mr. H. M. Pilkington, December 1920; also a single branch by Dr. Paul 

 Bartsch at Thomazeau in 19 17 (No. 221). The Abbott and Leonard material consists of 

 wood-sections and herbarium specimens of branches, flowers, fruit, and seeds, supple- 

 mented by living specimens and by fruit and flowers in formalin, together with several 

 habit photographs. 



In habit it resembles Dendro cereus, its branches resemble Acanthocereus, and the 

 small limb of the flower resembles Leptocereus ; but the plant differs from all of these in 

 bearing several flowers at the ends of terminal branches and in developing a kind of 

 cephalium. In the last respect it approaches Neoraimondia, near which we would place it 

 in our present classification.
