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. 
Fic. 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 1917 (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 Dendrocereus, 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 NV eoraimondia, near which we would place it 
in our present classification.
