Order CLXXXVII. LYGODYSODEACE^. 
LYGODYSODEACEiE, Bartl. Ord. Nat. 207. (1830) ; Martius Conspectus, No. 161. (1835). 
— Rubiace^ § Paederieae, DC. Prodr. 4. 470. (1830). 
Differential Character. — In all things Cinchonaceous except; Ovary composed of 
two confluent carpels, 1 -celled, with 2- ovules ; style single. Pericarp brittle, burst in four 
directions from the base, not adhering to the seeds, 1 -celled. Placenta} 2, free, rising up 
between the pericarp and the back of the seeds. Seeds 2, pendulous from the apex of the 
placentae. Albumen 0. Em5ri/o straight, foliaceous, compressed ; radicZe short, inferior. — 
Twining shrubs. Stipules single between the petioles. 
Affinities. According to Bartling, from whom the foregoing differential 
character has been taken, an order intermediate between Apocynacese and 
Cinchonaceae ; diflfering from the latter in the remarkable structure of the fruit 
and seed. If the latter is rightly described, the order must indeed be recog- 
nized ; but De Candolle, who seems to have examined the same materials as 
Bartling, gives quite another account of the structure, and reduces the supposed 
order to the § Paederieae of Cinchonaceae. According to De Candolle, what 
Bartling caUs pericarp is calyx, and his seeds are carpels, and consequently all 
the most remarkable features of the order disappear, with the exception of the 
absence of albumen. If Bartling is right, the radicle must be at the end of 
the seed most remote from the hdum ; if De Candolle’s views are correct, the 
radicle will probably be in its usual place. This question deserves attention 
from those who have access to the necessary materials.

Order CLXXXVIII. CAPRIFOLIACE.^. 
The Honeysuckle Tribe. 
Caprifolia, /mw. Gen. 210. (1789) in part. — CaprifoliacejE, Rich. Diet. Class, Z.\1 2. 
( ) ; Lindl. Synops. 131. (1829) ; DC. Prodr. 4. 321. (1830) ; Bartl. Ord. Nat. 
213. (1830). 
Essential Character. — Calyx superior, 4-5-cleft, usually with 2 or more bracts at 
its base. Corolla superior, monopetalous or polypetalous, rotate or tubular, regular or irre- 
gular. Stamens epipetalous, equal in number to the lobes of the corolla, and alternate with 
them. Ovary with from 1 to 3 or 4 cells, 1 of which is often monospermous, the others 
polyspermous ; in the former the ovule is pendulous; style 1; stigmas 1, or 3-4. Fruit 
indehiscent, 1- or more celled, either dry, fleshy, or succulent, crowned by the persistent 
lobes of the calyx. Seeds either solitary and pendulous, or numerous and attached to the 
axis ; testa often bony ; embryo straight, in fleshy albumen ; radicle next the hilum. — 
Shrubs or herbaceous plants, with opposite leaves, destitute of stipules. Flowers usually 
corymbose, and often sweet-scented. 
Affinities. As left by Jussieu this order was a heterogeneous assemblage ; 
as altered and better limited by De Candolle and others it seems to be in all
