C. SPiNOSA, Jacq. Viscid-pubescent, strong-scented, 3 or 4 feet high : a pair of stipular 

 short spines under the petiole of most leaves (in the tropics not rarely some little prickles 

 on the petiole also) : leaflets 5 to 7, oblong-lanceolate ; bracts mostly simple : flowers rose- 

 purple varying to white : petals commonly an inch and stamens 2 or 3 inches, and stipe of 

 the linear capsule about 2 inches in length: style hardly any. — (Mill. ?) Jacq. Enum.

 simple, oblong-lanceolate to linear : raceme dense : petals 3-to()thed, rose-color (rarely white) : 

 appendage to torus conspicuous, flat : sti])e about the length of the pedicel, shorter than the 

 pendulous capsule ; this sometimes linear, terete and toruluse, over 2 inches loTig, sometimes 

 variously shorter, elongated-oblong, compressed : seeds mostly numerous, smooth. — Fl. i.
