A singular plant, belonging to a section of the genus 
Spiranthes in which the perianth 1s decurrent on the ovary ; 
a tendency to which structure may be seen in S. aphylla 
(Plate 2797), avd S. speciosa (Plate 1374), and S. orchioides 
(Plate 1036); whilst in 8. grandiflora (Plate 2730) it is 
carried to as great an extent as in 8. euphlebia. 
This plant was received from Messrs. Shuttleworth, 
Carden, and Co., who imported it from Brazil with S. 
speciosa, and it flowered in the Royal Gardens in November 
of last year. 
Descr. Stout, erect, twelve to eighteen inches high. 
Leaves all radical, five to six inches long, by one and a half 
to two inches broad, linear- or obovate-oblong, contracted

undulate, pale green with distant white blotches. Scape 
light greenish-brown, glabrous below, above pubescent ; 
sheaths numerous, erect, dark brown, lower amplexicaul 
with lanceolate acuminate tips; upper narrower, Semi-
