A plant brought in at that time has been under cultivation at the 

 Gardens, but only produced fertile fronds for the first time during 

 1895. The following is the description by Mr. Jenman : — 



PoLYrODiUM {PTiegopteris) Trinidadense, Jen., n. sp. 



Stipites, 6-9 inches long, void of vesture, slightly channelled, 

 brownish green ; racliis similar ; fronds pinnate, chartaceous, pale 

 green, naked 1-2 feet long, 1 foot or over wide, not reduced at the 

 base, and very slightly at the apex terminating in a simple, linear- 

 ligulate unlobed pinnae, conform to the lateral ones ; pinnoe spreading 

 horizontally, almost sessile linear-ligulate 5-6 lines Avide, 9 inches 

 long, finely serrato-accuminate, the base truncate, not widened, 

 slightly contracted in the lower ones, the margins uniformly through- 

 out sharply dentate (or bi-tridentate) ; veins copious, simple, close 

 grouped, running to the margin, terminating in the serrations ; sori 

 copious, medial on the veins, forming two or three rows, no involucre 

 observable. — Trinidad, Hart, 1895, 



At first sight this might be mistaken for Polypodiun flavo- 

 punctatum, Kaulf., a plant very common in Trinidad, but which on 

 comparison is seen to be very distinct. The pinnge are narrower in 

 this, they are uniformly free at the base, slightly narrowed there, 

 with a terminal one to the frond, simple, only serrated just like the 

 lateral ones, and the translucent spots are quite absent ; whereas, P. 

 flavo-piinctatum has pinnae tAvice or thrice as broad, with copious 

 translucent spots, the upper pinnje roundly lobed along the margins, 

 freely translucently spotted, the upper two-thirds broadly aduate, 

 and decurrent on the rachis, passing gradually into the lobed apex of 

 the frond, there being no distinct terminal pinnae. Plumier's fig. Fil. 

 T. 38 is a very good figure of P. flavo punctatum, and shows clearly 

 how distinct these two species are.

In the front portion of the Koyal Botanic Gardens facing south, 

 stands a large tree which has long been a favourite with visitors, on 

 account of the dense shade it aff"ords at all seasons of the year. It 

 stands some sixty feet in height Avith a spread of branch about the 

 same in diameter as the height. This tree produces a pod or bean
