51008. Cestrum sp. Solanacese. 



"A very handsome Cestrum with yellow flowers, from Baguio, at an 

 altitude of about 5,000 feet, which should be a valuable acquisition to the 

 ornamental flora of Florida." (Wester.) 



51009. Pandanus tfctorixj.s Parkins. Pandanaceae. 



A shrubby plant, up to 20 feet high, rarely erect ; the stem is supported 

 by aerial roots. The glaucous green leaves are coriaceous, sword shaped, 

 and 3 to 5 feet long, with the marginal spines pointing forward, those on 

 the midrib, forward or backward. The spadix of numerous cylindrical 

 spikes of male flowers is 2 to 4 inches long and 1 to li inches wide, and 

 is inclosed in a long, white, fragrant spathe. A prerfume which is much 

 esteemed in Java is obtained from the male flowers. The solitary spadix 

 of female flowers is followed by a yellow or red fruit which is an oblong 

 or globose syncarpium, 6 to 10 inches long and broad. The plant ia 

 native of Konkan. Bombay, in sandy places near the seacoast. It is 

 often planted and is known as the screw pine. (Adapted from Cooke,

 (Citrus australasica F. Muell.) Finger lime. 



From Wellington Point, Queensland. Australia. Seed presented by James 

 Pink. Received July 29, 1920. 

 One of the most curious and interesting of the citrus fruits, native to the 

 mountainous scrubs of the coastal region of northern New South Wales and 

 Queensland. The young plants have more or less horizontally arranged branch- 

 lets, with very short internodes, small oval leaves, and stiff erect spines. The 

 long, slender, cylindric-fusiform fruits, 6.5 to 10 centimeters long and 1.5 to 

 2.5 centimeters broad, are often slightly curved <nd frequently show a short 

 blunt protuberance at both base and tip. The juice is sour and rather strongly 

 pungent. The young plants of the finger lime showing the juvenile foliage 

 arranged in tiers somewhat like a young araucaria plant, are very orna- 

 mental and should become better known for decorative purposes. It is a 

 promising Jjedge plant, because it is very spiny and can be grown from cut- 

 tings. It is decidedly more hardy than the lime or lemon and may prove 

 useful in breeding new types of hardy citrus fruits. (Adapted from Joiinial 

 of the Wa-shinr/ton Academy of Sciences, vol. .5, p. 572.)
