plants are quite upright, without the pendulous or prostrate barren 

 branches so characteristic of our common plant ; the leaves too are 

 relatively larger and much fatter, approaching in that respect those of 

 dasyphyllum.

1099 (2). Apium Moorei. Root perennial of long white fibres. 

 Stem often roots freely from its lower joints, sometimes from nearly all. 

 Plant light green, glabrous, 6 — 30 in. Stem weak, much branched 

 from near base. Leaves pinnate and very varied. Upper leaves of 7 — 9 

 leaflets, leaflets broadly ovate, or obovate to narrowly lanceolate or 

 oblanceolate, or narrowly elliptic, variously cut, sometimes with a few 

 broad blunt teeth or even lobes ; narrower leaflets cut into narrower, 

 acuter teeth or even lobes, sometimes consisting of three subequal 

 lobes. Lowest leaves if fine cut, usually larger in general area than 

 upper leaves ; pinnate — 1 1 leaflets, leaflets usually cut into long acute 

 linear segments. Middle leaves show gradual progress from upper to 

 lowest. Petiole long. Sometimes leaves similar all through the 

 plant. Lowest leaves very rarely cut into capillary segments. 

 Flowering umbels few in comparison to the foliage, opposite leaves, 

 long-stalked, peduncle nearly always > rays. Involucral bracts rare, 

 minute. Umbel rays 2 — 3, rarely 1 or 4. Umbellules many flowered 

 ( — 12). Petals broadly ovate, very small white. Bracts of umbellule 

 many ( — 6), very unequal. Styles of flowers and undeveloped fruit 

 rather variable, always intermediate in length between nodiflorum and 

 inundatum, varying about as much as style of inundatum does. 

 Pipe fruit not seen on any plant of 150 — 200 seen, and only one fruit 

 on one plant that even promised to develop. That looked like 

 inundatum. Plant not a late flowerer ; one Irish specimen, June ; 

 many in full flower, July ; many in August. After fall of petals the 

 fruit gradually wrinkles, withers, drops, and shows no signs of ripen- 

 ing. Plant propagates itself vegetatively. Probably a hybrid between 

 nodiflorum and inundatum, because (1) very variable habit andfacies,
