120 The Biology of the Lowland Plants. 
The growth-forms and the number of species belonging to each are as 
follows: — ı. Annuals and biennials ı7 including, — tufted-fern ı; tufted- 
grass 2; mat-form 2 (non-rooting 1, rooting ı); rosette-form ı, erect-branching 10 
and semi-erect branching ı. 
2. Perennials 270 divided into: — a) Wandering (117), — «) semi-woody, 
— mat-form ı, — ß) herbaceous, mat-form 57 including herb-mat 43, grass- 
mat 2, rush-mat 2, fern-mat ı0 (filmy 8); erect-creeping form’) 43 (fern 29, 
herb 6, grass 5, rush 3); orchid-form ıo (summergreen); straggling-form 1; 
herb-turf 1; Utricularia-form 2 and Iris-form 2. b) Spot-bound (153), — 
«) semi-woody, — erect-branching ı0; tuft-fern 3; rosette-form 3. — P) herb- 
aceous, — tufted-form 5o including tufted-fern 24 (flmy 2), tufted-rush 13, 
tufted-grass 13; tussock 25 (grass 19, rush 6); erect-branching 15; rosette-form 10 
(herb 9, grass ı); mat-form > orchid 27 (summergreen); straggling-form 2; 
Irıis-form 4; holosaprophyte 
The saprophyte Bea, Hill) according to CHEESEMAN (1909 : 141, 142) 
is found in decaying leaves and humus at the base of Podocarpus dacrydioides. 
There is a branching, fleshy rhizome 5—ıocm long and ı—ı.5 mm thick. 
Leaves are wanting and the vegetative parts are colourless. One-flowered 
peduncles, 5 mm to ı5 mm in length, are given off from the axils of the 
minute in bracts. The flower is rose-pink and about 1.5 cm long by 
mm ; 
The ar of the herbs &c. may be characterized as follows: — com-
