UMBELLALES. 

 Flov'ers regiilar, usually hermaphrodite. Sfumcn.s usually definite. Ovary 

 inferior, 1-, 2-, or many-celled. Ovules solitaiy, pendulous in each cell from its top. 

 Styles free or connate at the base. Ovules with the coats confluent with the nucleus. 

 Seeds albuminous. Embryo usually minute. 



Order CORNACE^. 



Flowers unisexual or hermaphrodite, regular. Cahj.r-tuhe adnato to the ovary, 

 the limb funning a raised bonier, persistent, truncate, or with as many teeth as 

 petals. Petals 4 or 5, rarely more, (imbricate or) valvate, inserted round an epi- 

 gynous disk or on the calyx-border, rarely wanting. Stamens as many or rarely 2-4 

 times as many as petals, and inserted with them. Filaments filiform or complanate. 

 Anthers with parallel cells, opening longitudinally. Disk epigynous or central, 

 variously shaped. Ovary inferior, 1-4-cellcd, with 1, or rarely 2, anatropous 

 pendulous ovules in each cell. Sti/le simple, with a terminal cntLre or rarely lobed 

 or 2-3-cleft stigma. Fruit an indehiscent drupe, with a 1-4-cellcd stone, or rarely 

 2 bony or crustaceous pyrenes. Seeds pendulous. Albumen fleshy. Emlryo straight, 

 nearly as long as the albumen, the radicle superior, and shorter than the flat usually 

 leafy cotyledons. Trees or shrubs, rarely herbs, with opposite or rarely alternate, 

 simple or slightly-lobed leaves. Stipules none. Flowers usually small in axillary 

 or terminal heads, cymes, or corymbose panicles. 



The Burmese species are all woody plants. 



conyiE^. 



Flowers hermajihrodite. 

 * Petals narrow-linear, valvate. Anthers lasifixcd. Style elongate. Leaves alternate. 



Alangicm, Lamarel;. 

 Sttimcns usually 2 to 4 times the number of the petals. Ovary 1-celled. Alhumen 

 ruminate. Flowers clustered or fascicled. 



A. DEC.\PETAi,rM, Lamk. Burma {fide Mason). 



A. hexapetalum and iomentosum, Lamk. 

 A. Lamarckii, Bedd. 

 A tree, spiny-armed. Petioles 6-8 lines long. Petals 10-6. Pilaments densely 

 pilose at the base. Bracts and bractlets broadly ovate, very deciduous. 



The above synonymy proliably includes two different species. I suspect that 

 Thwaites' A. Lainarclii is a climber. The calyx-tube is apparently sulcate-ribbed 

 (Kurz). 



A. ScNDAxm, Miq. ' Katchall. var. ft Tropical forests of the Andamans. 



A large climber, iinarmed. Petioles shorter. Petals 6. Filaments sparingly 

 pilose at the base. Bracts and bractlets linear-oblong, longer persistent, 

 var. n. Flowers on pedicels J to j inch long, 

 var. ft. Pedicels only 2-3 lines long. 



!Maklea, Po.rhurt/h. 

 Stamens as many as petals. Orari/ 1-3-celled. Albumen homogeneous. Flowers 

 cymose-panicled.

Styrum Javanicum, Bl. 

 Petals about i an inch long or shorter. Anthers with a glabrous connective. 

 Leaves glabrous.
