THK VICTORIAN XATURALIST. 127 



The descriptive notes are elaborated from specimens with 

 young flower-buds and with over-ripe fruit. 



This Australian species is evidently nearest allied to K. 

 racemosa ; but it has only faint nerves of the leaves, shorter 

 petioles, pluriseriate stamens, and perhaps the fruit of K. 

 racemosa, when discovered, may show differences also. 



This new and remarkable plant is named in honour of James 

 McD. Larnach, Esqr., in phytologic appreciation of his sharing 

 as member of the council of our local Geographic Society in 

 the work of promoting the cause of geography in Australia as in 

 New Guinea also, from which exertions botanic science has also 

 benefited. 



Of the Order of Guttiferae. — so little represented in Australia — 

 another plant occurs in Mr. Sayer's collection, from the Russell- 

 River. The leaves are very similar to those of Kayea Larna- 

 chiana, but traversed by rather prominent nerves conspicuously 

 confluent into an intramarginal vein ; the inflorescence is axil- 

 lary, the four sepals are equal, semilanceolar and not enlarging, 

 thus not growing to beyond ^ inch length ; the fruit is ovate- 

 globular, indehiscent, apiculated, about f inch long and one- 

 seeded; the seed turgid-ovate, nearly ^ inch long, exarillate, 

 erect ; the testa membranous and brown ; the cotyledones are 

 oarnulent and partially connate, while the radicle is incon- 

 spicuous. It is intended to establish on this plant, when fuller 

 material is obtained, a distinct genus under the discover's 

 name. Beccari has recently indicated a species of Kayea from 

 Borneo. 



Hydrocotyle Comocarpa. 



Perennial, dwarf, creeping; leaves small, renate — or cordate — 

 roundish in outline, to the middle or less divided into 3 — 5 

 crenated lobes, as well as the petioles almost glabrous ; umbels 

 capitate, few-flowered, on very short peduncles ; styles 

 conspicuous, soon erect or not much spreading ; fruits turgid, 

 roundish, but somewhat dilated upwards, the summit surrounded 

 by a series of flattened bristly hair, elsewhere wrinkled-rough ; 

 the fruitlets seceding, dorsally blunt, one-nerved on each side ; 

 carpophore permanently adnate. 



In Kangaroo-Island ; Otto Tepper. 



Well developed leaves only l — ^ inch broad, so far as shown 

 by the only specimen of the plant obtained, which is a fruiting 

 one. Leafstalks slender, one inch or less long, occasionally 

 somewhat hairy. Fruitlets obliquely cuneate-ovate, not 

 conspicuously compressed except at the commissural line, about 

 yV irich long, dark-brown, sometimes beset laterally with a few
