ADDITIONS TO THE HONGKONG FLORA.
Illicium Griffithii, Hook. et Thoms. ? Five or six bushes 10 to 12 feet high, of what is apparently this species, were found growing at the top of a very steep ravine on Mount Nicholson. The plants were thriving in the crevices of rocks and on the steep hillside. When found in December, 1906, they were in fruit and bud. An interesting addition to the Flora. Previously known only from India and from the province of Yunnan in China.
Xylosma racemosum, Miq. Several small bushes were discovered on Mount Victoria on the hills to the East of the Mountain Lodge Grounds, flowering in July. Found in Japan and previously recorded from Amoy and Canton.
Sagina Linnai, Presl.? A small weed not uncommon in China and widely spread in North temperate parts of the world.
Eurya sp.-Detected on a sheet in the Herbarium with Eurya Macartneyi, Champ., from which it differs by having united styles. The label attached to the sheet reads:- -Mt. Gough, 2nd April, 1880.
Callitriche sp.-A weed found growing with Sagina Linnæi in damp shady places.
Hydrocotyle Wilfordi.-Maxim. Not uncommon in damp ground in the neighbour- hood of Sokunpo. Recorded from Korea, Japan and Formosa.
Psychotria sp.-A shrub growing in the Happy Valley woods and flowering in June. The species has the habit of Psychotria elliptica, Ker, but the shape of the corolla is quite different and the leaves are distinct. Only two species of this large genus are recorded from China, both of them natives of Hongkong.
Lysimachia candida, Lindl. This makes the third species of the genus found in the Island. The present plant was discovered in swampy ground at Sokunpo. It is a common plant in central and North China.
Jasminum undulatum, Ker, var. elegans, Hemsl.? This is a plant which has apparently escaped from gardens, although it is now found halfway up Mt. Victoria amongst indigenous vegetation.
Phlomis rugosa, Benth. Discovered on Mt. Parker. Previously found in the provinces of Szechuen and Kwangtung and in India, Malaya and the Philippine Islands.
Litsea sp-A small tree in the Happy Valley woods, about 15 feet high, and not matched in our Herbarium.
Pilea peploides, Hook. et Arn. A weed found in damp, shady places and recorded from various islands in the China Sea.
Quercus sp. -A single tree, of what is apparently an additional species to the flora, was found growing in the Happy Valley woods.
Castanopsis sp. A tree about 15 feet high on the North side of Mt. Kellet. The fruits are very much like those of Castanopsis armata, Spach, ovoid in shape 21" long and 11′′ across at the base. The leaves however are more like those of Castanopsis Lamontii, Hance.
Calamus sp. A fifth species of this genus was discovered in the Happy Valley woods in April. Only three plants were seen. The leaves are 4 or 5 feet long with tail-like appendages. The habit is that of Calamus Margaritæ, Hance, which is however quite distinct.
Adiantum sp.-Found on Mt. Gough by Fleet Surgeon C. G. MATTHEW, R.N., in November.
Nephrodium prolixum, Baker. Several plants were detected growing on the bank of the stream to the East of Mountain Lodge. A native of India, Ceylon and Mauritius.
