The Catalogus Plantarum Horti Ulenpassiani is a catalogue of plants cultivated in the gardens and greenhouses of Ulenpas, the estate of H.A.W. Baron van Rouwenoort and situated near Hummelo in the Netherlands’ province of Gelderland. It contains lists of plant-names and the only species of which a description and a plate are given is the above mentioned Anthericum Rouwenortii.

Description: When revising the Visca of the Malay Archipelago and Indo-China, I met with some nomenclatorial difficulties, for which a more thorough study of the British-Indian Visca seemed necessary. The distinction of the species in HOOKER’S Flora soon appeared not to be depended upon. At the time of HOOKER’S revising the British-Indian Loranthaceae, only a scanty quantity of herbarium was available, and, the distinction between several species being extremely difficult, it is no wonder that HOOKER’S treatment of Viscum is no more up to date now. As appears from notes on herbarium sheets, GAMBLE later made a rather thorough study of the British-Indian Visca, which was only partly included in his Madras Flora, but he did not include the species of adjacent countries in his study. We now have a much larger quantity of herbarium materials at our disposal; several species described from outside British-India appeared to occur inside its frontiers, and new species had to be described from British India and China. Therefore a critical revision of all the Asiatic species seemed not to be superfluous. Moreover, the close relationship of the Australian Visca with Asiatic species made it desirable to include also the former in this revision. A revision of all the Asiatic, Malaysian, and Australian Visca would therefore have been the result, if not political circumstances had rendered it impossible to obtain the materials of several important Herbaria in the Tropics. I therefore preferred to close my study on the genus Viscum provisorily, and to publish it in the present form, in expectation of better times. The Herbaria upon which the present revision is based, mainly are those of Kew Gardens (K), and the Dehra Dun Forest Experiment Station (DD), the Viscum materials of which were kindly sent to me for examination. Many data, however, could be added from other Herbaria, such as those of Buitenzorg (B), Berlin-Dahlem (BD), the British Museum of Natural History (BM), Berkeley (UC), Brisbane (Bris), Edinburg (E), Geneva (G), Göteborg (Göt), Groningen (Gro), Honolulu (H), Leiden (L), Manila (M), Paris (P), Shillong (Sh), Singapore (S), and Vienna (V).

Trees with hard and often reddish wood and sympodial branchlets; stipules caducous or none; leaves more or less coriaceous, often obovate with rounded apex, lower side often lighter coloured than upper one, with selereids (f. LECOMTE); tertiary nerves very slender and numerous, in general parallel to the secondary ones which are hardly more conspicuous, often with a minute reticulation between; inflorescences axillary, fasciculate; sepals in two rows of 3 each; petals 6, with narrowed base inserted on a corolla-tube as long as or shorter than the petals, each of them with two dorsal appendages which are mostly about as long as the petals and of the same shape but often narrower and more acute, rarely much shorter (about ½ or less in M. kanosiensis and M. vitiensis); stamens 6, epipetalous; staminodes 6 alternipetalous and in the same row as the stamens, differently shaped, broadly ovate, acuminate to small or subulate, irregularly dentate or fimbriate, trifid or bifid, sometimes scalelike, very rarely reduced to none (M. fasciculata, vitiensis) ovary 15—6-celled, pubescent, but sometimes surrounded by a glabrous adnate disc; cells 1-ovuled, ovules ventrally or basiventrally attached; fruit drupaceous, but pericarp often rather dry, 6—1-seeded; scar of the seed ventral or basiventral, long and narrow or rarely larger and ovate (fasciculata) or circular (M. Bojeri, dissecta, Eickii) albumen abundant, the cotyledons thin. About 74 species in all tropical countries, of which about 25 in Central America, about 34 in the African region and some 15 in Asia-Polynesia.

Caules (2 suppetunt) graciles, ad 55 cm longi et ultra (supra basin decerpti), internodiis teretibus, inferioribus 2.5—6 cm longis, ad 4 mm diametro, superioribus plerumque paulo brevioribus, gradatim tenuioribus, ad 1.5 mm diametro, nodis vetustioribus incrassatis nonnihil applanatis, ad sesquiplo crassioribus quam internodia, iunioribus applanatis et dilatatis. Folia opposita vel subopposita; petiolus 3—8 mm longus, basi subteres, 1.5—1.75 mm latus, versus laminam paulum dilalatus et applanatus, subtus rotundatus, supra fere planus; lamina ovato-lanceolata, 5—12 cm longa, 1.5—4 cm lata, sub basi cuneata in petiolum contracta, apicem obtusum vel subobtusum versus leviter acuminata, margine saepe irregularis, nonnihil flavida (in herbario), utrinque opaca vel facie superiore nonnihil lucida, inferiore punctulis minimis atris numerosis, nervatura pinnata, costa facie superiore distincta usque ad apicem, plana sed saepe nonnihil prominula, facie inferiore a basi ad apicem gradatim minus prominens, saepe subcarinata, nervis lateralibus et venis utrinque visibilibus, facie inferiore distinctioribus quam superiore. Inflorescentiae racemosae pedunculatae, singulae vel binae vel ternae in axillis foliorum adultorum (nunquam in axillis foliorum rudimentariorum quae passim inveniuntur inter folia normalia); axes in scrobiculis corticis inserti, involucris nullis, basi nonnihil incrassati, caeterum subteretes, a basi circiter 1 mm crassa ad apicem c. 0.3 mm crassum sensim attenuati, 10—25 mm longi, pedunculo 3—10 mm longo, saepe nonnullis insertionibus et bractea singula sterilibus, parte florifera paribus florum 2 ad 5, nodis paulum dilatatis; pedicelli teretes, plerumque 2—3 mm longi, 0.25 mm crassi, basi in annulum incrassati; bracteae, ut bracteolae paulo minores, ellipticae, 0.75—1 mm longae, obtusae vel acutae, basi paulum connatae vel liberae, leviter concavae. Calyx urceolatus, supra partem inferiorem ellipsoidem circiter 1.5 mm longam 1 mm latam distincte contractus, deinde in partem superiorem infundibuliformem circiter 0.5 mm longam integerrimam ampliatus, parte libera autem brevissima. Corolla statu alabastri adulti ad 33 mm longa, supra basin rotundatam partibus 2/3 inferioribus late tubulosa vel magis inflata, ad 4 mm lata, ad apicem partis ampliatae alis 6, deinde contracta in collum 6-angulum lateribus cavis, 1.5 mm diametro, apice incrassata in clavam obovatam 6-angulam lateribus cavis costisque obtusis; denique divisa in lacinias 6 recurvas usque ad medias alas. Filamenta circiter 7 mm longa, antherae c. 2 mm longae, obtusae. Stylus corollae subaequilongus, circiter 1 mm supra basin articulatus, parte basali persistente versus basin cum disco 6-tuberculato connata supra 6-angula, deinde teres usque ad partem in collum inclusam ibique ad dimidiam crassitudinem attenuatus, in 2 mm superioribus iterum incrassatus, apice stigmate subgloboso, c. 0.8 mm diametro. Fructus ignotus. This Macrosolen is perhaps conspecific with M. tenuiflorus DANSER, which is likewise from East Borneo (Kong Kemoel), but the specimen described here differs by longer corollas and stamens, non-oviformous style-base, and narrow leaves. According to the description it is ap parently also very near M. javanus, but it is distinct by different shape, colour, and consistency of the leaves, the lack of black parts on the corolla, smaller bracts, and urceolate calyx.

Description: In working up the materials of the genera Anaphalis, Gnaphalium and Blumea for Backer’s “Flora van Java” some new species, varieties and forms have come to light. The results of this work can by far not be considered to be complete, as the great lot of specimens collected in Java belonging to the genera under consideration are preserved in the “Herbarium van’s Lands Plantentuin te Buitenzorg”. Owing to the war these specimens were not available as yet. However, it may be useful to publish the novelties hitherto discovered.

Description: Korthalsella Dacrydii (RIDLEY) DANSER, the only species of its genus that is parasitic on Conifers, was, up to the present, only known from two mountains, viz., Mt. Tahan in the Malay Peninsula, and Mt. Gede in Java. For the latter mountain it was, for the first time, not discovered in the living state, but, by Dr VAN STEENIS, on herbarium specimens of Podocarpus imbricata, collected by KOORDERS and VAN DER HOEVEN in 1890. Later it was collected several times on Mt. Gede in the living state. While examining the materials of Podocarpus and Dacrydium of the Leiden, Buitenzorg, and Groningen Herbaria, I was so fortunate as to discover, in the same way as Dr VAN STEENIS did, several new localities of Korthalsella Dacrydii, and these not only in Java, but also in Sumatra, Borneo, and Timor. The localities now known are the following.
