| From various sources the editor of this Bulletin has received ample information on the proceedings of botanical research and publication relating to the Malaysian flora. He will be grateful for any notes and references on work in progress. He specially asks co-operation in the completion of the ”Iconotheca” of Malaysian plant collectors and phytographers, of which he invites directors and librarians to take part. It is astonishing that he did not succeed in acquiring any picture of some very Important botanists and collectors, such as Th. Horsfield. William Jack, H. Kunstler, C. Boden Kloss. A.D.E. Elmer, H.O. Forbes, Ch. Gaadichaud, J.D. Haviland, James Motley, L.Th. Leschenault, E.W. Hullett, etc. etc. (cf. page 46). Through the care of Dr. Fr. Verdoorn... |

| For various reasons the space occupied by pre-Linnean Malaysian phytography in this concise history seems too large and out of proportion in comparison to the survey of post-Linnean work. Modern plant description, though based on, and derived from, ancient beginnings and traditions, maintains but slender contacts with plant sciences earlier than the 18th century and it might claim to be allotted by far the larger space on account of its superior results, its greatly increased efficiency, its Consciousness of limitations and capabilities, its output, and its clearness of purpose. There exists, however, during the last decade, an increasing interest in the nearly forgotten botany of centuries long past, not only because of a certain taste for the quaint and... |

| Herbs or undershrubs, usually succulent, perennial, less often annual or biennial. Leaves spirally arranged, opposite or whorled, exstipulate, simple or compound, entire, dentate, crenate, serrate or deeply incised. Flowers ♀, rarely unisexual, actinomorphic, usually cymose or cymose-paniculate, rarely spicate or solitary in leaf-axils, pedicelled or sessile, mostly 4—5-, rarely 3- or polymerous. Sepals free or nearly so, or united into a distinct tube, after anthesis marcescent and persistent as are the petals. Petals the same number as sepals, rarely more, hypogynous, free or variously connate. Stamens either as many as petals and alternate with them or twice their number, perigynous or all or partly inserted on the corolla; filaments free from each... |

| In the past half century much efforts have been made to establish the exact publication dates of several important books, serials, and other issues. An admirable attempt towards assembling these data is the ”Journal of the Society for the Bibliography of Natural History” of which 13 parts have appeared (1936-43). A disadvantage of this journal to the botanist is that it has many pages devoted to zoological publications. Besides, it is exceedingly expensive. Many data are found in the Journal of Botany, the Kew Bulletin and the Journal of the Arnold Arboretum mainly composed by Barnhart, Britten, Fernald, Jackson, Marshall, Merrill, Kuntze, Sherborn, Sprague, Stearn, Wiltshear, Woodward. |

| Delage (1884) and Smith (1906), two authors who published extremely important contributions on Rhizocephala, largely differed in their views concerning the morphology of these parasites. Both regarded the surface of the parasites touching the thorax of the host as the left side, but in other respects they were of a quite different opinion. Delage's (1884) ideas on the morphology of Sacculina were, as he stated himself, different from those of previous authors. In his opinion the dorsal region of the parasite is on the left side of the host, the ventral region on the right side of the host. The left side of the parasite touches the sternum of the crab, the right side the abdomen. As a matter of fact then the region of the stalk must be regarded as the... |

Leaves biseriate, partly radical or subradical, partly cauline, lower congested, higher remote, elongate-linear, rather thick and spongy, bluntmargined; their sheathing bases excreting slime on their inner side. Flowers very numerous, very closely packed in 2 or less often 3, superposed, contiguous or more or less remote terete unisexual spikes; upper spike male; the 1-2 lower ♀; all spikes at the base with a foliaceous bract which falls off long before anthesis; the ♀ spikes here and there between the flowers often with a similar bract. ♂ Flowers consisting of 3 flat hairs together surrounding 2-5 stamens; anthers basifixed, linear, 2-celled;... |

| ( (Report in the ”Gardens’ Bulletin, Singapore”, vol. XI, pt 4, 1947). Prior to the Japanese attack on Malaya, most of the senior staff of the Gardens were seconded for other duties under the Department of Food Control and Information, for at least part of the time. The result was that botanical work was reduced, and considerable arrears of unnamed and undistributed specimens accumulated. The Gardens were maintained as usual, with the addition of demonstration plots of vegetables. |

| The following paper was written in the first place by one of us (H.E.) on the basis of specimens in the Amsterdam and Leiden Museums and on others lent by the Bernice P. Bishop Museum and Dr. W. K. Fisher. The MS was then submitted to the other two authors. One of them (D.D.J.) compared it closely with specimens in the British Museum (Natural History) —fifteen of M. clavigera, the two types of M. victoriae, one specimen each of M. Bradleyi and M. Fisheri—and suggested such alterations and additions as he thought necessary. After a careful study of the types of M. victoriae he concluded that it is safer to regard it as a separate species and added the description given below. In the same way the third author (G. C.) contributed his remarks after the study... |

| Though the list of nomina generica conservanda must be kept as small as possible, both the spirit of the rules and wish of all taxonomists is to aim at stabilizing nomenclature. In general the number of new combinations necessary through the digging up of an old name or the discovery of the identity of a mis-identified plant will be decisive. If the number of new combinations towards the one or the other side are nearly equal, the generic name which has been in current use will generally be favoured. If no new combinations are necessary, the current use only will be regarded as the reasonable decision. |

| Annual or perennial herbs or undershrubs, sometimes fleshy. Leaves simple, entire or subentire, opposite, spread, or spuriously whorled, sometimes minute, stipulate or not.
