1. The root tip of Cucurbita maxima possesses a single histogen from which all the primary root tissues arise. 2. The primary root is exarch, tetrarch. Differentiation of the large central metaxylem vessels is retarded; pith is not present. 3. The primordium of a secondary root is formed from the cortex, including the endodermis, as well as the pericycle of the primary root. 4. The transition extends from approximately 1 cm. below the peg to just above it. At the lowest level pith differentiates in the center and the metaxylem takes a peripheral position just within the phloem. Each primary xylem strand diverges into two arms extending laterally and joining the metaxylem. These arms separate, resulting in a siphonostele of four tangential transition bundles. These divide into two parts each, forming a total of eight bundles which become endarch. 5. Of these eight bundles usually two pairs anastomose, then divide into three, producing a total of ten bundles which continue through the hypocotyl. Additional bundles may arise. 6. The bundle is considered bicollateral on the basis of ontogeny; it shows a differentiation of internal phloem from the procambial tissue at the same time that the external metaphloem differentiates. (The study of a single species allows no interpretation on the basis of phylogeny.) 7. A suggestion is made concerning the differentiation of two types of phloem, the one called fascicular phloem and the other called connective phloem. Differences in origin, structure, and distribution of the two types are described. 8. In the cotyledonary node tangential anastomoses produce a cotyledonary plate of four parts. Continuations from these form two traces to each cotyledon. Before the cotyledon diverges completely, each trace branches laterally to form a basal vein from which arise four or more bundles which are the principal veins in the blade of the cotyledon. 9. The bundles of the epicotyl differentiate against the parts of the cotyledonary plate. The epicotyl is retarded in its development except for the median trace to the first foliage leaf. The early differentiation of this trace may account for the characteristic short first internode.
If the Bosnian crisis of 1908-9 may properly be described as the dress rehearsal for 1914, the Austrian project, announced early in 1908, to construct a railway from the Bosnian border through the Sandjalc of Novibazar helped to set the stage. Part of the original program to link up the Ottoman realm with central Europc by iron highways, this line had been overlooked for decades as finance, engineering, and diplomacy spent themselves on the great trunk line, the Orientbahn, running like a backbone down the Balkans to Constantinople, with a branch connecting Nish with Salonica via Uskub. From Uskub a spur penetrated northward to Mitrovitza; another linked Salonica with Monastir. Though small in itself, the reappearance of the Novibazar scheme heralded the revival of the perennial Austro-Russian rivalry over the Near East in an acute form, sharpened international animosities generally, strengthened latent dreads of Teutonic hegemony over the Balkans, and gave an impetus to a plethora of competing railway projects. In spite of Austria's renunciation of her rights in the Sandjak as part of the settlement attendant upon the annexation of Bosnia-Herzegovina, the railway plan was not abandoned, and until well along in 1909 hopes were cherished that the Sandjak road - even today unconstructed - would be built.
The present publication is intended to be a monograph on the family of Burmanniaceae. It is divided into three parts: General Part, Critical Part and Taxonomical Part. The first part, General Part, contains general remarks on the taxonomy, distribution and use of the family. The second part, Critical Part, contains general and geobotanical remarks on the genera of the family, whereas the third part, the Taxonomical Part, gives the determination keys to the tribes, subtribes, genera, sections, subsections and species, the description of these groups with literature, distribution and the indications of the types. New varieties, species and larger groups are described in the taxonomical part in foot-notes.
