Garden and Forest.

Catopsis; and these are all. The genera with more showy 

 flowers than these, such especially as Billbergia and Pit- 

 cainiia, are more strictly tropical in their character. Pil- 

 cairnia is, next to TUla7idsia. the largest genus of the order, 

 and its seventy-five species are found mainly in the region 

 lying east of the Andes from Brazil to Me.xico, while none 

 occur outside of the tropics. On account of their highly 

 ornamental flowers a very large proportion of them have 

 been in cultivation in the gardens of Europe, but they are 

 rarities in our own hot-houses. 



We have figured for this week (page 197) one of two 

 species of Pitcairnia which were discovered by Dr. Edward 

 Palmer in 1886, near Guadalajara in Me.xico, the most north- 

 ern locality on the continent for any member of the 

 genus. The striking colors of the flowers and bracts 

 cannot be shown, but most of the other characters are 

 well represented. The short outer bract-like leaves that 

 cover the swollen base of the stem are prolonged, as in 

 many other species, into slender appendages which are 

 very sharply barbed. The plant is otherwise unarmed. 

 The few proper leaves are long and linear, and are cov- 

 ered on the under side with a white, scurfy pubescence. 

 The floral bracts are mostly of a deep rose color, and the 

 flowers themselves are bright scarlet. Heat and drought 

 are the delight of these plants, or at least they are capable 

 of enduring and thriving under an extreme of both. The 

 present species was found growing in the crevices of rocks 

 in deep, hot ravines, and would probably need, like the 

 rest of the genus, the heat of a stove for its successful 

 cultivation. 6". W. 



Cypripedium hellaiulum is the name given by Professor 

 Reichenbach to a new species which is closely allied to C. 

 GodefroycE, and which might fitly be described as a giant 

 form of that fine species. The flowers are described by 

 Messrs. Hugh Low & Co. as nearly four inches across, and 

 many of the leaves are ten inches long, and more than 

 one-fourth as wide, and marked as finely as those of Pha- 

 lixnopsis Schillen'ana, while their under surface is purplish 

 red throughout, or marbled with deep red. The flowers 

 are of perfect shape and profusely spotted. 



Plant Notes. 

 Primus pendula. 



THE tree which is figured on page 198 of this issue is 

 one of the loveliest in flower, and the most pleas- 

 ing and graceful in habit of all the plants \\ hich have 

 been transferred from the gardens of Japan to those of 

 this country. It is the Pninus peiidida * of Waximowicz ; 

 a species first described by Von Siebold in his " Synopsis 

 Plautarum Qilcoiiiinicaium universi regni Japonici" a work 

 which, unfortunntely, I have been unable to find in this 

 country. M. Franchet has kindly examined, however, the 

 copy of this rare book in the Paris Museum, and informs 

 me that Von Siebold in his description of the plant retained 

 the Japanese name liosakura, that is pendulous, for this 

 species, so that Maximowicz, instead of adopting Von Sie- 

 bold's specific name, translated it into Latin, changing his 

 Cerasus liosakura into Primus pendula. Were the laws of 

 botanical nomenclature rigidly adhered to, it should be 

 known as Primus liosakura, a change which, under all the 

 circumstances of the case, it is certainly not desirable to 

 make, at least for garden purposes. 



Pruniis pendula, as now seen in gardens, has probably 

 been somewhat changed by long cultivation from the wild 

 type; indeed, specimens of what is evidently the same plant 

 collected in the forests in the central part of Nipon vary 

 very considerably from it in the length and breadth of 

 the calyx-tube and in the much smaller corolla. Here 

 it is a small tree twelve to fifteen feet high, with wide- 

 spreading, flexible, pendulous branches, those on the lower

part of the stem horizontal, with pendulous ends, the upper 

 widely arching from the trunk. The bark resembles that 

 of the common Cherry tree, although light brown in color. 

 The flowers, which precede the leaves, are produced from 

 scaly, lateral buds in two to four flowered fascicles. They 

 are borne on Long, slender, pubescent pedicels, which are 

 destitute of bracts. The tubular calyx and incised calyx- 

 lobes are densely pubescent and dark red in color. The 

 petals are half an inch long, ovate or obcordate, pale rose 

 colored, and more than twice as long as the stamens. The 

 ovary is slightly, and the style is densely, covered with 

 long, nearly white, hairs. The leaves are three or three 

 and a half inches long, slightly hairy, when young, on the 

 under side, twelve to fifteen ribbed, ovate and longly acu- 

 minate, sharply glandular-serrate, with two conspicuous 

 glands near the base of the blade. The stipules are linear, 

 glandular, and, like the short petioles and young shoots, 

 pubescent. The fruit is black, the size and shape of a pea. 



A second species of Primus (Fig. ii), very similar 

 in general appearance to Prunus pendula, is confounded 

 with it in gardens here. It has the same general habit and 

 the same long, pendulous branches, but the bark is darker, 

 and hardly to be distinguished from that of the common 

 Cherry tree. The flovi'ers are corymbose on short leafy 

 branches, and the pedicels are conspicuously bracted at 

 the base, and, as well as the shorter and paler calyx tube, 

 are covered with a few scattered hairs. The petals are 

 more narrowly ovate than those of the last species, entire 

 and rarely truncate, much paler pink or nearly white in 

 color. The ovary is quite smooth, but the style is densely 

 coated with hairs. The leaves which appear shortly after 

 the opening of the flowers are broader, thinner and more 

 deeply and irregularly cut on their margins and are only 

 6-8 ribbed. They are pubescent on the under side, as well 

 as the petioles and young shoots, and have two conspicu- 

 ous orange-colored glands at the base of the blade. Their 

 larger stipules are three-lobed and glandular. The corym- 

 bose inflorescence of this plant, the forked stipules and 

 the texture and color of the young leaves point to some 

 form of Prunus Pseudo-Cerasus, but the style is con- 

 spicuously hairy, and I therefore very doubtfully refer it 

 to Maximowicz's Prunus JSIiqueliana,'^ authentic specimens 

 of which, however, I have not been able to examine. 



The two species are cultivated in nurseries under the 

 name of Cerasus Sieholdii pendula flore rosea, and flore cameo. 



Under the name of Cerasus Herinquiana M. Lavallee 

 described and figured in his Icones, I. xxv., a plant which 

 seems identical with the second of these two Cherries. 



These plants were sent to the Arnold Arboretum sev- 

 eral years ago from one of the Dutch nurseries. Both 

 species flower here every year and are exceedingly hardy, 

 requiring no special care or cultivation. They can be in- 

 creased by grafting upon the common Cherry. The grafts 

 should be inserted close to the ground in order to secure 

 the peculiar habit and full beauty of these trees. When 

 grafted as standards, as is often the case in nurseries, they 

 are then less graceful and lose much of their peculiar 

 habit of growth.

 of .\rthur Blake, Esq., in Brookline, Massachusetts.

The finest varieties of the common Lilac {Syrhiga vul- 

 garis) in the large collections in the neighborhood of Bos- 

 ton are Philamon and Marie Lagrange. The former has 

 large, broad, compact panicles of dark purple-red flowers, 

 nearly half an inch across the limb when expanded. This 

 has the deepest and richest colored flowers of all the Lilacs. 

 Marie Lagrange has very large pure white flowers in im- 

 mense panicles. Both varieties are of European origin ; 

 and they grow rapidly and vigorously, and soon make 

 fine specimens. C. S. S.
