i In the curves of the hybrids which show in the 

 first place a very close correspondence with each other, 

 and in the second place a closer correspondence, on the 

 whole, with the curves of Amaryllis belladonna than with 

 those of Brunsvigia josephina, the hybrid curves are 

 for the most part either lower than or practically the 

 same as the Amaryllis carves, in only four instances 

 are the curves higher, and then in an unimportant degree. 



- OK AMARYLLIS, BRCNSVIOIA, AND BRUXSDONNJB. 



The botanist has assigned Amaryllis belladonna and 

 Brunsrigia josephina to separate genera. Upon the 

 basis of the peculiarities of their starches in their histo- 

 logic properties and reactions with the various agents and 

 reagents, it seems that these species may be regarded as 

 being members of either closely related genera or well- 

 separated species of the same genus, such as repreaen- 

 of snbgenera; but the data are too limited to 

 . more than speculation. The most remarkable 

 feature* of these records are: (1) in the hybrids the 

 many extraordinary low or high reactivities, especially 

 the former, that exceed the parental extremes, this being 

 noted in 15 out of the 28 reactions; (2) the absence 

 of sameness of any reaction as that of the pollen parent ; 

 the sameness of the reaction as that of the seed 

 parent in 4 reactions of one and 6 reactions of the other 

 hybrid. The marked departures of the hybrid curves 

 -'...-.MI in excessive or deficient reactivities in comparison 

 with the reactivities of the parent* seem to be more sug- 

 ueric parents than of parents belonging to 

 th> same genus.

'I In- additional matter treats of descriptions of Bruiu- 

 tul \ niaryllis parlceri. and A. parkeri alba 



(A. brllatlunna kevensu alba), and comparisons of the 

 starches of H. (ubergtni, A. parkeri alba, Bnuudonna 

 sandera alba, and H. tandtra. 



Bnuudonna tvbergeni, A. parkeri. and A. parkeri 

 alba are of especial interest in conjunction with the 

 foregoing studies of the Amaryltis-Hrunsrigia-Hruns- 

 donna group because: the first is known to be a hybrid 

 of Hrunsvigia and Amaryllis; the second is looked upon 

 as being probably a Brunsvigia- Amaryllis hybrid; the 

 third is a variety of the second and is regarded as being 

 the same as A. belladonna kevensis alba, the parentage 

 of which is unknown; and the last two are known hy- 

 brids of Amaryllis-lirunsrigia, but without positive 

 knowledge of the direction of the cross. Appertaining 

 to the foregoing, the following data appeared in The 

 Gardeners' Chronicle, 1909, XLT, 57; 1911, L, 210: 



Bniiudonn tubrrye*i: Mr. C. O. Tubergee, Jr.. thu* de 

 scribes the circumstances of a croae between tfninrifto 

 /utffkintr and Amarylli* brlladonnu: 



Principally with a view of ascertaining toe parentage of the 

 Kew variety of Amarylhi fc-U4o*M (see illiutratlon In Tnr 

 <iardrn, November IV, 189H; alw> note* In Thr Otrdnurs* 

 . M..ni.-le. Krl.ruary 0, 1901, etc.), in the autumn of IBM I 

 artificially impregnated Hrvninyio jutrpfiintt with the pollen 

 of Amaryltit Mlfdonmm. Seedt formed freely, aa the two gea- 

 era, Brwunyi* and Anutiyllit. are vtry nearly related. Aa 

 could be foreseen, with ilow-growing Rnmrrift* jotrpkina aa 

 the female parent, a long time had to elapa* before the leedling 

 planta would be strong enough to reach flowering ilxc. After 

 18 year* of patient waiting, two of the itrongwt bulb* pro- 

 duced flower pikea in September of Uat year. When the 

 hybrid planta had been growing for a few aeaaoaa It became 

 evident that they differed in habit from the Kew variety of 

 Amcryllii teHi/omn, which produce* a leaf utem of about 4 

 incbee high, wbereaa my hybrid* all bear the character of 

 BnHuvigim fottpktna in the foliage, leavea being formed di- 

 rectly above the neck of the bulb*. The infncion of belladonna

 never produeea offaeta. A comparison of the aupplemmtary 

 illuitration, which wae drawn by Mr. Worthington (Smith from 

 the indoreaeeaaee tent from my garden, with the engraving in 

 the Garden above cited, lead* to the conclusion that the Kew 

 plant can no longer be regarded aa a hybrid Mweea theae i

 Ammrylii* oe/texfoM aa the female plant. In that case the
